the zoospore-formation in Microthauuiion is most like that of 

 Myxonciiia {Stigcocloiiiuui), and Goiigrosira and Leptosira may 

 well be placed (as by Blackman and Tansley) in the Trente- 

 pohliaceae. 



In the matter of nomenclature, the author has shown an open- 

 minded regard for priority, though one may wonder why, while 

 taking up Choaspis S. F. Gray for Sirogonutm Kiitz., he does 

 not also revive AgardJiia of the same work in place of Mongcotia. 

 An unusual degree of familiarity with recent American work is 

 evident, and the numerous references to such literature are 

 among many good features which will commend this book to 

 American students and teachers. Tracy E. Hazen. 



The Teaching of Biology in the Secondary School* 



The volume recently issued under the above title is one of the 

 American Teachers Series, edited by Professor James E. Russell, 

 Dean of the Teachers College, Columbia University The two 

 authors have charge, respectively, of the botanical and zoological 

 work in the Teachers College and the present volume consists of 

 two parts, the first on " The Teaching of Botany and of Nature 

 Study," written by Professor Lloyd, and the second on "The 

 Teaching of Zoology, including Human Physiology, in the Sec- 

 ondary School," written by Professor Bigelow. As is sufficiently 

 indicated in the titles, the work is not a laboratory manual for 

 the student, but aims to cover the much less occupied field of a 

 manual for teachers. In fact, on the botanical side, " The Teach- 

 ing Botanist," of Professor Ganong, is the only book known to 

 the reviewer which may fairly be compared with it, a comparison 

 which is invited, not only by the general similarity in the scope 

 of the two works, but also by Professor Lloyd's frequent citation 

 of " The Teaching Botanist " and by the association of Professors 

 Ganong and Lloyd on the committee appointed by the Society 

 for Plant Morphology and Physiology to consider the formula- 

 tion of a standard college entrance option in botany. Whatever
