Medicine are scattered, abroad in various periodicals _ and trans- 
actions published in different languages and localities. The 
present issue is intended to render this excuse null and void for 
the future. The present volume consists of some twenty-three 
articles, most of them being full or summarised papers read by 
Dr. Thudichum before the Pathological Institute. One of the 
most interesting of these is the biography of the great German 
physicist, R. J. Mayer. No. XX. is also an interesting paper on 
the colouring-matters of bile, which appears to clear up satis- 
factorily much of the confusion that has hitherto reigned 
amongst these interesting bodies. There are two excellent 
name and subject indexes. 
We cannot agree, however, with Dr. Thudichum m advo- 
cating the introduction of such words as li to fell, i( hydrochlor, 
“ hydrothion,” and “ molecle,” for to precipitate, hydrochloric 
acid, hydrosulphuric acid, and molecule. 
Mind in the Lower Animals in Health and Disease. By W. 
Lauder Lindsay, M.D., F.R.S.E., F.L.S. London: C. 
Kegan Paul. 
We have here two goodly volumes on a subject which, though 
hitherto much negleaed, must be pronounced to be of the 
deepest interest. It will yet be seen that the attempt to consti- 
tute a science of mind from the exclusive study of the human 
species is no less a mistake than that of the old naturalists who 
began with a description of our bodily struaure, and then worked 
down to the lower organisms, thus going from the complex to 
the simple. . 
The author tells us that he has studied the subjea of mind in 
other animals, as compared with that of man, for a series of 
years, and that his point of view is that of a “ physician- 
naturalist.” His professional speciality being the treatment of 
mental alienation in man, he passed to the study of comparative 
pathology, the result of his inquiries being that the lower ani- 
mals are subjea to the same diseases as we are. Turning to 
psycho-pathology, he extended this conclusion to mental dis- 
orders, and was thus finally led to an “ investigation of the 
normal phenomena of mind throughout the animal kingdom.” 
Whether this way of entering upon the latter subjea is the 
happiest is perhaps open to doubt. He aims at indicating, first, 
the spirit and direaion in which such an inquiry ought to be 
prosecuted j secondly, its claims on our attention , thirdly, the 
desirability of exaaiy separating the known from the unknown ; 
fourthly, “ the new significance of certain faas as interpreted
