appear as joint author, and that it should be quoted as Schweinitz 

 & Torrey. 



Foreseeing that the Linnaean system was to be supplanted by 

 one founded upon a more profound knowledge of the structure of 

 plants and broader vLws of their relationships, the Flora was not 

 continued beyond its first volume, but its author, in 1826, published 

 a Compendium which contained condensed descriptions of the 

 plants enumerated in the first volume of the Flora and of those 

 that would have been given in the second volume. 



In 1826, Dr. Torrey read before the Lyceum " Some Account 

 of a Collection of Plants made during a Journey to and from the 

 Rocky Mountains, in the Summer of 1820, by Edwin P. James, 

 M.D., Assistant Surgeon, U. S. Army." This memoir was not 

 published until 1828. Before its publication its author, after three 

 years 1 service, left West Point to assume the chair of Chemistry 

 and Botany in the N. Y. College of Physicians and Surgeons. 

 This account of Dr. James's Rocky Mountain plants is of especial 

 interest as being the first botanical publication of importance in 

 this country in which the plants were arranged according to the 

 Natural System. Shortly before, the Abbe Correa had arranged a 

 list, in which the genera named in Muhlenberg's catalogue were 

 placed according to the system of Jussieu. 



In 1831, Lindley's introduction to Botany was re-published in 

 this country. Dr. Torrey prepared a catalogue of the North 

 American genera, arranged according to Lindley's orders, which 

 was published with the work and also separately in the pamphlet 

 form. 



Dr. Torrey was always fond of studying obscure and difficult 

 orders, hence the Borraginacese, Chenopodiacea?, Amarantaceae, 

 and Cyperacete had particular attractions for him. As early as 

 1836 he published in the Annals of the Lyceum his " Monograph 

 of the Cyperaeese." This contained, besides a full account of the 

 other genera, a complete revision of the genus Carex, and was a 

 most valuable contribution to North American botany, as it con- 

 tained an elaboration of the species collected by Drummond, Rich- 

 ardson, Burke, aud other British collectors, whose specimens were 

 loaned by Sir William Hooker. 



The Geological Survey of the State of New York was organ- 

 ized in 1836, and Dr. Torrey was appointed as its Botanist. His 

 report, which was published in 1843, forms two enormous 4to vol- 

 umes, filled with detailed descriptions of all the plants known to 

 belong to the State, and is illustrated with 161 plates. When we 

 consider that this work was produced amid the labors of his pro- 

 fessorship at the Medical College, to which had been added those 

 of the Chair of Chemistry at Princeton, we must wonder at the un- 

 tiring industry of its author. 



The first number of the " Flora of North America, by John 

 Torrey and Asa Gray," appeared in 1838, the fruit of a most happy
