The American Naturalist 



Was commenced twenty-two years ago, by an association of the students of Prof. Agassiz, 

 at Cambridge. While it has followed the fortunes of its founders from comparative youth to a 

 vigorous maturity, it lias gathered to its support most of the biologists and geologists of North 

 America. 



Its constituency of authors includes a majority of the men of this class in the country. 



The proprietors have associated with Professors Cope and Kingsley, its principal editors, a 

 number of leading scientists, whose names are a guarantee of editorial ability. 



Dr. C. W. Whitman, of Milwaukee, one of our ablest histologists, directs the department of 

 Microscopic technique. 



Prof. W. T. Sedgwick, late of Johns Hopkins University, now of the School of Technology, 

 Boston, has charge of Physiology. 



Prof. C. E. Bessey, of the University of Nebraska, edits the Botanical department. 



The division of Anthropology is under direction of Mr. Thomas Wilson, whose connection 

 with the Smithsonian Institution, Washington, D. C, gives him exceptional facilities. 



Prof. J. H. Comstock, the able Professor of Entomology of Cornell University, sustains 

 both pure and economic Entomology. 



Prof. W. S. Bayley, of the University of Wisconsin, has charge of Mineralogy. 



Mr. W. N. Lockington, naturalist and man of letters, of Philadelphia, furnishes the best, 

 and indeed the only abstract of the results of Geographical Explorations of the World that is 

 published on this Continent. 



Prof. J. A. Ryder, of the University of Pennsylvania, edits the department of Embryology, 

 a subject of which he is a well-known master.

AND MANY OTHEBS. 



It has been the aim of the Naturalist to preserve its well-known national character, 

 which is illustrated in the wide distribution of its editorial responsibilities. 



It appears to be the most favored medium of publication of the naturalists and biologists 

 in the United States when they wish to bring the results of their investigation before the gen- 

 eral public in a more or less popular form. It is the only magazine in the world to-day 

 which keeps its readers en rapport with the works of Americans in the field of the natural 

 Sciences. The NATURALIST publishes 96 large octavo pages per mouth, with numerous illus- 

 trations. 



Terms, $4.00 per year; 40 cents per number.
