Chapter 16

It is a sure sign of a clear, sound understanding and a good temperament when the profile of the forehead has two proportionate arches, the lower of which projects.

Eyebones with well-marked, firm arches I never saw but in noble and great men.

Square foreheads with extensive temples and firm eyebones show circumspection and steadiness of character.

Perpendicular wrinkles, if natural, denote application and power. Horizontal wrinkles and those broken in the middle or at the extremities generally denote negligence or want of power.

Perpendicular, deep indentings in the forehead between the eyebrows, I never met save in men of sound understanding and free and noble minds, unless there were some positively contradictory feature.

A blue frontal vein, in the form of a Y, when in an open, smooth, well-arched forehead, I have only found in men of extraordinary talents and of ardent and generous character.

The following are the traits of a perfectly beautiful, intelligent, and noble forehead.

In length it must equal the nose, or the under part of the face. In breadth it must be either oval at the top-like the foreheads of most of the great men of England--or nearly square. It must be free from unevenness and wrinkles, yet be able to wrinkle when deep in thought, afflicted by pain, or moved by indignation. It must retreat above and project beneath. The eyebones must be simple, horizontal, and, if seen from above, must present a simple curve. There should be a small cavity in the centre, from above to below, and traversing the forehead so as to separate it into four divisions perceptible in a clear descending light. The skin must be more clear on the forehead than in other parts of the countenance.

Foreheads short, wrinkled, and knotty, are incapable of durable friendship.

Be not discouraged though a friend, an enemy, a child, or a brother transgress, for so long as he have a good, well-proportioned, open forehead there is still hope of improvement.

THE EYES AND EYEBROWS. Blue eyes are generally more indicative of weakness and effeminacy than brown or black. Certainly there are many powerful men with blue eyes, but I find more strength, manhood, thought with brown.

Choleric men have eyes of every colour, but rather brown or greenish than blue. A propensity to green is an almost decisive token of ardour, fire, and courage.

Wide open eyes, with the white visible, I have often observed both in the timid and phlegmatic, and in the courageous and rash.

Meeting eyebrows were supposed to be the mark of craft, but I do not believe them to have this significance. Angular, strong, interrupted eyebrows denote fire and productive activity. The nearer the eyebrows to the eyes, the more earnest, deep, and firm the character. Eyebrows remote from each other denote warm, open, quick sensations. White eyebrows signify weakness; and dark brown, firmness. The motion of the eyebrows contains numerous expressions, especially of ignoble passions.

THE NOSE. I have generally considered the nose the foundation or abutment of the brain, for upon this the whole power of the arch of the forehead rests. A beautiful nose will never be found accompanying an ugly countenance. An ugly person may have fine eyes, but not a handsome nose.

I have never seen a nose with a broad back, whether arched or rectilinear, that did not belong to an extraordinary man. Such a nose was possessed by Swift, Cæsar Borgia, Titian, etc. Small nostrils are usually an indubitable sign of unenterprising timidity. The open, breathing nostril is as certain a token of sensibility.

THE MOUTH AND LIPS. The contents of the mind are communicated to the mouth. How full of character is the mouth! As are the lips, so is the character. Firm lips, firm character; weak lips, weak character. Well-defined, large, and proportionate lips, the middle line of which is equally serpentine on both sides, and easy to be drawn, are never seen in a bad, mean, common, false, vicious countenance. A lipless mouth, resembling a single line, denotes coldness, industry, a love of order, precision, house-wifery, and, if it be drawn upwards at the two ends, affectation, pretension, vanity, malice. Very fleshy lips have always to contend with sensuality and indolence. Calm lips, well closed, without constraint, and well delineated, certainly betoken consideration, discretion, and firmness. Openness of mouth speaks complaint, and closeness, endurance.

THE CHIN. From numerous experiments, I am convinced that the projecting chin ever denotes something positive, and the retreating something negative. The presence or absence of strength in man is often signified by the chin.

I have never seen sharp indentings in the middle of the chin save in men of cool understanding, unless when something evidently contradictory appeared in the countenance. The soft, fat, double chin generally points out the epicure; and the angular chin is seldom found save in discreet, well-disposed, firm men. Flatness of chin speaks the cold and dry; smallness, fear; and roundness, with a dimple, benevolence.

SKULLS. HOW much may the anatomist see in the mere skull of man! How much more the physiognomist! And how much more still the anatomist who is a physiognomist! If shown the bald head of Cæsar, as painted by Rubens or Titian or Michael Angelo, what man would fail to notice the rocky capacity which characterises it, and to realise that more ardour and energy must be expected than from a smooth, round, flat head? How characteristic is the skull of Charles XII.! How different from the skull of his biographer Voltaire! Compare the skull of Judas with the skull of Christ, after Holbein, and I doubt whether anyone would fail to guess which is the skull of the wicked betrayer and which the skull of the innocent betrayed. And who is unacquainted with the statement in Herodotus that it was possible on the field of battle to distinguish the skulls of the effeminate Medes from the skulls of the manly Persians? Each nation, indeed, has its own characteristic skull.

