differences of temperatures and humidity in the city and 

 in Shaw's Garden (which was, he said, on an open prairie 

 three miles from the city) Dr. Nipher concluded with the 

 statements that Engelmann was continuously in co-oper- 

 ation with the weather service in charge of the Smith- 

 sonian Institution, and that in many ways his aid was 

 solicited hy government officials in charge of work in the 

 far west. 



Professor Trelease, of the Missouri Botanical Garden, 

 which possesses Engelmann 's invaluable collections, con- 

 cluded the program with a paper on ''Engelmann as a 

 Biologist." He showed a number of drawings which 

 exhibited Engelmann 's skill in picturing details of plant 

 structure, among them those made for his thesis, which 

 was published in 1828, as well as the large quarto volume 

 in which his botanical publications were reprinted at the 

 expense of Henry Shaw in 1887, under the editorial direc- 

 tion of the great botanist, Asa Gray of Harvard Univer- 

 sity. To these were joined specimens of the beautiful 

 prairie flower named Engelmann in his honor, and of the 

 blue spruce of Colorado, which also bears his name. 

 Tersely epitomizing Engelmann 's work, and analyzing 

 the economy* of time and directness of purpose which 

 enabled him to accomplish in the leisure hours of a busy 

 physician's life more than the average achievement of 

 a botanist whose whole effort is directed to his specialty, 

 Professor Trelease closed by quoting from Engelmann 's 

 gifted biographer. Professor Sargent of Harvard Uni- 

 versity, the prediction that the western plains will still 

 be bright with the yellow rays of Engelmannia, and that 

 the splendid spruce will still cover with noble forests 

 the highest slopes of the Rocky Mountains, recalling to 

 men, as long as the study of botany will occupy their 

 thought, the memory of a pure, upright, laborious and 

 stimulating life. 



At the conclusion of the memorial session, the mem- 

 bers and guests of the Academy were invited to pass into 

 another room, where were displayed a number of inter- 

 esting objects connected with or commemorative of En- 

 gelmann 's life and work. Under the guidance of Mr. 

 H. C. Irish and Mr. Charles H. Thompson, who explained
