[27] This, and the following experiments, are among those recorded by
M. Gaspard, referred to in the foregoing dissertation.
Two drachms of pus, somewhat fetid, derived from a large common ulcer,
and diluted with a little water, were injected into the jugular vein of
a middling-sized dog. The animal immediately made several convulsive
efforts to swallow, and soon became faint. It showed indications of
pain, and vomited more than six times in the course of the day. At the
expiration of an hour, it appeared slightly relieved by an evacuation,
and by passing turbid urine. In the evening, it was very ill; it lay
upon its side with its legs extended; had a very feeble pulse and
scarcely perceptible respiration. Ten hours after the experiment, it
passed black, liquid, and extremely offensive motions; these were
accompanied by immediate relief. The animal regained its appetite, eat
and drank freely, and went to sleep. The day following, it appeared
nearly well. On the third day, three drachms of the same pus were
injected into the opposite vein; after the lapse of a certain time,
there occurred, as in the first instance, faintness, vomiting, and
frequent desire to pass urine; twelve hours after the injection,
frequent liquid, white, and very fetid motions were passed, and the
animal died at the expiration of twenty-four hours. On opening the
body, no alteration was found either in the intestines or other organs.