_III.--Nation, Sex, and Family_

NATIONAL PHYSIOGNOMY. It is undeniable that there is a national physiognomy as well as national character. Compare a negro and an Englishman, a native of Lapland and an Italian, a Frenchman and an inhabitant of Tierra del Fuego. Examine their forms, countenances, characters, and minds. This difference will be easily seen, though it will sometimes be very difficult to describe it scientifically.

The following infinitely little is what I have hitherto observed in the foreigners with whom I have conversed.

I am least able to characterise the French, They have no traits so bold as the English, nor so minute as the Germans. I know them chiefly by their teeth and their laugh. The Italians I discover by the nose, small eyes, and projecting chin. The English by their foreheads and eyebrows. The Dutch by the rotundity of their heads and the weakness of the hair. The Germans by the angles and wrinkles round the eyes and in the cheeks. The Russians by the snub nose and their light-coloured or black hair.

I shall now say a word concerning Englishmen in particular. Englishmen have the shortest and best-arched foreheads--that is to say, they are arched only upwards, and, towards the eyebrows, either gently recline or are rectilinear. They seldom have pointed, usually round, full noses. Their lips are usually large, well defined, beautifully curved. Their chins are round and full. The outline of their faces is in general large, and they never have those numerous angles and wrinkles by which the Germans are so especially distinguished. Their complexion is fairer than that of the Germans.

All Englishwomen whom I have known personally, or by portrait, appear to be composed of marrow and nerve. They are inclined to be tall, slender, soft, and as distant from all that is harsh, rigorous, or stubborn as heaven is from earth.

The Swiss have generally no common physiognomy or national character, the aspect of fidelity excepted. They are as different from each other as nations the most remote.

THE PHYSIOGNOMICAL RELATION OF THE SEXES. Generally speaking, how much more pure, tender, delicate, irritable, affectionate, flexible, and patient is woman than man. The primary matter of which woman is constituted appears to account for this difference. All her organs are tender, yielding, easily wounded, sensible, and receptive; they are made for maternity and affection. Among a thousand women, there is hardly one without these feminine characteristics.

This tenderness and sensibility, the light texture of their fibres and organs, render them easy to tempt and to subdue, and yet their charms are more potent than the strength of man. Truly sensible of purity, beauty and symmetry, woman does not always take time to reflect on spiritual life, spiritual death, spiritual corruption.

The woman does not think profoundly; profound thought is the prerogative of the man; but women feel more. They rule with tender looks, tears, and sighs, but not with passion and threats, unless they are monstrosities. They are capable of the sweetest sensibility, the deepest emotion, the utmost humility, and ardent enthusiasm. In their faces are signs of sanctity which every man honours.

Owing to their extreme sensibility and their incapacity for accurate inquiry and firm decision, they may easily become fanatics.

The love of women, strong as it is, is very changeable; but their hatred is almost incurable, and is only to be overcome by persistent and artful flattery. Men usually see things as a whole, whereas women take more interest in details.

Women have less physical courage than men. Man hears the bursting thunders, views the destructive bolt with serene aspect, and stands erect amid the fearful majesty of the torrent. But woman trembles at the lightning and thunder, and seeks refuge in the arms of man.

Woman is formed for pity and religion; and a woman without religion is monstrous; and a woman who is a freethinker is more disgusting than a woman with a beard.

Woman is not a foundation on which to build. She is the gold, silver, precious stones, wood, hay, stubble--the materials for building on the male foundation. She is the leaven, or, more expressly, she is oil to the vinegar of man. Man singly is but half a man, only half human--a king without a kingdom. Woman must rest upon the man, and man can be what he ought to be only in conjunction with the woman.

Some of the principal physiognomical contrasts may be summarised here.

Man is the most firm; woman the most flexible.

Man is the straightest; woman the most bending.

Man stands steadfast; woman gently retreats.

Man surveys and observes; woman glances and feels.

Man is serious; woman is gay.

Man is the tallest and broadest; woman the smallest and weakest.

Man is rough and hard; woman is smooth and soft.

Man is brown; woman is fair.

The hair of the man is strong and short; the hair of woman is pliant and long.

Man has most straight lines; woman most curved.

The countenance of man, taken in profile, is not so often perpendicular as that of woman.

FAMILY PHYSIOGNOMY. The resemblance between parents and children is very commonly remarkable. Family physiognomical resemblance is as undeniable as national physiognomical resemblance. To doubt this is to doubt what is self-evident.

