which bears the name of Engelmann, will still, it is to be 

 hoped, cover with noble forests the highest slopes of the 

 Eocky Mountains, recalling to men, as long as the study 

 of trees occupies their thoughts, the memory of a pure, 

 upright, and laborious life." 



Associated with Dr. Engelmann in the earlier years of 

 his career in St. Louis was Dr. Adolphus Wislizenus, 

 whose name will ever be honorably associated with the 

 history of science in St. Louis. Although Dr. Wislizenus 

 had settled in St. Louis to practice medicine, scientific 

 exploration lured him on two extensive expeditions — one 

 in 1839 to the Eocky Mountains and the other in 1845 to 

 northern Mexico. The results of his Mexican tour will 

 be regarded as his most valuable contribution to science, 

 having been publicly acknowledged by Humboldt as of 

 value to him in his studies of that region. 



Among some of the many other distinguished members 

 of the Academy of Science, whose memories we honor 

 and cherish and to whom we are indebted for liberal con- 

 tributions to knowledge — often acquired under the most 

 trying circumstances — are Hiram A. Prout, to whom is 

 justly due the credit of having first called attention to the 

 existence of the gigantic extinct remains in the Bad 

 Lands of Nebraska by his excellent memoir on Palaeo- 

 theroid and other bones, and for whom the Titanotherium 

 Proutii will stand as a lasting monument in the world of 

 science ; James B. Eads, 45 who devised and furnished our 

 Government with its first and most useful armored steam- 

 boats, who constructed the bridge spanning the Missis- 

 sippi at St. Louis which bears his name, and who by 

 means of jetties at the mouth of the Mississippi opened
