[*** We shall be at all times most happy to hear from 
Mr. Gudgin. — Ed. Vet.] 
EPIDEMIOLOGICAL SOCIETY. 
Dear Sir, — A short time since, I filled up a circular that 
I received from the Epidemiological Society, respecting the 
pleuro-pneumonia in cattle : the answer I sent to one of the 
queries, I wish to correct, through the medium of your 
Journal, as I quite forget the Secretary’s address. The 
question I refer to is, whether diarrhoea is a concomitant 
sym.ptom in pleuro-pneumonia , or words to that effect. I re- 
plied in the negative , in regard to my own observations ; 
since then two cases have occurred in my practice, and 
recently, which terminated fatally. The cows were in a shed 
when attacked, and had been fed on good sound hay, and 
slept perfectly clean ; an easterly wind prevailed some time 
before they sickened, one cow had calved six weeks previously, 
and had in addition to the usual symptoms painful distension 
of the rumen, immediately after eating a little hay. This I 
attributed to the great increase of the size of the lungs from 
engorgement of blood, pressing on the oesophagus, diminish- 
ing its calibre, and preventing the return of food to be re- 
masticated, hence the accumulation of gas, &c. in that viscus. 
The other, an old cow, was barren and dried preparatory for 
feeding, purged excessively , strained violently, voiding blood 
and mucus. However, before the grim tyrant closed her 
earthly career, their symptoms were abated by the adminis- 
tration of opiates : they both died in an exhausted state after 
about five weeks’ illness. 
Post-mortem Appearances . — Lungs enlarged, hepatized, and 
contained several small abscesses. / 
I trouble you with this communication thinking it may 
catch the eye of the Secretary to the laudable Society before 
alluded to, 
I am, dear Sir, 
Yours respectfully,