When children, as they increase in years, visibly increase in their physical resemblance to their parents, we cannot doubt that resemblance in character also increases. Howsoever much the character of children may seem to differ from that of their parents, yet this difference will be found to be due to great difference in external circumstances.

JUSTUS VON LIEBIG

Animal Chemistry

Baron Freiherr Justus von Liebig, one of the most illustrious chemists of his age, was born on May 12, 1803, at Darmstadt, Germany, the son of a drysalter. It was in his father's business that his interest in chemistry first awoke, and at fifteen he became an apothecary's assistant. Subsequently, he went to Erlangen, where he took his doctorate in 1822; and afterwards, in Paris, was admitted to the laboratory of Gay-Lussac as a private pupil. In 1824 he was appointed a teacher of chemistry in the University of Giessen in his native state. Here he lived for twenty-eight years a quiet life of incessant industry, while his fame spread throughout Europe. In 1845 he was raised to the hereditary rank of baron, and seven years later was appointed by the Bavarian government to the professorship of chemistry in the University of Munich. Here he died on April 18, 1873. The treatise on "Animal Chemistry, or Organic Chemistry in its Relations to Physiology and Pathology," published in 1842, sums up the results of Liebig's investigations into the immediate products of animal life. He was the first to demonstrate that the only source of animal heat is that produced by the oxidation of the tissues.

_I.--Chemical Needs of Life_

Animals, unlike plants, require highly organised atoms for nutriment; they can subsist only upon parts of an organism. All parts of the animal body are produced from the fluid circulating within its organism. A destruction of the animal body is constantly proceeding, every motion is the result of a transformation of its structure; every thought, every sensation is accompanied by a change in the composition of the substance of the brain. Food is applied either in the increase of the mass of a structure (nutrition) or in the replacement of a structure wasted (reproduction).

Equally important is the continual absorption of oxygen from the atmosphere. All vital activity results from the mutual action of the oxygen of the atmosphere and the elements of food. According to Lavoisier, an adult man takes into his system every year 827 lb. of oxygen, and yet he does not increase in weight. What, then, becomes of this oxygen?--for no part of it is again expired as oxygen. The carbon and hydrogen of certain parts of the body have entered into combination with the oxygen introduced through the lungs and through the skin, and have been given out in the form of carbonic acid and the vapour of water.

Now, an adult inspires 32-1/2 oz. of oxygen daily; this will convert the carbon of 24 lb. of blood (80 per cent. water) into carbonic acid. He must, therefore, take as much nutriment as will supply the daily loss. And, in fact, it is found that he does so; for the average amount of carbon in the daily food of an adult man is 14 oz., which requires 37 oz. of oxygen for its conversion into carbonic acid. The amount of food necessary for the support of the animal body must be in direct ratio to the quantity of oxygen taken into the system. A bird deprived of food dies on the third day; while a serpent, which inspires a mere trace of oxygen, can live without food for three months. The number of respirations is less in a state of rest than in exercise, and the amount of food necessary in both conditions must vary also.

The capacity of the chest being a constant quantity, we inspire the same volume of air whether at the pole or at the equator; but the weight of air, and consequently of oxygen, varies with the temperature. Thus, an adult man takes into the system daily 46,000 cubic inches of oxygen, which, if the temperature be 77° F., weighs 32-1/2 oz., but when the temperature sinks to freezing-point will weigh 35 oz. It is obvious, also, that in an equal number of respirations we consume more oxygen at the level of the sea than on a mountain. The quantity of oxygen inspired and carbonic acid expired must, therefore, vary with the height of the barometer. In our climate the difference between summer and winter in the carbon expired, and therefore necessary for food, is as much as one-eighth.

_II.--The Cause of Animal Heat_

Now, the mutual action between the elements of food and the oxygen of the air is the source of animal heat.

This heat is wholly due to the combustion of the carbon and hydrogen in the food consumed. Animal heat exists only in those parts of the body through which arterial blood (and with it oxygen in solution) circulates; hair, wool, or feathers, do not possess an elevated temperature.

As animal heat depends upon respired oxygen, it will vary according to the respiratory apparatus of the animal. Thus the temperature of a child is 102° F., while that of an adult is 99-1/2° F. That of birds is higher than that of quadrupeds or that of fishes or amphibia, whose proper temperature is 3° F higher than the medium in which they live. All animals, strictly speaking, are warm-blooded; but in those only which possess lungs is their temperature quite independent of the surrounding medium. The temperature of the human body is the same in the torrid as in the frigid zone; but the colder the surrounding medium the greater the quantity of fuel necessary to maintain its heat.

The human body may be aptly compared to the furnace of a laboratory destined to effect certain operations. It signifies nothing what intermediate forms the food, or fuel, of the furnace may assume; it is finally converted into carbonic acid and water. But in order to sustain a fixed temperature in the furnace we must vary the quantity of fuel according to the external temperature.

