Foods. 
By Dr. EDWARD SMITH. 
Ivol.,12mo. Cloth. Illustrated. . . . . . . . Price, $1.75. 
In making up THE INTERNATIONAL SCIENTIFIC SERIES, Dr. Edward Smith was se- 
lected as the ablest man in England to treat the important subject of Foods.” His services 
were secured for the undertaking, and the little treatise he has produced shows that the 
choice of a writer on this subject was most fortunate, as the book is unquestionably the 
clearest and best-digested compend of the Science of Foods that has appeared in our 
language. J 
‘‘The book contains a series of diagrams, displaying the effects of sleep and meals 
on pulsation and respiration, and of various kinds of food on respiration, which, as the 
results of Dr. Smith’s own experiments, possess a very high value. We have not far 
to go in this work for occasions of favorable criticism; they occur throughout, but are 
perhaps most apparent in those parts of the subject with which Dr. Smith’s name is es- 
pecially linked.” —London Examiner. 
‘* The union of scientific and popular treatment in the composition of this work will 
afford an attraction to many readers who would have been indifferent to purely theoreti- 
cal details. . . . Still his work abounds in information, much of which is of great value, 
and a part of which could not easily be obtained from other sources. Its interest is de- 
cidedly enhanced for students who demand both clearness and exactness of statement, 
by the profusion of well-executed woodcuts, diagrams, and tables, which accompany the 
volume... . The suggestions of the author on the use of tea and coffee, and of the va- 
rious forms of alcohol, although perhaps not strictly of a novel character, are highly in- 
structive, and form an interesting portion of the volume.”—WV. VY. Tribune.

Body and Mind. 
THE THEORIES OF THEIR RELATION. 
By ALEXANDER BAIN, LL. D. 
Tey olen omoe eCloth- ya cium. Soc os Ua ay ve cea wn mICe, mais Os 
ProFeEssor BAIn is the author of two well-known standard works upon the Science 
of Mind—‘‘ The Senses and the Intellect,” and ‘‘ The Emotions and the Will.” He is 
one of the highest living authorities in the school which holds that there can be no sound 
or valid psychology unless the mind and the body are studied, as they exist, together. 
““Tt contains a forcible statement of the connection between mind and body, study- 
ing their subtile interworkings by the light of the most recent physiological investiga- 
tions. The summary in Chapter V., of the investigations of Dr. Lionel Beale of the 
embodiment of the intellectual functions in the cerebral system, will be found the 
freshest and most interesting part of his book. Prof. Bain’s own theory of the ccnnec- 
tion between the mental and the bodily part in manis stated by himself to be as follows: 
There is ‘one substance, with two sets of properties, two sides, the physical and the 
mental—a double-faced unity.’ While, in the strongest manner, asserting the union 
of mind with brain, he yet denies ‘the association of union zz dace,’ but asserts the 
union of close succession in time,’ holding that ‘the same being is, by alternate fits, un- 
der extended and under unextended consciousness.” ’—Christian Register.
