soon made it over to Columbia College. In 1810 he made a 

 voyage to the West Indies for the recovery of his health. 

 Returning in the autumn of 1811, he landed at Wiscasset,

The plants collected by Lewis and Clark, on their 

 return from the far West, were studied, described, and 

 figured by Pursh. He inserted the descriptions in his flora, 

 distinguishing them by the words : " v. s. in Herb. Lewis."

 Enslen, sent to America by Count Lich ten stein, of Austria, 

 which fitted up a desideratum in his collection, particularly 

 in the plants of Lower Louisiana and Georgia. " v. s. in Herb

 seeing the herbarium and collection of living plants of Mr. 

 John Lyon, a gentleman, through whose industry and skill,

 Plukenet, Catesby, Morison, Sherard, Walter, and that of 

 Banks.*
