CHESTER DEWEY:.! 
PROFESSOR CHESTER DeEwery died at Rochester, New 
York, December 18, having completed the eighty-third year 
of his age. ‘ He was born at Sheffield, Massachusetts, Oc- 
tober 25, 1784; was graduated at Williams College in 1806 ; 
studied for the ministry ; was licensed to preach in 1808, 
and during the latter half of that year officiated in Tyring- 
ham in western Massachusetts. The same year he accepted 
a tutorship in Williams College, and in 1810 was appointed 
professor of mathematics and natural philosophy, an office 
which he discharged for seventeen years. During his con- 
nection with the college he did much to advance the standard 
of scholarship and enlarge the course of study in his own and 
kindred departments. Between 1827 and 1836 he was prin- 
cipal of the ‘Gymnasium,’ a high school for boys at Pitts- 
field, Massachusetts. In the latter year he removed to this 
city (Rochester), and became principal of the Rochester 
Collegiate Institute, which post he held until 1850, when he 
was elected professor of chemistry and natural philosophy in 
the Rochester University. He was actively engaged in the 
duties of that position till 1860, when he retired at the age of 
seventy-seven, though he continued to teach to some extent 
till his eightieth year. The last four years he has passed in 
easy and dignified retirement, happy in the society of his fam- 
ily and friends, beloved and respected by all, and occupying 
himself still with his scientific studies and with meteorological 
observations, which he conducted with great care and regu- 
larity.”
