THE PROGRESS OF ZOOLOGY 479 



now living who will no doubt in the next generation be ranked 

 with those mentioned in the preceding paragraphs. These 

 men, their associates, and their students are all engaged in add- 

 ing to the sum of human knowledge so far as animals are con- 

 cerned. They are for the most part at work in universities, 

 museums, endowed institutions, or government institutions. 



The professors in nearly all universities are encouraged not 

 only to distribute knowledge by teaching, but also to add to our 

 knowledge by carrying on original investigations. The results 

 of these investigations are published in scientific magazines 

 such as the Journal' of Morphology, the Journal of Experimental 

 Zoology, the Biological Bulletin, the American Naturalist in 

 this country and in the many foreign magazines of a similar 

 nature. 



Natural history museums are often considered simply places 

 where stuffed animals are exhibited, but the best museums em- 

 ploy capable scientists who spend all of their time working over 

 the collections and publishing the results of their researches. 

 Some of the large museums in this country are the National 

 Museum in Washington, D.C., the Museum of Comparative 

 Zoology in Cambridge, Massachusetts, the American Museum 

 of Natural History in New York City, the Philadelphia Academy 

 of Sciences in Philadelphia, Pennsylvania, the Carnegie Museum 

 in Pittsburgh, Pennsylvania, and the Field Museum in Chicago, 

 Illinois. 



There are very few endowed institutions for the advancement 

 of science, but those that have been established within recent 

 years in this country have accomplished a great deal for the 

 progress of science, both pure and applied. The largest of these 

 are the Carnegie Institution in Washington, D.C., and the 

 Rockefeller Institute in Brooklyn, New York. 



The meeting place of the sea and land is especially rich in 

 the number of animals that have selected it as a habitat. It is 

 not strange therefore to find zoologists studying at the seashore. 

 There are several laboratories on our eastern coast and several
