RECORD OF A CASE OF TETANUS. 
diately afterwards half a drachm of prussic acid was adminis¬ 
tered by injection into the rectum. She was then left again 
for the night, but in the course of an hour she was dead. 
Duration of illness about thirty-six hours. 
She had not received (as far as could be ascertained) any 
wound or injury, but there was a small abscess on the back, 
which had existed several days, and had suppurated. She 
had been exposed, in her every-day work in the field, tc the 
extreme inclemency of the weather—cold, pelting showers of 
hail, sleet, or rain, but was, in all respects, similarly treated 
to the other horses, and had a comfortable stall stable. Her 
food consisted of good clover hay, some mangold wurzel (of 
which the horses are very fond), and some oats and bran. 
There was nothing unusual in her general treatment to 
account for the illness. 
Throughout the illness, the tail was somewhat firmly 
erected towards the left side. The jaws, also, were firmly 
clenched. The breathing became gradually more hurried , 
diffictdt, and sonorous , and the agony seemed to be great. 
The muscles of the neck were very rigid and hard, and 
the muscles of the abdomen developed themselves very much 
in the efforts of breathing. The mare in turning round 
did not bend any part of her, and the straw on which she 
stood became twisted into a sort of rope about her legs. 
Post-mortem examination. —The day after death, that is to 
say, about thirty-six hours, she was opened. First, the jaws 
and throat were examined, and a slight scratch or two were 
seen on the tongue and near the grinders on the side of the 
mouth, from which a little blood had been seen during life 
to fall. The trachea, fauces, and larynx were stained with 
dark blood. The heart w r as similar, but it did not contain 
any coagulum, only some dirty-looking blood-like fluid. The 
pericardium was rather full of serum. The lungs were 
healthy, but on one side were rather gorged with blood, as if 
from gravitation after death; and so with the other organs, 
which all appeared free from inflammation. The liver was 
rather soft , and of a dirty-eartliy colour, approaching black¬ 
ness, on the depending side. The kidneys seemed healthy, 
and likewise the stomach and bowels. The stomach con¬ 
tained no solid matter, but a few pints of fluid stained of a 
yellowish colour. The contents of the colon were similar. 
The small intestines contained a small quantity of digested 
matter. The mare was fat. No fluid was found in the 
head, and the cerebrum and cerebellum seemed healthy, 
the blood-vessels not being at all gorged. The spine was 
not examined. A few patches about the intestines were
