in anatomy in 1805, was active in establishing the reading-room that was developed into the Boston athenaeum, and formed a private medical society. In 1806 he was chosen adjunct professor in anato- my and surgery in Harvard, In 1810 he assisted in founding a hospital for the destitute, and in 1811 the "New England Journal of Medicine and Surgery." In 1815 he was appointed professor of anatomy and surgery in Harvard. He was one of the founders of the Massachusetts general hospital in 1820, and principal surgeon until his death. In 1827 he was elected president of the Boston tem- perance society. He exercised great caution in performing surgical operations, many of which were hitherto unknown in the United States, and he was almost invariably successful. He was the first to operate for strangulated hernia, and even- tually his method was adopted. He introduced the operation for aneurism, and performed it in numerous cases, all of which were successful except two. In 1837 he went to Europe for further study. After his return he became an active member of the Agricultural society of Massachusetts, and im- proved the breed of cattle by importation of for- eign stock. He was also chosen president of the Society of natural history. In 1845 he obtained the most perfect skeleton of the mastodon that ex- ists. In 1846 he gave a new impulse to operative surgery by the introduction of ether, and his ad- vocacy of its use in certain cases led to its general adoption by the profession. Besides frequent con- tributions to scientific journals, Dr. Warren pub- lished " Cases of Organic Diseases of the Heart " (Boston, 1809) ; " Description of an Egyptian Mum- my "(1821); " Comparative View of the Sensorial and Nervous Systems in Man and Animals " (1822) ; " Some Account of the Medical School in Boston, and of the Massachusetts General Hospital " (1824) ; " Letter to Hon.

WARREN, Joseph, journalist, b. in Water-
bury, Vt., 24 July, 1829 ; d. in Buffalo, N. Y., 30
Sept., 1876. He studied at the University of Ver-
mont, and soon afterward went to Albany, N. Y.,
where he was made assistant editor of the " Coun-
try Gentleman " in 1849, and also teacher of Latin
and Greek at the Albany academy. He became
associate editor of the Buffalo " Courier " in 1853
and editor-in-chief in 1858, and was chosen presi-
dent of the New York press association in 1870.
He was a member at large of the Democratic state
central committee, and a leader of his party in
western New York. He was elected superintend-
ent of public schools in Buffalo in 1857, advocated
a public park system for that city, and served
on the park commission from its formation in
1871 till his death. He was instrumental in secur-
ing the establishment of the State insane asylum
and the State normal school in Buffalo, took an
active part in the organization of the Fine-arts
academy, and was interested in the project of the
Buffalo, New York, and Philadelphia railroad. He
was at one time president of the Young men's
Christian association, and was a member of the
council of the medical department of the Uni-
versity of Buffalo.
WARREN, Josiah, reformer, b. in 1799 : d. in
Boston, Mass., 14 April, 1874. He took an active
part in Robert Owen's communistic experiment
at New Harmony, Ind., in 1825-'6, and was so dis-
couraged by its failure that he was on the point
of abandoning any further attempt in that direc-
tion when, as he said, " a new train of thought
seemed to throw a sudden flash of light upon our
past errors, and to show plainly the path to be
pursued." He forthwith gave up the idea of main-
taining a communal system of society, and sought
to attain the same ends through individual sover-
eignty. He held that the proper reward of labor
was a like amount of labor, and elucidated his
theory by a supposition. " If I am a bricklayer,
and need the services of a physician, an hour of
my work in bricklaying is the proper recompense
to be given the physician for an hour of his ser-
vices." He proved the sincerity of his belief in this
idea by establishing. what was known as the " time
store" in Cincinnati, Ohio, which he conducted
with fair success for two years, giving and receiv-
ing labor-notes in transactions with his customers.
He propounded his theories in a work entitled the
" True Civilization," and some of his views elicited
the commendation of John Stuart Mill.
