PLEUROPNEUMONIA IN SHEEP. 
They generally die from the third to the sixth day after 
they are first attacked. 
Post-mortem appearances .—The last sheep that we opened 
belonged to Mr. Lowndes, Shaw’s Farm, Tissington, which 
may be taken as a type of all the others. The abdominal 
viscera were healthy. The lungs were evidently the seat of 
the malady, and in this case it was nearly confined to the left 
side. The pleurae costalis and pulmonalis were much 
diseased, and adhered to each other. The lung was very 
much enlarged, and had become consolidated, being as hard 
as liver, and when cut into, it had a marbled or variegated 
appearance, resembling the lungs of a cow which had died 
of pleuro-pneumonia. We have never found much serum in 
the chest, although the pleurae generally were adherent, but 
I have heard of a few cases in which it existed. 
I know some farmers who have lost a fifth part of their 
sheep from this disease. 
I am fully satisfied in my own mind that pleuro-pneumonia 
among cattle is infectious, and have been ever since my paper 
on this subject appeared in the September number of the 
Veterinarian for 1842; since which period I have had ample 
opportunities of ascertaining whether or not the disease could 
be or ever was communicated from the cow to the sheep; but 
although I have seen these animals depastured together, and 
even kept in the same building, the latter never became 
infected. 
Where this disease has appeared among sheep, I am not 
aware that cattle affected with pleuro-pneumonia have, in 
any one instance, been near them. Whether or not it is 
infectious among themselves, I am not prepared to say at 
present. 
The recoveries after treatment were about one fourth. 
One farmer told me that he succeeded best with a moderate 
bleeding at the onset, and afterwards giving castor oil with a 
little brandy, so as to act upon the bowels, constipation being 
always present. 
Taenia in lambs has also been very prevalent this year, 
producing diarrhoea and death. I find the remedy that I 
recommended in the Veterinarian for 1855, the most effective 
that can be resorted to for their eradication.
