Klem—Thé History of Science in St. Louis. 119 
which bears the name of Engelmann, will still, it is to be 
hoped, cover with noble forests the highest slopes of the 
Rocky 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 Rocky 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 cireumstances—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,** 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
