the predilections of the instructor and the 

 like. A rather careful reading of several sec- 

 tions reveals no serious faults, while typo- 

 graphical errors are few. We have not met 

 any directions for injection; although starch 

 mass is mentioned several times, no formulae 

 are given for its preparation. " Calkins " is 

 referred to several times, but the beginner can 

 hardly be expected to know of Calkins's work 

 on the Protozoa. Aside from this, references 

 to the literature are few. Lencosolenia occurs

Makers of Modern Medicine. By James J. 



Walsh. Pordham University Press. 1907. 



Dr. Walsh describes in this book the life 

 and works of several famous men who are in 

 a way the founders of modem medicine, but 

 the names are hardly those which one would 

 select as representing in a well-rounded way 

 the foundation of modern medicine as a whole, 

 since some of the very greatest are not men- 

 tioned. Vesalius, Harvey and Virchow would 

 certainly deserve places if there were any in- 

 tention of making such a complete list, but 

 in his preface Dr. Walsh explains that this is 

 a series of sketches which may be followed by 

 others. In these subsequent sketches we may 

 perhaps hope to find some mention of the 

 great surgeons who have done so much to help 

 in building the foundations. Morgagni, Auen- 

 brugger, Jenner, Galvani, Laennec, Graves, 

 Stokes and Corrigan, Miiller, Schwann, Ber- 

 nard, Pasteur and O'Dwyer form the subject 

 of the sketches, which are very uniform in 

 plan and general treatment. 



Perhaps the most striking thing in this uni- 

 formity is that every one of the men described 

 was of the Catholic faith and the essays in 

 each instance lead up to a discussion of their 

 devotion to the church, and to the dominant 

 idea that great scientific work is not incom- 

 patible with devout adherence to the tenets of 

 the Catholic religion. 



Dr. Walsh recognizes well the salient char- 

 acters of these men, the great teachers, the 

 great humanitarians, the toiling investiga- 

 tors and the brilliant geniuses who make one 

 step into the unknown, and makes clear too 



the interdependence of these qualities upon one 

 another in the truly great. Thus there seems 

 no doubt that in comparing Laennec with 

 Auenbrugger we must see that while their 

 most brilliant achievements were alike signal 

 advances in the art of physical diagnosis, 

 Laennec's power as a teacher, his discoveries 

 in the realm of pathological anatomy and his 

 deep human sympathies mark him out as a 

 man standing on a higher plane than that of 

 Auenbrugger. In any such series of essays it 

 becomes necessary for the writer to form some 

 such estimate of the relative importance of the 

 life-work of each man and here doubtless 

 many would diiler from Dr. Walsh in some 

 respects; but as far as he allows himself to 

 discuss this, he is fair and his estimates well 

 weighed. 



The papers were written and published 

 separately at intervals and later put together 

 into book form, and this results in a good deal 

 of repetition of monotonous discussion as 

 well as of incident and quotation, but on the 

 whole for the purpose for which they are 

 aimed, the general instruction of the public 

 in matters pertaining to medical history, they 

 are, like the similar essays of Eichardson, ex- 

 tremely entertaining and useful.

SCIENTIFIO JOURNALS AND ARTICLES 

 The American Naturalist for July opens 

 with a note on the " Agassiz Centennial," be- 

 ing the remarks of Charles W. Eliot. These 

 remarks, being brief and to the point, and 

 couched in smooth English give a much better 

 idea of the charm of Agassiz and the great 

 influence of his personality than do most of 

 the longer articles that have appeared. A. W. 

 Morrill gives a " Description of a New Species 

 of Telenomus with Observations on its Habits 

 and Life History," the species being named 

 Telenomus ashmeadi. Frederic T. Lewis dis- 

 cusses " The Development of Pinnate Leaves " 

 and D. P. Penhallow makes some " Contribu- 

 tions to [our knowledge of] the Pleistocene 

 Flora of Canada," based on leaves from the 

 interglacial deposits of the Don Valley,
