Simultaneous Epizootic and Epidemic Attacks. — 
Patte has spoken of diphtheritis occurring in man, in various 
degrees of intensity, in the spring of 1855, and at the same 
time several veterinary surgeons had occasion to observe the 
same form of angina in the horse. It would appear, how- 
ever, from the brief description of the cases occurring in the 
latter animal, that they partook of the nature of strangles, 
inasmuch as abscesses formed in the intermaxillary space and 
parotid region. Reynal observed, at the same time, several 
instances of croup in fowls. 
Croup in Calves. — Knielrisch observed a case of 
croup in a steer nine months old. As there was imminent 
danger of suffocation, tracheotomy was performed, and a 
mass of purulent mucus, tolerably firm, about the 
thickness of a finger, and five inches long, passed out, and 
had the appearance of having filled a bronchial ramification. 
As soon as this croupose exudation had been expelled, all 
sort of asphyxia disappeared, and the animal was instan- 
taneously restored to health. 
As a singular occurrence, Gros- Claude relates a case of 
angina membranacea (pseudo-membranous croup), in a nine- 
year-old ox ; the disease has hitherto only been described as 
occurring in young animals. The false membranes in ques- 
tion occur in the intestines as well as in the air-passages. 
Sticker has seen cylindrical masses of semi-organized lymph, 
measuring from ten to fourteen feet in length ; and another 
German veterinary surgeon, Prehr, has seen portions, from 
three to four feet in length, pass out with the dung. 
On a recent visit in Aberdeenshire, I was several times 
consulted about laryngitis in calves, which not uncommonly 
ends in death, and the mucous membrane of the air-passage 
is then found covered with semi-organized lymph. I saw two 
of these cases, like croup of infants, and the dyspnoea was 
very marked. The act of breathing was audible at a long 
xxix. 90
