1 64 POPULAR SCIENCE MONTHLY. 



I have included among the American titles those published in 

 Europe by residents of America, except when there was reason to be- 

 lieve that they might have been prepared during visits to Europe. I 

 have included papers published in Canada, and one or two from Mexico, 

 but if these were deducted they would not (except in the case of the 

 sponges) materially affect the result. Of course it must be acknowl- 

 edged that the titles indicate contributions of every size and degree of 

 merit; but as I have looked them over, it has seemed to me that ours 

 were not inferior in quality or size to those of other countries. 



The editor of the Popular Science Monthly (March, p. 476) has 

 justly remarked that we ought not to expect to equal the rest of the 

 world in our product ; and in his opinion if we contribute one seventh 

 we are doing our share. It will be seen from the above list that we 

 actually are contributing approximately this amount in most of the 

 divisions of zoology, while in some groups the proportion is greater. 

 This conclusion agrees well with the impression gained by the writer 

 through his experience of zoology and zoologists both in England 

 and America. 



It may be worth while to add some particulars regarding the 

 workers who represent zoology in America to-day. 



General Subject. The list for 1900 includes 82 workers, and the names 

 of Alexander Agassiz, Calvert, Davenport, B. Dean, Eigenniann, Eisen, Gill, 

 Hyatt, Kingsley, Loeb, Minot, H. F. Osborn, Peckham, Pilsbry and Wilson 

 are as familiar to European zoologists as they are to us. Many of the papers 

 both here and in other groups are the work of the great body of University 

 students, prepared under the guidance of leading zoologists, of whom C. B. 

 Davenport, of Chicago, is especially conspicuous for his large following. 



Mammalia. 26 workers, of whom J. A. Allen, D. G. Elliott, C. H. Mer- 

 riam and H. F. Osborn are perhaps the most widely known. The study of the 

 mammals in this country is being carried on with a zeal and industry which 

 finds no parallel in any previous period; and the careful investigation of the 

 geographical races is giving us material of the greatest value in the study of 

 evolution. The credit for this revival is mainly due to Merriam; and the 

 Europeans, who at first ridiculed his methods, are beginning to follow in his 

 footsteps. American mammalogists have also begun to compete vigorously with 

 Europeans in the study of old-world mammals, and G. S. Miller has even 

 described a number of new ones from Europe. 



Birds. 66 workers, including J. A. Allen, F. M. Chapman, E. Coues (now 

 dead), R. Ridgway, R. W. Shufeldt and many others well-known in both 

 hemispheres. We have a first-class journal (The Auk) devoted to birds, to- 

 gether with a number of minor ones. 



Reptiles and, Batrachia. 29 workers; the titles including the great work 

 on North American reptiles by the late E. D. Cope. Our principal writer now 

 living is Stejneger of the National Museum. 



Fishes. 22 writers; the titles include a part of the great work on the 

 fishes of North America, by Jordan and Evermann. The American fishes have 

 been and are being very thoroughly studied; and Dr. Jordan, with several 

 helpers, is making known the fish-faunae of Japan and the Hawaiian Islands.
