of natnr.il history and botany in the .Sonth CaroHna Medical College, 

 which he aided to establish. He ])ublished the Botany of vSouth Caro- 

 lina and Geor.s^ia (Charleston, 1821-1827), havint;" been assisted in its 

 l>reparation by Doctor James McBride; and had an extensive museum of 

 his own ,g:athering-. The Elliott vSociet>- of Natural History, founded 

 in 1S53, or ])efore, and snbsequentl}' continued under the name of the 

 h-lliott vSociety of vScience and Art, 1^59-1875, was named in memory of 

 this public-spirited man. 



Jacob Green [b. 1790, d. 1S41], at different times profes.sor in the 

 College of New Jersey and in Jefferson Medical College, was one of the 

 old .school naturalists, equally at home in all of the sciences. His j^aper 

 on Trilobites (1832) was our fir.st formal contril)Ution to invertebrate 

 paleontolog}-; his Account of some new Species of vSalamanders,' one of the 

 earliest steps in American herpetology; his Remarks on the TTnios of the 

 United vStates," the l)eginning of studies subse([Uenth' exteusivel\' ])ro.se- 

 cuted by Lea and .some other entomologi.sts. He also wrote U])on the 

 cr^'.stalli/.ation of snow, and was the author of Chemical Philo.sophy, 

 Astronomical Researches, and a work upon Botany of the United vStates. 



The earlier volumes of vSilliman's Journal were filled with notes of his 

 observations in all departments of natural hi.story. 



Jose Francisco Correa da vSerra, .secretary of the Royal Academy of 

 lyi.sbon, was resident in Philadelphia in 18 13, in the capacity of Portu- 

 guese minister, and affiliated with our men of science in botanical and 

 geological interests. In 18 14 he lectured on botany in the place of B. vS. 

 Barton, and also published several bcAanical papers, as well as one upon 

 the .soil of Kentucky. 



Alire Raffenau Delile, formerly a member of Napoleon's scientific 

 exi)edition to Egypt and the editor of the Flora of Egypt, was in 

 New York about this time, for the purpo.se of completing his medical 

 education, and .seems to have done nuich to stinuilate interest in botan- 

 ical .studies. 



To this as well as to the sul)sec|uent period l)elonged Doctor (icrard 

 Troost [b. in Holland, March 15, 1776: educated in Leyden; d. in Nash- 

 ville, August 17, 1850], a naturalist of Dutch l)irth and education, who 

 came to Philadelphia in 18 10, and was a founder and the first president of 

 the Pliiladelphia Academy. In 1826 he founded a geological survey 

 of the environs of Philadel])hia ; in 1827 became professor of chemistry, 

 mineralogy, and geology in the University of Na.shville. As vState geol- 

 ogist of Tennessee from 1831 to 1849 he published some of the earliest 

 State geological reports. 



Another expedition well worthy of mention, though not exceedingly 

 fruitful, was one made under the direction of Mr. Maclure, president of 

 the Philadelphia Academy, to the sea islands of Georgia and the Florida
