DOREMUS
entrusted with nearly all the important medico-
legal cases in New York and vicinity as a chemi-
cal expert, and for this woi'k he established a
special toxicological laboratory, kept under lock
and key and sealed. He was the expert in the Bur-
dell murder case (1857), and the Mrs. Stephens
murder case in 1858, and his skill disi^layed
in these cases gave him a wide reputation. He
was also for twenty -five years the principal expert
in patent suits involving a knowledge of chem-
istry, electricity and kindred branches of physics.
With his assistant. Dr. D. L. Budd, he devised in
1861 a method for using granulated gunpowder
in cannon without the serge envelope. By com-
pressing the grained powder in a solid elongated
mass he did away with the necessity of sponging
the gun after each discharge and at the same
time relieved the strain upon the gun. Napoleon
III. witnessed its demonstration at Bois de Vin-
cennes and the French government adopted the
system. "La<Poudre Comprimee " was also used
in Mt. Cenis tunnel for blasting. In 1863 he ac-
cepted the chair of chemistry and physics in the
Free academy, afterward knovv-n as the College
of the city of New York. He there established a
chemical analytical laboratory and also the first
physical laboratory in New York. He introdviced
in 1865 the use of chlorine gas as a disinfectant
on cholera infected ships and in hospitals and
asylums, thoroughly disinfecting the entire
buildings and even the stones used in their con-
struction. The same year the death of his little
boy by his dress taking fire, led him to investi-
gate and determine some chemical that, applied
to light fabrics, would render them fireproof. He
found it in a solution of phospliate of ammonia,
which was used effectively in theatres and else-
where. In 1871 he was appointed president of a
board for examining druggists and prescription
clerks. He introduced reforms in manufacturing
and purifying illuminating gas, and in methods
used in testing the purity of milk. He patented
methods for quickly extiuguisliing fires on ship-
board with liquefied carbonic acid and discovered
a method of bleaching gray ostrich feathers with
the peroxide of hydrogen and ammonia, which
resulted in the commercial use of the peroxide as
a disinfectant. He received the degree of LL.D.
from the University of the city of New York in
1874. He was elected a fellow of the New York
academy of science and of the New York geo-
graphical society, and a member of the New York
electrical society, the Union league club and
the St. Nicholas society . He was president of the
Medico-legal society, editor of the Journal of the
New York medical college, established 1852; and
of the chemical definitions in the " Standard
Dictionary " (1891-94), his associates in the work
being Dr. Marcus Benjamin and ^I. A. Eourgoug-
non. He lectured in 1854 before the New York
Mechanics' society on "Electricity" and ar-
ranged a row of arc lights around the gallerj^ of
the hall. The previous year he had lectured on
" Light " and caused daguerreotypes to be taken
of the occupants of the proscenium boxes by aid
of the electric light. In the course of three lec-
tures for the benefit of the Brooklyn mercantile
laboratory, 1865, he first exhibited the chloro-
hydrogen jet, Stewart's electro-motor and other
electrical devices. In 1873 he lectured on " His-
tory and Properties of Anaesthetic Agents" for
the benefit of the widow of Dr. Horace Wells,
who first used " laughing gas " for dental opera-
tions in 1844. In 1876 and 1877 he lectured before
10,000 persons at Chautauqua on "Physical
Science " and in 1892 on the " Agreement between
the Mosaic and Scientific Histories of the Crea-
tion," involving astronomy, chemistry, geology
and physics, and illustrated by colossal apparatus
weighing several tons. His bibliography includes:
Impurities in Soda Water; Analyses of Solidified
Milk; Disinfection of Cholera Ships; Disinfection of
Bellevue Hospital; The Lactometre; The Improjyer
U^e of Cocaine; Duties of Experts and Others in
Poison Cases (1880); Timj Death Dealers (1884);
The Comparison of Medical Education at Home and
Abroad; The Harmony Betioeen the Scientific History
of Creation and the Mosaic Becord: The Impurities
of Croton Water; Preservation of the Egyptian Obe-
lisk; The Microscopie; Toxicology; Medical Juris-
prtidence; Transactions of the First Pan-American
Medical Congress (1893).
