Mr. Nipher made additional remarks, as follows: 



Dr. George Engelmann, for many years the honored President of this 

 Academy, died February 4th, aged 75 years. Dr. Engelmann's earliest 

 publications were made in 1832, and consisted of two small volumes. In 

 1837 he made extended tours through Missouri, Arkansas, Kansas, Indian 

 Territory, and New Mexico. At this time he also began his temperature 

 and rainfall record, which, with the exception of a few gaps when absent 

 from the city, he continued down to within a few days of his death. His 

 last report, on the meteorology of January, was made out after all hope of 

 life had been abandoned by his physicians. 



In 1843 ^^ accompanied the party which made the survey of the Mexi- 

 can boundary, and this field work occupied him two years. The results 

 of his investigations were published in a large work by the Government in 

 a report entitled, *'A Description of the Cactacea of the Boundary," with 

 seventy-six plates. 



Then for several years an extensive practice in his profession absorbed 

 the greater part of his time, but his interest in scientific work did not flag. 

 In 1842 he had already published a paper, illustrated by a plate, in volume 

 xliii. (1842) of Silliman's Journal, on the genus Cuscuta, which attracted 

 general attention, and was republished in Hooker's Journal of Botany, 2d 

 volume, 1843. He continued his investigations in this genus, and finally 

 published in our Transactions an elaborate paper entitled "Systemic 

 Arrangement of the Species of the Genus Cuscuta, with Critical Remarks 

 on Old Species and Descriptions of New Ones." The materials for this 

 paper were drawn from various expeditions in the West, and from many 

 American collections, in addition to the vast material placed at his dis- 

 posal by the directors of the great collections in London, Paris, Berlin, 

 Vienna, and Geneva. 



Other important papers were: "Additions to the Cactus Flora of the 

 United States"; " On Pinus aristata and other Rocky Mountain Pines"; 

 "A Revision of the North American Species of the Genus Juncus., with 

 Descriptions of New or imperfectly known Species"; "Notes on the Genus 

 Yuccd"\ "Notes on Agave"\ "On the Oaks of the United States"; "The
