Animal Intelligence The International Scientific Series, Vol. XLIV.

I HAVE recently learnt from the publishers of the 'International Scientific Series' that they have made arrangements with Sir John Lubbock to bring out in the same series a work...

BEFORE we begin to consider the phenomena of mind throughout the animal kingdom it is desirable that we should understand, as far as possible, what it is that we exactly mean by...

NO one can have watched the movements of certain Infusoria without feeling it difficult to believe that these little animals are not actuated by some amount of intelligence. Eve...

I SHALL treat of the Mollusca before the Articulata, because as a group their intelligence is not so high. Indeed, it is not to be expected that the class of animals wherein the...

WITHIN the last ten or twelve years our information on the habits and intelligence of these insects has been so considerably extended, that in here rendering a condensed epitome...

Bees and wasps have much greater powers of sight than ants. They not only perceive objects at a greater distance, but are also able to distinguish their colours. This was proved...

THE habits of the Termites, or so-called White Ants, have not been so closely studied as they deserve. Our chief knowledge concerning them is derived from the observations of Jo...

THE emotional life of spiders, so far as we can observe it as expressed in their actions, seems to be divided between sexual passion (including maternal affection) and the stern...

THE Hymenoptera being so much the most intelligent order, not merely of insects, but of Invertebrata, and the Arachnida having been now considered, very little space need be occ...

ALTHOUGH we here pass into the sub-kingdom of animals the intelligence of which immeasurably surpasses that of the other sub-kingdoms, it is remarkable that these lowest represe...

ON the intelligence of frogs and toads very little has to be said. Frogs seem to have definite ideas of locality; for several of my correspondents inform me that they have known...

ADEQUATELY to treat of the intelligence of birds a separate volume would be required; here it must be enough to deal with this class as I shall afterwards deal with the Mammalia...

[145] _Curiosities_, &c., p. 126. Wilson also, in his _American Ornithology_, gives the following sufficiently credible account of the memory of a crow:--'A gentleman who reside...

I SHALL devote this chapter to the psychology of all the Mammalia which present any features of psychological interest, with the exception of the rodents, the elephant, the dog...

THE rodents, psychologically considered, are, of all orders in the animal kingdom, most remarkable for the differences presented by constituent species. For while the group cont...

THE intelligence of the elephant is no doubt considerable, although there is equally little doubt that it is generally exaggerated. Some of the most notorious instances of the d...

THE cat is unquestionably a highly intelligent animal, though when contrasted with its great domestic rival, the dog, its intelligence, from being cast in quite a different moul...

THE general psychology of these animals is, of course, very much the same as that of the dog; but, from never having been submitted to the influences of domestication, their men...

THE intelligence of the dog is of special, and indeed of unique interest from an evolutionary point of view, in that from time out of record this animal has been domesticated on...

WE now come to the last group of animals which we shall have occasion to consider, and these, from an evolutionary point of view, are the most interesting. Unfortunately, howeve...
