4l8 Memorial of George Brown Goode. 



at Lancaster, was an eminent botanist, edncated in Germany, though a 

 native of Penns34vania. His Flora of Lancaster was a pioneer work. 

 In 1813 he pubhshed a full catalogue of the plants of North America, in 

 which about 2,800 species were mentioned. He supplied Hedwig with 

 many of the rare American mosses, which were published either in the 

 Stirpes Cryptogamicae of that author or in the Species Muscorum. To 

 Sir J. E. Smith and Mr. Dawson Turner he likewise sent many plants. 

 He made extensive preparations, writing a general flora of North America, 

 but death interfered with his project. The American Philosophical 

 Society preserves his herbarium, and the moss Fiineria muhlenbergii^ 

 the violet Viola muJilenbergii, and the grass MzMenbergia are among 

 the memorials to his name.' 



To Pennsj'lvania, but not to Philadelphia, came in 1794 Joseph Priest- 

 ley [1733-1804], the philosopher, theologian, and chemist. Although 

 his name is more famous in the history of chemistry than that of any liv- 

 ing contemporary, American or European, his work was nearly finished 

 before he left England. He never entered into the .scientific life of the 

 country which he sought as an exile, and of which he never became a 

 citizen, and he is not properly to be considered an element in the history 

 of American science. 



His coming, however, was an event of considerable political impor- 

 tance, and William Cobbett's Observations on the Emigration of Doctor 

 Joseph Priestley, by Peter Porcupine, was followed by several other pam- 

 phlets equally vigorous in expression. McMaster is evidently unjust to 

 some of the public men who welcomed Priestley to America, though no 

 one will deny that there were unprincipled demagogues in America in 

 the year of grace 1794. Jefferson was undoubtedly sincere when he 

 wrote to him the words quoted elsewhere in this address. 



Another eminent exile welcomed by Jefferson, and the writer, at the 

 President's request, of a work on national education in the United States, 

 was M. Pierre Samuel Dupont de Nemours [b. in Paris, 1739; d. 1817]. 

 He was a member of the Institute of France, a .statesman, diplomatist, 

 and political economist, and author of many important works. He lived 

 in the United States at various times from 1799 till 18 17, when he died 

 near Wilmington, Delaware. Like Priestley, he was a member of the 

 American Philosophical vSociety, and affiliated with its leading members. 



The gunpowder works near Wilmington, Delaware, founded by his 

 son in 1798, are still of great importance, and the statue of one of his 

 grandsons, an Admiral in the United States Navy, adorns one of the 

 principal sc[uares in the national capital. 



Among other notable names on the roll of the society in the la^t cen- 

 tury were those of General Anthony Wayne and Thomas Payne. His 

 Excellency General Washington was also an active member, and .seems
