“ Arr. IX.—Nolice of the Zoological Writings of the late C. S. 
Rafinesque ; by S. 8. Hatpeman.* 
Constantine SamveL Rarinesqure, was born “at Galata, a sub- 
urb of Constantinople,” October 22d, 1783, and died in Phila- 
delphia on the 18th of September, 1840, of cancer of the stomach 
and liver. While yet an infant, his parents removed to Marseilles, 
where he remained some years, previous to being removed to Leg- 
horn. It is apparent throughout his works, that he considers him- 
self a great traveller; thus the motto to his “ Life of Travels” is 
‘Un voyageur dés le berceau, 
Je le serais jusqu’au tombeau.”’ 
He states that his parents took him to Asia while he was an 
infant, that he saw the coast of Africa, and names the places he 
would have seen, if he had been allowed to accompany his father 
to Canton! According to his own account, he commenced the 
study of natural history at an early age, which is certainly the 
fact, as his “description of four new species of birds from Java,” 
(seen in the Philadelphia museum, ) was published in the Bul. des 
Sciences in 1803, when he was but nineteen years old; and his 
Florula Columbica and Delawarica, were presented to Dr. Barton, 
for insertion in his Med. and Phys. Journal, the year following.
