158 THE BOTANISTS OF PHILADELPHIA. 



His death occurred on September 10, 1859. In opening 

 a case of plants received shortly before from Mr. Booth he 

 overstrained himself, and from that time steadily declined 

 until his death on September 10, 1859. His love of nature 

 was great, and this, joined with untiring industry and great 

 firmness of purpose, had raised him from the position of an 

 unknown artisan to the foremost rank of American men of 

 science. Elias Durand said of him immediately after his 

 death : " No other explorer of the botany of North America 

 has personally made more discoveries ; no writer on American 

 plants, except perhaps Prof. Asa Gray, has described more 

 new genera and species." His name is memorialized in a 

 genus of rosaceous plants, Nuttallia.
