ETHIDENE DICHLORIDE.--ETHIYL BROMIDE. 87
not be confounded with eserine or phtysostzgm;zinc, which
also occurs in the same plant. Eseridine has the formula
C15H,23NO3'
Physical Properties.-The melting-point of eseridine
is 269.6 F. (1320 C.), thus differing from its sister alka-
loid, eserine, which melts at 194 F. (9o C.).
Solubility.-The alkaloid escridine dissolves in ether
with difficulty.
Therapeutic Applications.-This drug has been
recommended so far only in veterinary therapeutics as a
purgative for herbivorous animals.
ETHIDENE DICHLORIDE.
This drug is also termed monocklorethyl chloride, with
a formula of C2H4C12.
Therapeutic Applications.-This drug is now used
occasionally as an anaesthetic, but it has not been thor-
oughly studied.
ETHYL BROMIDE.
Bromide of ethyl, which is also known under various
other names, such as cethrbromatus, brom-cthyl, lhydro-
bromic ether, and monobromthanle, has the formula
CHBr.
Physical Properties.-Ethyl bromide is a colorless in-
flammable liquid with a burning taste and a sweet odor
resembling that of chloroform. When pure it boils at
from 0oo.4 to Io2.2 F. (380 to 390 C.), and its sp. gr.
at 590 F. (15 C.) varies from 1.419 to 1.420.
Solubility.-Bromide of ethyl is readily soluble in
alcohol, ether, and chloroform, but is insoluble in water.
Physiological Action.-The dominant action of this
drug is that of a general anaesthetic.
Circulation. -The blood- pressure is not affected by
small doses; it is lowered and then elevated by larger
amounts, owing to changes in the respiration; it is finally
diminished from paralysis of vaso-motor and cardiac
origin. The pulse is at first accelerated, due to stimula-
