James E. Smith, president of the Linnean Society, who be- 
came a life-long friend. 
On his return to New York, Dr. Hosack took with him the 
first considerable cabinet of minerals brought to this country, 
and also duplicates of the herbarium of Linnaeus, afterwards 
given by him to the Lyceum of Natural History, but since 
destroyed by fire. 
In 1795 he was made professor of botany in Columbia 
College, and in 1797, of materia medica also, which chairs he 
retained until 1811, when he resigned, on being made pro- 
fessor of materra medica and clinical medicine in the College 
of Physicians and Surgeons, which he held until 1826.* In 
that year he, with Dr. Mott, Dr. Francis and others, resigned, 
through dissatisfaction with the government of that institution, 
and formed the Rutgers Medical College, with Dr. Hosack as 
president of the faculty.t The new school was very pros- 
perous until the state interfered in 1830 and gave such advan- 
tages to the College of Physicians and Surgeons as caused 
Rutgers to be abandoned, though without immediate advan- 
tages to its older competitor.{ Dr. Hosack did not afterwards 
engage in public instruction. He died December 23, 1835, 
from apoplexy caused by exposure to extreme cold. 
The above engagements form but a small part of Dr. 
Hosack’s activities. In 1796 he became a partner of Dr. 
Samuel Bard, who in 1798 retired to the country at Hyde 
Park § (where Dr. Hosack afterwards had a summer resi- 
dence), leaving Dr. Hosack in the enjoyment of a large and 
lucrative practice. He became, says Dr. Francis, for thirty 
years the leading practitioner of histime. For twenty years 
he was one of the physicians of the New York Hospital. He 
attended Hamilton at his fatal meeting with Burr, July 11, 
1804, and the following day until his death.
