The earliest contribution on what may be broadly termed 

 "Animal Psychology" appeared about 1883, in the Journal of 

 Morphology a brief treatise on mental powers of spiders. 

 This was followed by several minor contributions in the publi- 

 cations of the Wisconsin Natural History Society, on both 

 wasps and spiders, a larger treatise on Sexual Selection and

 a classic of, at least, the psychological phase of animal study. 



Before this, scientific recognition had come to Dr. Peckham

 and Letters ; in 1896, the University of Wisconsin honored him 

 with the degree of Doctor of Laws.

 life. To this he sacrificed the careers of lawyer and physician ; 

 to this he sacrificed his vacations and what leisure hours he 

 could spare from his arduous duties. Dr. Peckham, as the 

 writer knew him, was a small man, somewhat bent with age, 

 rheumatism and the close application necessitated by his my- 

 opia. The scholarly stoop, the silvery white hair, and the mod- 

 erate gait impressed everyone as attributes of a man who has 

 made his mark on the world. On public or semi-public occa- 

 sions the thoroughness and breadth of Dr. Peckham's infor-
