ANTIMON IAL POISONING.

was placed under the influence of hydrogen gas, which is a 
narcotic of a low power — perhaps, indeed, only a negative 
narcotic, like nitrogen. The presence of the hydrogen could 
not, however, have had much influence, as nothing like deep 
sleep or insensibility was observed during the time of the 
experiment. 
Experiment III . — Introduction of Tartar Emetic by a 
Wound . — At my request, Dr. Barker of Bedford, performed 
the following experiment: From the back of the neck of a 
full-sized dog, the hair was removed for a space of the size of 
the palm of the hand ; a crucial incision was made in the 
part, and the wounded surface was dressed with tartar 
emetic ointment, made by mixing up an ounce and a half of 
the salt with four ounces of lard. The wound was dressed 
with this ointment every morning for seven days. The appli- 
cation gave rise to but little local mischief, except that the 
temperature w r as slightly raised, and that a slight oozing of 
matter took place from a point removed a slight distance from 
the wound. From the time of the first dressing, the animal 
lost appetite, but throughout was neither purged nor vomited. 
He refused food, became gradually thin and exhausted, and 
died as from inanition, without any other remarkable symp- 
toms. 
The dog was sent to me directly after death : I examined 
him seventy-two hours after the fatal result. The cadaveric 
rigidity was well marked. In this, as in the preceding cases, 
intense congestion of the internal organs was the most striking 
general appearance of a pathological kind. The blood was 
fluid, and such few clots as were met with were loose and 
dark in colour. The heart was filled with blood on both sides: 
the aorta was full of blood. The luugs were inflated, of a 
pink colour, and much less free from congestion than the 
other organs. There was no indication whatever of pulmonary 
inflammation. The bronchial membrane was healthy. The 
liver was congested ; the spleen natural. The stomach con- 
tained ten drachms of a very dark, thick, bloody looking 
mucus. The inner surface of the stomach had the same red 
appearance seen in the before-named cases, mapped out much 
in the same manner, and situated in the same locality. There 
was no ulceration. The intestines held no solid matter, but 
were thinly coated with a bloody mucus, like that in the 
stomach. The whole of the intestinal canal was injected, and 
the colon and rectum presented bloody spots as from a rup- 
ture of the minute vessels, but there was no actual ulcerated 
spot. The kidneys were of a purple colour from congestion. 
The bladder was full of urine.
