ART. XXXIII. — EXPERIMENTS WITH THE WOURALI POI- 
SON. Performed by Mr. Waterton, at the Medical School, Not- 
tingham. 
Extracted from a Letter of W. R. Clanny, to the Editor of the Lancet, 
For the first experiment a large dog was chosen. To 
prove the certainty of the action of the poison to destroy life, 
an incision was made in the side of the dog, and a spear-head, 
covered with the poison, inserted into the wound; this was 
left in the side, in order that the poison might be absorbed 
into the system. In about a quarter of an hour the circulatory 
system was much increased, the pulse rising to 130 in the 
minute, and the action of the heart being irregular; the crea- 
ture was unable to stand at 36 minutes after the insertion of 
the poison; convulsive twitchings of the whole body were 
evident, and the pulse continued irregular up to the time of 
its death; at 52 minutes it ceased to breathe, but the heart con- 
tinued its action; in a few minutes after the chest was opened, 
and the heart irritated with the end of a scalpel, but in ajshort 
time the irritability ceased. 
The second experiment was then entered upon, and an ass 
was chosen for it. It was intended, in this experiment, to use 
artificial respiration during the whole of the time that the 
animal continued under the influence of the poison, so that 
when its power had ceased, the creature would resume its 
natural respiration, and the artificial means be discontinued, 
thus enabling it to survive the powerful effect of this most 
deadly poison. The arrow-head, covered with the poison?
