UNIVERSITY FARM OUTBREAK. 271 
case entirely through itscourse from the onset until the fatal 
termination, the temperatures were normal or subnormal 
throughout. 
In the outbreak which occurred among cattle at the Uni- 
versity Experiment Farm the disturbances of the nervous 
System were particularly marked, so much so that the diag- 
nosis based on ante and post-mortem symptoms was unani- 
mously considered to be a cerebro spinal meningitis. 
Several of these cases at certain stages very closely re- 
sembled typical cases of parturient paresis. (See letter from 
Dr. Hela under ‘“‘Caffrey Outbreak.’’) It should perhaps be 
noted that we had one cow taken sick with all the clinical 
symptoms of this latter disease, the symptoms appearing 
about 36 hours after parturition. (See ‘A Supposed Milk 
Fever Case.’’) This case appeared on May 28th and the cow 
died on the 29th, the diagnosis being parturient paresis, 
The potassium iodide treatment was given quite early in the 
case. The first dose of 10 grams apparently hadno effect up- 
on the course of the disease, and a similar dose was given 
about six hours later; this also without any apparent effect 
upon the case. The outbreak previously described as ap- 
pearing among the dairy cattle belonging to the Univessity 
Experiment Farm appeared on June 8th, or about 11 days 
after this supposed milk fever case. No examination post- 
mortem was made of the latter but in view of the fact that 
several of the cases which appeared in the general outbreak 
among our cattle very closely resembled milk fever in all 
points except in the history of recent parturition, grave 
doubt has arisin in the mind of the writer whether the sap- 
posed milk fever case was not acerebro spinal type of hz- 
morrhagic septicaemia instead of parturient paresis. The 
writer can well understand that a suspicion as to the accu- 
racy of the diagnosis in an apparently typical case of partu- 
rient paresis may appear somewhat peculiar tosay the least, 
but to those of us who saw the cases among our University 
Farm cattle it does not seem peculiar at all. There does not 
appear any reason why this peculiar type of haemorrhagic 
septiceemia could not appear 36 hours after parturition as 
well as at any other period. If we consider the sudden 
checking of milk flow, the constipation, the posterior pa-
