pulse is scarcely marked, it must be treated in the same manner 
as hydrothorax. 
Pleuro-pneumonia .—Inflammation of the lungs is often accom¬ 
panied, particularly in the horse, with inflammation of the pleurae. 
The disease then announces itself by the symptoms common and 
particular to both maladies. It is in these cases much more 
serious than when one only of these affections exist. Bleedings 
ought to be followed up by local ones, and which are particularly 
successful in the treatment of pleurisy. The other therapeutic 
treatment remains the same. 
The Pernicious Effects of Mercury on Ruminants, 
AND PARTICULARLY ON THE Ox. 
By M. Barraud, T.N., Barherieux. 
On the 15th of April, 1814, I was called in to look at an ox, 
which had on one of its legs a tumour of a scirrhous nature, and 
so situated as to be easily seen. It had made so much progress in 
a short time, that the owner began to fear lest the animal would 
be permanently blemished on that part, and thus lose a great part

I ordered the first rubbing to take place on the same day, and 
advised that it should be repeated daily for four days ; thinking 
that by that time all the ointment would be used, and the imme¬ 
diate effect which I expected, produced. 
On the 19th they informed me that since the preceding 
evening the animal had refused to eat, and appeared to be very 
ill. I was not able to see it until the 20th, when I found it in a 
pitiable state : it was sadly depressed; the horns, the ears, and 
the whole surface of the body were cold; the muzzle was dry, 
the eyes weeping, the pulse small, weak, and hurried ; there 
existed a serous diarrhoea; the evacuations,which were very abun¬ 
dant, diffused around a cadaverous and extremely foetid odour; 
the animal obstinately refused either to eat or drink, and I 
regarded it as lost. Nevertheless, I wished to try some means. 
I administered mucilaginous drinks, rendered anti-putrescent and
