Animal Intelligence.

"My object in the work as a whole is twofold: First, I have thought it desirable that there should be something resembling a text-book of the facts of Comparative Psychology, to which men of science, and also metaphysicians, may turn whenever they have occasion to acquaint themselves with the particular level of intelligence to which this or that species of animal attains. My second and much more important object is that of considering the facts of animal intelligence in their relation to the theory of descent."—From the Preface.

"Unless we are greatly mistaken, Mr. Romanes's work will take its place as one of the most attractive volumes of the International Scientific Series. Some persons may, indeed, be disposed to say that it is too attractive, that it feeds the popular taste for the curious and marvelous without supplying any commensurate discipline in exact scientific reflection; but the author has, we think, fully justified himself in his modest preface. The result is the appearance of a collection of facts which will be a real boon to the student of Comparative Psychology, for this is the first attempt to present systematically well-assured observations on the mental life of animals."—Saturday Review.

"The author believes himself, not without ample cause, to have completely bridged the supposed gap between instinct and reason by the authentic proofs here marshaled of remarkable intelligence in some of the higher animals. It is the seemingly conclusive evidence of reasoning powers furnished by the adaptation of means to ends in cases which can not be explained on the theory of inherited aptitude or habit."—New York Sun.

"The high standing of the author as an original investigator is a sufficient guarantee that his task has been conscientiously carried out. His subject is one of absorbing interest. He has collected and classified an enormous amount of information concerning the mental attributes of the animal world. The result is astonishing. We find marvelous intelligence exhibited not only by animals which are known to be clever, but by others seemingly without a glimmer of light, like the snail, for instance. Some animals display imagination, others affection, and so on. The psychological portion of the discussion is deeply interesting."—New York Herald.

"The chapter on monkeys closes this excellent work, and perhaps the most instructive portion of it is that devoted to the life-history of a monkey."—New York Times.

"Mr. Romanes brings to his work a wide information and the best of scientific methods. He has carefully culled and selected an immense mass of data, choosing with admirable skill those facts which are really significant, and rejecting those which lacked sustaining evidence or relevancy. The contents of the volume are arranged with reference to the principles which they seem to him to establish. The volume is rich and suggestive, and a model in its way."—Boston Courier.

"It presents the facts of animal intelligence in relation to the theory of descent, supplementing Darwin and Spencer in tracing the principles which are concerned in the genesis of mind."—Boston Commonwealth.

"One of the most interesting volumes of the series."—New York Christian at Work.

"Few subjects have a greater fascination for the general reader than that with which this book is occupied."—Good Literature, New York.

Ants, Bees, and Wasps.

A Record of Observations on the Habits of the Social Hymenoptera.
By Sir JOHN LUBBOCK, Bart., M. P., F. R. S., etc.,
Author of "Origin of Civilization, and the Primitive Condition of Man," etc., etc.
—————————
With Colored Plates. 12mo. Cloth, $2.00.—————————

"This volume contains the record of various experiments made with ants, bees, and wasps during the last ten years, with a view to test their mental condition and powers of sense. The principal point in which Sir John's mode of experiment differs from those of Huber, Forel, McCook, and others, is that he has carefully watched and marked particular insects, and has had their nests under observation for long periods—one of his ants' nests having been under constant inspection ever since 1874. His observations are made principally upon ants because they show more power and flexibility of mind; and the value of his studies is that they belong to the department of original research."

"We have no hesitation in saying that the author has presented us with the most valuable series of observations on a special subject that has ever been produced, charmingly written, full of logical deductions, and, when we consider his multitudinous engagements, a remarkable illustration of economy of time. As a contribution to insect psychology, it will be long before this book finds a parallel."—London Athenæum.

"These studies, when handled by such a master as Sir John Lubbock, rise far above the ordinary dry treatment of such topics. The work is an effort made to discover what are the general, not the special, laws which govern communities of insects composed of inhabitants as numerous as the human beings living in London and Peking, and who labor together in the utmost harmony for the common good. That there are remarkable analogies between societies of ants and human beings no one can doubt. If, according to Mr. Grote, 'positive morality under some form or other has existed in every society of which the world has ever had experience,' the present volume is an effort to show whether this passage be correct or not."—New York Times.

"In this work the reader will find the record of a series of experiments and observations more thorough and ingenious than those instituted by any of the accomplished author's predecessors. . . . . Sir John has been a close observer of the habits of ants for many years, generally having from thirty to forty communities under his notice, and not only watching each of these in its carefully isolated glass house, but, by the use of paint-marks, following the fortunes of individuals. . . . . One notable result of this system has been the correcting of previous theories as to the age to which ants attain: instead of living merely a year, as the popular belief has been, some of Sir John's queens and workers are thriving after being under observation since 1874 and 1875."—New York World.

"Sir John Lubbock's book on 'Ants, Bees, and Wasps' is mainly devoted to the crawlers, and not the fliers, though he has some observations upon honey-bees and more interesting ones upon the unpopular wasp, which he fondly deems to be capable of gratitude. Darwin made a strong case for the monkeys, but Lubbock may yet make us out to be, as Irishmen say, 'The sons of our ants.' For he begins his entertaining book thus: 'The anthropoid apes no doubt approach nearer to man in bodily structure than do any other animals, but, when we consider the habits of ants, their large communities and elaborate habitations, their roadways, their possession of domestic animals, and, even in some cases, of slaves, it must be admitted that they have a fair claim to rank next to man in the scale of intelligence.'"—Springfield Republican.