In the animal body the food is the fuel; with a proper supply of oxygen we obtain the heat given out during its oxidation or combustion. In winter, when we take exercise in a cold atmosphere, and when consequently the amount of inspired oxygen increases, the necessity for food containing carbon and hydrogen increases in the same ratio; and by gratifying the appetite thus excited, we obtain the most efficient protection against the most piercing cold. A starving man is soon frozen to death; and everyone knows that the animals of prey in the Arctic regions far exceed in voracity those in the torrid zone. In cold and temperate climates, the air, which incessantly strives to consume the body, urges man to laborious efforts in order to furnish the means of resistance to its action, while in hot climates the necessity of labour to provide food is far less urgent.

Our clothing is merely the equivalent for a certain amount of food.

The more warmly we are clothed the less food we require. If in hunting or fishing we were exposed to the same degree of cold as the Samoyedes we could with ease consume ten pounds of flesh, and perhaps half a dozen tallow candles into the bargain. The macaroni of the Italian, and the train oil of the Greenlander and the Russian, are fitted to administer to their comfort in the climate in which they have been born.

The whole process of respiration appears most clearly developed in the case of a man exposed to starvation. Currie mentions the case of an individual who was unable to swallow, and whose body lost 100 lb. in one month. The more fat an animal contains the longer will it be able to exist without food, for the fat will be consumed before the oxygen of the air acts upon the other parts of the body.

There are various causes by which force or motion may be produced. But in the animal body we recognise as the ultimate cause of all force only one cause, the chemical action which the elements of the food and the oxygen of the air mutually exercise on each other. The only known ultimate cause of vital force, either in animals or in plants, is a chemical process. If this be prevented, the phenomena of life do not manifest themselves, or they cease to be recognisable by our senses. If the chemical action be impeded, the vital phenomena must take new forms.

The heat evolved by the combustion of carbon in the body is sufficient to account for all the phenomena of animal heat. The 14 oz. of carbon which in an adult are daily converted into carbonic acid disengage a quantity of heat which would convert 24 lb. of water, at the temperature of the body, into vapour. And if we assume that the quantity of water vaporised through the skin and lungs amounts to 3 lb., then we have still a large quantity of heat to sustain the temperature of the body.

_III.--The Chemistry of Blood-Making_

Physiologists conceive that the various organs in the body have originally been formed from blood. If this be admitted, it is obvious that those substances alone can be considered nutritious that are capable of being transformed into blood.

When blood is allowed to stand, it coagulates and separates into a watery fluid called serum, and into the clot, which consists principally of fibrine. These two bodies contain, in all, seven elements, among which sulphur, phosphorus, and nitrogen are found; they contain also the earth of bones. The serum holds in solution common salt and other salts of potash and soda, of which the acids are carbonic, phosphoric, and sulphuric acids. Serum, when heated, coagulates into a white mass called albumen. This substance, along with the fibrine and a red colouring matter in which iron is a constituent, constitute the globules of blood.

Analysis has shown that fibrine and albumen are perfectly identical in chemical composition. They may be mutually converted into each other. In the process of nutrition both may be converted into muscular fibre, and muscular fibre is capable of being reconverted into blood.

All parts of the animal body which form parts of organs contain nitrogen. The principal ingredients of blood contain 17 per cent. of nitrogen, and there is no part of an active organ that contains less than 17 per cent. of this element.

The nutritive process is simplest in the case of the carnivora, for their nutriment is chemically identical in composition with their own tissues. The digestive apparatus of graminivorous animals is less simple, and their food contains very little nitrogen. From what constituents of vegetables is their blood produced?

Chemical researches have shown that all such parts of vegetables as can afford nutriment to animals contain certain constituents which are rich in nitrogen; and experience proves that animals require for their nutrition less of these parts of plants in proportion as they abound in the nitrogenised constituents. These important products are specially abundant in the seeds of the different kinds of grain, and of peas, beans, and lentils. They exist, however, in all plants, without exception, and in every part of plants in larger or smaller quantity. The nitrogenised compounds of vegetables are called vegetable fibrine, vegetable albumen, and vegetable casein. All other nitrogenised compounds occurring in plants are either rejected by animals or else they occur in the food in such very small proportion that they cannot possibly contribute to the increase of mass in the animal body.

The chemical analysis of these three substances has led to the interesting result that they contain the same organic elements, united in the same proportion by weight; and--which is more remarkable--that they are identical in composition with the chief constituents of blood--animal fibrine and animal albumen. By identity, be it remarked, is not here meant merely similarity, but that even in regard to the presence and relative amounts of sulphur, phosphorus, and phosphate of lime no difference can be observed.
