Its interest is decidedly 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 various forms of alcohol, although perhaps not
strictly of a novel character, are highly instructive, and form an
interesting portion of the volume."--_N. Y. Tribune._

Body and Mind.

THE THEORIES OF THEIR RELATION.

By ALEXANDER BAIN, LL.D.

1 vol., 12mo. Cloth Price, $1.50.

PROFESSOR 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.

"It contains a forcible statement of the connection between
mind and body, studying their subtile interworkings by the
light of the most recent physiological investigations. 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 connection between the
mental and the bodily part in man is 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 _in place_,'
but asserts the union of close succession in time,' holding that
'the same being is, by alternate fits, under extended and under
unextended consciousness.'"--_Christian Register._

The Study of Sociology.

By HERBERT SPENCER.

1 vol., 12mo. Cloth Price, $1.50.

"The philosopher whose distinguished name gives weight and
influence to this volume, has given in its pages some of the
finest specimens of reasoning in all its forms and departments.
There is a fascination in his array of facts, incidents, and
opinions, which draws on the reader to ascertain his conclusions.
The coolness and calmness of his treatment of acknowledged
difficulties and grave objec
