Dr. T. Wesley Mills 459 



Book on Comparative Physiology," in 1890. His next 

 publication was on "How to Keep a Dog in the City," 

 in 1891, and this was succeeded by a volume on "The 

 Dog in Health and Sickness, ' ' in 1892. No one was ever 

 a greater lover of dogs than he and no one ever got 

 deeper into the secrets of the dog's nature. Indeed, he 

 was known as the friend and champion protector of all 

 animals. An ancient poet-philosopher took credit to 

 himself that he counted nothing relating to man foreign 

 to him. The range of Professor Mills' interest and 

 sympathies Avas vastly more comprehensive : it em- 

 braced everything that had life. To him no bird or beast 

 was an object of indifference. And this is a prime 

 qualification in one who would interpret animal life. 

 To understand the creatures about us we must love 

 them, as love is the true organ of man's perception and 

 of his interpretation of the entire field of his observa- 

 tions. Longfellow ascribes the remarkable skill in vari- 

 ous kinds of woodcraft of his Indian hero, Hiawatha, to 

 the tenderness of his sympathies with the tenants of the 

 forest ; in consequence they readily yielded up their 

 secrets to him: He "learned of every bird its language, 

 where they built their nests in summer, where they hid 

 themselves in winter. ' ' According to this law, while the 

 knowledge of that most sagacious animal and companion 

 of man, the dog, Dr. Wesley Mills made peculiarly his 

 own, all animal nature was to him an open book. 



When he entered upon the domain of Comparative 

 Physiology, he extended the scope of his energies and 

 thought, and the fruit of his new studies was given in his 

 next publication, "The Nature and Development of 

 Animal Intelligence," a work of rare charm, issued in 

 1898. Speculation along the line of evolution was rife 

 at this time, and Dr. Mills' work gave tokens that he had 

 come largely under the fascinating spell of Darwin, 

 Huxley, Spenser, and Hasckel. These great masters had 

 an unquestioned influence upon his views. His studies 

 were conducted under the same thorough fashion as
