CONTRIBUTIONS TO THE PATHOLOGY AND 
vessel, and adding a few drops of nitric acid, the semi-opaque urine 
at once became clear upon its upper surface, while towards the 
bottom of the test-tube the liquid was of a dull brown-green kind 
of colour : a slight effervescence also took place, which appeared 
to give rise to a number of very minute silvery-looking specks, 
which specks adhered to the sides of the tube : in a short time 
these specks conglomerated into globules ; and in the course of a 
few hours these globules subsided to the bottom of the vessel en 
mass. The morning following, this substance, which had fallen to 
the bottom, was floating on the top of the liquor, and it closely re- 
sembled recently made wood-ashes; minute flaky deposits were 
also at the bottom of the tube, which flaky masses I judged to be 
albumen. When the horse was first seized with abdominal pain, 
medicine was given to relieve it ; but whether it gave any relief, 
or prevented the beast from getting worse, I am not prepared 
to say. 
2 d. — To-day the pulse has continued pretty regular, beating at 
66 per minute. The breathing is attended with a loud harsh 
grating noise, which noise appears to come from the top of the 
trachea, or from the larynx. A discharge of bloody serum issues 
again from the left nostril. About eleven o’clock in the forenoon 
the left eyelid began to swell, and in less than an hour the swell- 
ing was larger than my closed hand. The right eye looks dull : 
bloody serum is discharged drop by drop from the inner canthus of 
both eyes. The mucous membrane of the eyes is covered with a 
bloody exudation. The sheath has also begun to swell very ra- 
pidly, and by four o’clock in the afternoon it resembled an immense 
bag. All abdominal pain ceased about ten o’clock last evening : 
he has dunged, and the faecal matter is covered with a coating of 
blood. He refuses all kinds of food, but has drunk freely of chilled 
water ; does not appear to have urinated for a considerable time. 
From this time I abstained from giving any more medicine ; I 
deemed it altogether useless. 
3c?. — The pulse has varied to-day from 76 to 84; the harsh 
tracheal sound which existed yesterday is entirely gone. I can 
detect an interruption to the respiratory murmur when I place my 
ear immediately behind the superior part of the left scapula : here 
the sound suddenly ceases, and in a moment afterwards is heard 
again. The murmur throughout the right side of the chest is per- 
fectly clear. Large swellings have manifested themselves upon 
both shoulders and down the course of the scapula, while the 
swelling over the left eye has disappeared, and the eyes are free 
from any serous effusion ; the dung is also free from blood. No 
appetite; altogether he appears considerably emaciated. In the 
evening, about nine o’clock, I first detected a peculiar change in
