PLEURO-PNEUMONIA IN LAMBS. 
By J. D. Peech, M.R.C.V.S., Wentworth. 
At the request of Mr. Mann, of Scawsby Hall, I recently 
made a post-mortem examination of a lamb which had died a 
day or two previous to my receiving it, from a disease which 
has all the appearance of an epizootic ; indeed, there can be 
little doubt of the fact, as between 40 and 50 of the lambs 
in the same flock have died in a very short time. 
The symptoms that were related to me by Mr. Mann are 
as follows : — A blue appearance about the nose, lips, and 
mouth, tongue studded with small spots of a red colour, 
mouth hot, breathing very much accelerated, quick and short 
in character , a great disposition for quietness and separation 
from the other sheep, and, if suddenly disturbed or moved, a 
painful cough would immediately come on, which was, 
however, more severe in some cases than others. Sometimes 
a pair of lambs, twins, would be affected, in other cases only 
one of a pair. The bow r els are generally constipated. 
The lamb submitted to examination, illustrated the disease 
in an advanced stage, it having been ill from five to six weeks. 
After removing the skin, the muscular tissue w 7 as observed to 
be very much wasted and pale in colour. 
On opening the abdomen, the stomach and intestines were 
found to be healthy, and to contain a fair quantity of ingesta. 
The liver was congested, but the kidneys were free from 
disease. 
On laying open the thorax the right lung was found to be 
one complete mass of disease. And on removing the sternum, a 
large abscess, situated in the antero-inferior mediastinum, was 
brought into view, which had evidently been existing for 
some time, as the contents were thick and grumous, and might 
be easily removed in masses with the scalpel. 
The lung itself, the right one, was completely hepatized, 
and about the centre of its costal surface a portion of the 
organ, of an irregular shape, was of a very dark colour: 
at this part softening had commenced. The tissues were fast
