Part 206

_Obs._ The preceding formulæ are at present employed in the wholesale trade, by nearly all those houses that are most noted for the superior quality of their 'CONCENTRATED INFUSIONS,' The products of the whole are excellent. That from _c_ is very beautiful, and contains all the valuable active matter that it is possible to extract from the ingredients, under the circumstances. It also keeps well. The last one, like all preparations of senna made with hot water, is apt to drop a large deposit on standing, from which the last portion of the infusion is obtained with difficulty. They each furnish a liquid, of which 1 fl. dr. added to 7 fl. dr. of pure water forms 1 fl. oz. of a preparation precisely similar in medicinal qualities to the INFUSUM SENNÆ COMP.--Ph. L.

From the extreme bulkiness of senna, it has become a practice with certain unprincipled druggists to employ only 1/3 or 1/4 of the proper quantity of that drug, and to add burnt sugar or treacle to bring up the consistence and colour, and alkaline solution of gamboge to impart the necessary purgative quality. CONCENTRATED INFUSION OF SENNA, as generally met with, is nearly worthless. This arises from either the employment of inferior senna, or the destruction of its active principle, by the lengthened exposure to heat and atmospheric oxygen during its manufacture.

=INHALA'TION.= _Syn._ Inhalatio, L. In _medicine_, the drawing in or inspiring of vapour with the breath. Inhalations (INHALATIONES) are vapours or gases imbibed for the purpose of medicating the mucous membrane of the air-passages. The substances that are to furnish the vapours or fumes are put into a vessel called an 'inhaler' (see INHALER), which may be simply a small covered pot or mug of metal or glass, furnished with a short flexible tube, terminating in a small mouth-piece. In many cases even this simple apparatus may be dispensed with, and the fumes inhaled by holding the head over a vessel containing a little of the substance furnishing them; or, as with chloroform, a little may be dropped on a handkerchief or napkin, which is then held to the nose.

The following are the principal substances that are employed for inhalations at the present day:--

1. Carbonic acid gas and nitrous oxide; occasionally used in phthisis, by means of a bladder and mouth-piece.

2. Chlorine gas; exhibited by adding 5 or 6 drops of aqueous chlorine to the water (tepid) of the inhaler, which should be, in this case, of glass; employed in France for phthisis, but seldom used in England.

3. Chloroform; as an anæsthetic.

4. Vapour of iodine, administered in the same way as chlorine; occasionally used in phthisis.

5. Oxygen and hydrogen gases, either alone or diluted with air; employed in asthma and phthisis, by means of a bladder and mouth-piece.

6. Tar vapour, obtained by heating tar, mixed with a little carbonate of potash, over a spirit lamp, occasionally employed in bronchitis, and recommended by Sir A. Crighton in phthisis, but appears of little value in the latter.

7. Steam of hot water; in bronchitis, and to allay the cough in phthisis; small quantities of the seeds of henbane, opium, poppy-heads, &c., are frequently added to produce an anodyne effect. See CIGARS (in pharmacy), DISINFECTANTS, FUMIGATION, VAPOURS, &c.

=INJEC'TION.= _Syn._ INJECTIO, L. In _medicine_, any liquid medicine thrown into a cavity of the body by means of a syringe or an elastic bag.
