NEPHRITIS AND PARAPLEGIA. 
presides over respiration and the spasmodic movements of the 
limbs. The action of pawing the ground with the hind feet , the 
nervous agitation of the muscles of the olecranon, indicated also 
that a portion of the same system that presides over the voluntary 
muscles was equally involved. It was by means of the perma- 
nence and augmenting intensity of all these symptoms that ex- 
haustion and death supervened at eight o’clock at night, twenty- 
four hours after the commencement of the attack. 
Autopsy . — Very intense sanguineous congestion throughout 
the whole extent of the mesentery. The mucous membranes of 
one part of the floating portion of the colon of a cherry colour. 
The ureters, the bladder, and the urethra, untouched. The 
kidneys blackened in many places through their whole extent. 
The cortical portion softened very deeply. The substance of 
the right kidney more disorganized than that of the left. The 
carcass distended with gas. A very great tendency to putrefac- 
tion. The blood black, oily, and thick. Much pulmonary con- 
gestion, sufficiently explained by the great difficulty and fre- 
quency of respiration. 
Case III. 
March 3d . — A mare, sixteen years old, of admirable form, of 
great power, of a nervo-sanguineous temperament, and in the 
highest state of fatness, had been ridden at the usual pace by 
her master, and, her work being over, had eaten and drunk as 
usual. She lay down at night, rolled herself several times, 
looked at her flanks, as it was afterwards recollected, and rested 
tranquil until the morning. At six o’clock she refused both food 
and drink — was dispirited, but still, and could scarcely be made 
to execute any movement. Her exterior temperature was as 
usual — the mucous membranes of a good colour — the pulse hard 
and slow — the artery rolling under the finger — the respiration 
short and frequent. 
Diagnosis. — This, which, according to custom, I was com- 
pelled to give, was “ a gastro-intestinal affection, with the com- 
mencement of sanguineous congestion of the mucous digestive 
surface.” 
Symptoms. — The alvine dejections were frequent, slightly 
formed, and containing some imperfectly digested food. There 
was no appearance of suffering ; she carried her head well, and 
sought for something to eat. The movements of the flanks were 
always somewhat agitated and short, and the alae of the nose 
were distended. 
She was bled to six pounds — the blood was black and 
plastic, and the colouring matter predominating. Two hours
