It is a pathetic coincidence that the words 

 which Dr. Dall applied in this journal to 

 the late Professor Beecher should so soon 

 find an exact application to Beecher 's 

 former colleague in the Yale Museum : ' The 

 ranks of those capable of bringing to the 

 study of fossils keen insight and a philo- 

 sophical spirit of inquiry, g-uided by prin- 

 ciples whose value can hardly be exagger- 

 ated, are diminished by one whom science 

 could ill afford to lose, and to whom, hu- 

 manly speaking, there should have re- 

 mained many yeai'S of 'industry and fruit- 

 ful research.' W. B. Scott.

SCIENTIFIC BOOKS. 

 Adolescence; Us Psychology and its Relations 



to Physiology, Anthropology, Sociology, 



Bex, Crime, Religion and Education. By 



G. Stanley Hall. ISTew York, D. Appleton 



and Company. 1904. 



The range of President Hall's two volumes 

 is even wider than the title announces. Be- 

 sides the topics there indicated, the book con- 

 tains an ontline of the author's general psy- 

 chological system, a philosophical credo, and 

 multitudinous comments on the psychology of 

 early childhood and adult life. The thirteen 

 hundred and more pages are somewhat evenly 

 divided among physical, psychological, social 

 and miscellaneous phenomena. The author's 

 division is as follows : 



Volume I. — Growth in height and weight, 

 50 pages; growth of parts and organs during 

 adolescence, 78 pages ; growth of motor power 

 and function, 108 pages; diseases of body and 

 mind, 88 pages; juvenile faults, immoralities 

 and crimes, 86 pages ; sexual development : its 

 dangers and hygiene in boys, 61 pages ; 

 periodicity, 41 pages ; adolescence in literature, 

 biography and history, 77 pages. 



Volume II. — Changes in the senses and the 

 voice, 39 pages; evolution of the feelings and 

 instincts characteristic of normal adolescence, 

 65 pages; adolescent love, 49 pages; adolescent 



feelings toward nature and a new education 

 in science, 88 pages; savage pubic initiations, 

 classical ideals and customs and church con- 

 firmation, 49 pages; the adolescent psychology 

 of conversion, 82 pages; social instincts and 

 institutions, 86 pages; intellectual develop- 

 ment and education, 112 pages; adolescent 

 girls and their education, 87 pages; ethnic 

 psychology and pedagogy, or adolescent races 

 and their treatment, 101 pages. 



The stiident will naturally divide the book 

 as a whole into : (1) An array of facts bearing 

 upon its topics, (2) an attempt to establish a 

 parallelism between the mental development 

 of human individuals and that of the whole 

 phylum at one extreme of which they stand 

 and (3) the author's educational recommenda- 

 tions. The reviewer will follow this division. 



The array of facts presented implies an 

 astonishing labor in reading, selecting and 

 condensing. Over two thousand writers are 

 quoted or referred to. -Whoever has made 

 any pretense of saying- a scientific word about 

 the rich life of concrete human nature, we 

 may expect to find summarized. Be it the 

 love of children for cats or growth of thoracic 

 capacity or the lives of the saints. President 

 Hall is equally ready with varied comment 

 and plenteous references. No one person 

 could estimate the completeness, accuracy and 

 relevancy of this body of information as a 

 whole. If the citations and summaries under 

 each topic do represent adequately the views 

 of the experts, President Hall's tremendous 

 zeal will result in a corresponding saving of 

 time and gain in insight for future students. 

 If they do not, very many will be misled. In 

 any case the array of information will, in 

 these volumes as in the author's teaching, 

 stimulate and suggest. In those fields where 

 the reviewer could presume to judge, there ap- 

 pears an unhappy tendency toward the selec- 

 tion of authors and extracts which fit Presi- 

 dent Hall's own prepossessions. And this 

 suspicion is too frequently confirmed in cases 

 where expertness is not requisite. We tend 

 to lose confidence in no matter how eminent 

 a scholar, when, in a description of ' Adoles- 

 cence in Literature and Biography,' he gives 

 a thousand words to a summary of Mary lie-
