Additional Notes. 5 1 1 



Father Plumier was one of the first good writers on the 

 Ferns. His Traitc des Fougeres de f* Ameriiiue, published 

 in 1705, holds a high rank among the works on this part of 

 botany. 



The work of the Marquis de St. Si]\ion, on Hi/acinihs, 

 (4to. Amsterdam, 1786) is worthy of respectful notice. 



Before the work of M. C. Heretier, on the Geranium^ 

 Professor Burman, of Amsterdam, had written ably on that 

 extensive family of plants. 



Mr. Ellis, of Great-Britain, (the celebrated writer on 

 Corallines) has given the best botanical account of the coffee- 

 tree that is extant. 



Academic Dissertations on Botanical Subjects, p. 140. 



At the close of the eighteenth century, only five disserta- 

 tions, it is believed, had been published by the medical gra- 

 duates of America on botanical subjects. These are respect- 

 fully noticed in the above-mentioned page. Since that time, 

 publications of this kind have considerably multiplied. The 

 learned and interesting lectures on botany, delivered by Profes- 

 sor Barton, of tlie University of Pennsylvania, and his en- 

 lightened zeal in pursuing this branch of science, have pro- 

 duced a very sensible effect in recommending it to the atten- 

 tion of the students in that seminary. In the course of the 

 last three years, the following dissertations on botanical sub- 

 jects have been added to the former small list. 



1. On the Digitalis Purpurea, by John Moore, of Penn- 



sylvania. 



2. On the Kalmia Latifolia and Angustifolia, by George 



Thomas, of Virginia.

Maryland.
