Rh some sense to carry on the work of the great Belgian alienist. In the first part he describes the etiology, symptomatology, evolution and diagnostics of excitation. The second part deals with pathogeny and the cyclothymic traits in various mental states and in somatic diseases, especially its relations to gout and diabetes. The subsequent chapters deal with the treatment and with medico-legal considerations and provisions.

The first part deals with the great philosophers before Kant; the second with those since Kant ending with Compte, Mill and Spencer. It is a good little repetitorium for the history of philosophy.

This is the second edition of what appears to have been a successful compend dealing with the nature and definition of insanity, classification, cause, treatment, symptoms, examination, paranoia, manic-depressive psychoses, paresis, dementia prsecox, involution, melancholia, senile psychoses, infection, exhaustion and toxic psychoses, the psychoses associated with other diseases, borderland and episodic states, with an essay on imbecility.

This volume compares well with the author's important volume, "Pain, Pleasure and JEjsthetics." It is wrought out with great care. The first book deals with consciousness in general first, that of man; second, that of other than human forms. Book Second is on the general nature of human presentations, with first the general qualities of relation aroused in connection with all presentations; then the general qualities determined by complexity of presentations. Part II is on qualities of relation determined by the correlation of the general qualities studied in Part I. The third book is on the Self.

The author first experimented with college students and also trained psychologists and then upon spontaneous imagery of various kinds. He has clearly made an important contribution to this now very interesting subject.

Popular thought regards imitation as the chief function of monkey life; so that the author's experiments are so important and interesting as to give us much more respect than we had before for the intelligence of monkeys. Those who remember the newspaper notoriety these tests had in New York, where they were made, will be agreeably disappointed to find that they are really scientific.
