it ; coat hard and dry; rumination had ceased; frequent cough, 
with much pain; looked exceedingly dull ; mucous membrane 
injected. She was standing alone in the field. 
Diagnosis. — Pleuro-pneumonia. 
TREATMENT. — 1 gave mag. sulph. et pulv. zingib. : half pound 
of the former and half an ounce of the latter; this to be repeated 
in twelve hours.

2 d . — Symptoms a little abated. Pulse 72 ; respiration 32. 
3d. — Improving. Pulse 70 ; respiration 28, and quieter. 
Give sol. cup. ammon. et pul. zingib. et gentianae, as in my 
former cases.

The case was persevered with for a week longer, and did 
well. The above cases, imperfect as they may be, go to shew 
that venisection is not called for in every individual case ; and I 
am convinced that if bleeding be not had recourse to almost as 
soon as the animal is attacked , it will be better to leave it 
alone. It is a singular fact, that, notwithstanding there are thou- 
sands of cattle in this country, it is quite a rare thing to hear of 
a practitioner being called to attend one when diseased. The 
custom of this country is to procure a “ charm” If the people 
here would take a hint from the English agriculturists, it would 
be the means of lessening some of their distresses, while it 
would most assuredly put a large sum of money annually into 
the pockets of cow-keepers. This year I have found “ mam- 
mitis” very prevalent amongst stock, in consequence of the 
“ custom.” I meet the cases when they become “ chronic” and 
necessarily troublesome. 
Should these observations be worth recording, they are at 
your disposal. 
N.B. — I had no opportunity of making any post mortem 
examination of either of the cows.
