REPORTS OF CASES.

notified that three or four others were sick. On arrival we 
found a grade heifer dead. She had been taken sick last evening 
and died before morning. Her stall was the next one to our 
patient of yesterday, which was in much the same condition as 
when we first saw her. 
There were three others more or less ailing, presenting symp¬ 
toms similar to the Jersey cow, with occasional switching of the 
tail, stamping of hind feet and lying down and getting up ; or y 
in other words, showing colicy pains, with hurried respiration, 
blueish color of the gums and a peculiar smell to the breath. 
We now became alarmed, thinking we had something of a very 
serious nature to deal with, and requested that another veteri¬ 
narian be called in council. 
We began an investigation of surroundings, etc., and soon 
discovered a cause. About a week or more before our visit the 
owner had thought to save himself some considerable work, and 
so had built a water trough, about four inches deep, and one foot 
wide, which passed through the mangers of the whole string of 
cattle, so that they could be watered without leaving their stalls. 
This trough had been made of unplaned green plank, not 
matched, but simply spiked together, and was probably seventy- 
five feet or more in length. Very naturally it leaked, and in 
order to stop this, he had used five pounds of white lead in coat¬ 
ing the inside at the joints and bottom. You can imagine how 
much would adhere to the saw marks of unplaned lumber. He 
had then watered the cattle from the trough every day, even to 
the same day he painted it. 
We now diagnosed lead poisoning, discontinued the use of 
the trough, and prescribed magnesia sulphate, sulphuric acid and 
iodide of potassium. On examining the herd we found eleva¬ 
tion of temperature, 102 to 104, in every one except one. So we 
treated the whole herd. One died the first night, one in three 
days, one in six days and one was killed. 
Dr. Gribble, of Elyria, saw the cattle with me. 
SORE MOUTH IN CATTLE. 
By H. Fulstow, V. S., Norwalk, Ohio. 
During the month of October I was called to see a cow for a 
Mr. Smith that would not eat. Upon my arrival I found a nice 
big cow, stiff all over, looking as gaunt as a greyhound, nose 
poked out and smacking her lips, with abundant saliva drib¬ 
bling from the mouth. Pulse slightly increased, temperature 
104°, mammary glands hot and upon trying to milk her strings
