On his death in 1834, Schweinitz bequeathed to the Academy 

 of Natural Sciences, Phila., his great collection, made during a 

 period of forty years. 



This herbarium contained, besides the Cryptogamous plants, 

 23,000 species. It remains at this day, almost fifty years later, 

 the largest personal collection among the 90,000 species repre- 

 sented in what Dr. Darlington termed "one of the richest and most 

 valuable herbaria in the United States." 



Schweinitz laid all his scientific friends under tribute to gath- 

 er together this magnificent collection. Most of the American 

 species were collected by himself; but many were supplied by Dr. 

 Torrey,M. LeConte, Rev. Mr. Dencke, Mr. J. Elliot, Mr. H. Stein- 

 aur, and other correspondents. The European species were sup- 

 plied by Mr. Van Welden,Dr. Hooker, Mr. Bentham, Dr. Schwar- 

 grichen,Dr. Stendel, Dr. Zeyher and Mr. Bronguiart. The Siberian 

 plants were furnished by Mr. Ledebuur, and those of India by 

 Dr. AVallich and Mr. H. Steinhaur. The Chinese ccdlection was 

 made by Mr. Jas. Read. The plants of the polar region were 

 collected by Captain Parry and presented by Dr. Hooker; an in- 

 teresting col'ection from Labrador was added by Mr. Kohlmeister, 

 a Moravian missionary of that country. The South American 

 species were obtained chiefly through M. Von Martins, Dr. Huffel 

 and Dr. Constantine Hering. Dr. Baldwin contributed 3,000 

 species of plants collected by himself in Buenos Ayres, Florida and 

 other parts of North America. 



KUTTALL. 



Dr. Thomas Nuttall, an ardent and distinguished American 

 botanist, whose collections also remain to us in the Phila. Acad- 

 emy of Sciences, was born in Yorkshire, England in 1786. and died 

 in St. Helens, Lancashire, September 10th, 1859, being 73 years of 

 age. His trade was that of a printer, but early in life he came to 

 the U. S. as a student of natural history, and especially of botany 

 and geology.
