“ NATURE” says

“The new illustrated catalogue of physical apparatus just issued by Messrs. F. E. Becker and Co. (Messrs. W. and J. George, Ltd.) is likely to prove indispensable in the physical laboratories of all our schools and colleges. It runs to 628 large pages, and is strongly bound in cloth. Full particulars are provided, not only respecting the apparatus required in elementary and advanced physical teaching, but also concerning that necessary to the physicist in his research work. All branches of physics are included, and the instruments throughout are explained by excellent illustrations and concise descriptions, and, what is of prime importance, the figure and its appropriate text are close together.”

“Messrs. F. E. Becker and Co. (W. and J. George, Ltd., Successors) have sent us a copy of their new list of apparatus in the various departments of Physics, including Sound, Light, Heat, Magnetism, Electricity, Mechanics, &c. This exhaustive catalogue consists of over 600 pages and some 4000 Illustrations. One of its noteworthy features is that the requirements of science teaching in this country and its colonies are always kept in view, and the articles listed cover the latest developments in their subjects. The method adopted in the list itself, together with the completeness of the index, is such as to make reference to it

AN INQUIRY INTO THE PSYCHIC POWERS

OF THESE ANIMALS.
With an Appendix on the Peculiarities of their Olfactory Sense.
Translated from the German by Professor W. M. WHEELER.

PAPER, 2/6.
LORD Avebury says, in the Daily Chronicle of September 26 :-

"From his life-long and conscientious study of Ants Dr. Forel is peculiarly qualified to write on such a subject ; while from his position at the head of a great lunatic asylum he bas bad exceptional opportunities, of which he has ably availed himself, for the study of mind in various phases. . . When we see an ant-hill, tenanted by thousands of industrious inhabitants, excavating chambers, forming tunnels, making roads, guarding their home, gathering food, feeding the young, tending their domestic animals-each one fulfilling its duties industriously and without confusir nit is difficult altogether to deny to them the gift of reason; and the preceding observations tend to confirm the opinion that their mental powers differ from those of men not so much in kind as in degree."

The Glasgow Herald says :-"Here at least one has a writer whose successful elimination of the personal element (in psychology more than all such an insidious enemy) must inevitably commend him to the genuine thinker." KEGAN PAUL, TRENCH, TRÜBNER & CO., Ltd.,
