POSTSCRIPT. 
Since reporting the above joint cases I have to add another 
application of Schmidt’s treatment:— 
Case V (^Recovery followed by Mastitis ).—On October 5, 
early in the morning, I was called to a cow at Bayside that had 
calved three days previously and had shown first symptoms of dis¬ 
ease the night before I received the message., 1 found the cow, a 
fine Jersey, in a box stall in a lying position. She was utterly 
unattentive and at times would groan. The head was still held 
in a straight position, but the neck showed a peculiar stiffness. 
The owner, a farmer, had already made the diagnosis of milk 
fever and gave up the cow as lost, reiterating that her mother 
also had died of milk fever. I did not have the infusion appara¬

copious bedding, removing a large quantity of dry faeces from 
her rectum and applying a clyster of glycerine and water. As 
I was out of caffein I gave a hypodermic injection of eserine, 
and then drove to my office, which is about two miles distant. 
Returning in the afternoon, at 2 o’clock, I found the cow worse 
and applied quickly the infusion of iodide of potassium—about 
18 to 20 hours after first symptoms of disease. I gave also a sec¬ 
ond injection of eserine, as the peristalsis was totally suppressed, 
warned against any other treatment and left, fearing that the in¬ 
fusion had been applied too late. When I called the next 
morning I found the cow standing in her stall, somewhat ema¬

appeared normal, but milk secretion was scanty. 
On October 9, four days after the infusion of the medicine, 
I was called to the same cow and found her suffering from a 
left-sided mastitis. The owner naturally brought this complica¬ 
tion in direct connection with the infusion. But inasmuch as 
the cow had apparently recovered from milk fever, but had been 
confined during five days in a warm box-stall and then turned
