THE INCORPORATORS 131 
In later life Dr. Engelmann visited the mountain region of 
North Carolina and Tennessee, the Lake Superior region, the 
Rocky Mountains and the Pacific Coast, seeing for the first time 
in the native haunts many species of plants he had studied before 
from dried specimens, and adding to the great collections already 
made. 
He was deeply interested in the land of his adoption and 
showed his devotion to its scientific welfare by his efforts in the 
founding of the St. Louis Academy of Science, of which he was 
16 times elected President. He also delivered courses of lectures 
at Washington University, an institution in which he took great 
interest. In return, many marks of appreciation were given him, 
preéminently in the generosity of Mr. Shaw and others in collect- 
ing and republishing all his botanical works. His entire herba- 
rium, comprising 100,000 specimens, and his library, including 
his notes and botanical sketches, have since been given by his son 
to the Missouri Botanical Garden, sometimes known as the 
Shaw Garden. 
Crushed in spirit by the death of his wife and the illness of 
his son, in 1879 Dr. Engelmann’s health was seriously impaired, 
but accepting Professor Sargent’s invitation to accompany him 
to the forests of the Pacific Coast he gradually regained his 
spirit of cheerfulness, and though the journey was an arduous 
one for a man of his age he once more took up his work. In 1883 
he revisited Europe, but soon after his return succumbed to the 
disease that had fastened itself upon him, and died February 4, 
1884. 
Dr. Engelmann’s last publication was his meteorological work 
—the result of his observations for 47 years. 
His botanical work was very extensive, the notes made in the 
examination of specimens amounting to 20,000 slips, constituting 
60 quarto volumes. His studies of the cactus family, of the 
yucca and the agave, of the American oaks and conifers, and of 
North American vines, show marks of his indomitable energy 
and patience. His endurance as a traveller was remarkable.
