J> TENIA MEDIOCANELLATA IN A COW. 
By A. Peters, Student . 
In July last this cow, a three-year-old Jersey, owned by E. H. 
Austin of Gaylordsville, Conn., was noticed to be unwell. This 
was not unexpected, as her grandmother had died five or six 
years before, and her mother two years before, with very nearly 
the same symptoms. An aunt of this cow, by a native bull, had 
also died with similar symptoms. 
Symptoms .—Emaciation and weakness; shrinking of and a 
final cessation of the milk secretion ; swelling in the sub-maxil¬ 
lary region, which would vary in size, being larger at some times 
than at others. Later on in the disease, there was a persistent 
diarrhoea, the foeces being very liquid, and not yielding to simple 
treatment, such as dry food, gruels, etc. 
Post mortem examinations were made on the grandmother 
and mother by a butcher, who said he failed to discover any ab¬ 
normal condition of the lungs or intestines. Still, from the his¬ 
tory of the case and the symptoms, a probable diagnosis of 
tuberculosis was made. On the 7th of November, 1882, the cow 
was destroyed, and a postmortem examination made. No tuber¬ 
cular deposits could be found, either in the lungs, which were 
perfectly healthy, or in the intestines or mesentery. The sub¬ 
maxillary lymphatics were somewhat enlarged and hardened, but 
in other respects were normal. The whole intestinal tract was, 
however, very much inflamed and congested, particularly the 
small intestines. There was a large secretion of a muco-purulent 
matter in both the large and small intestines, and the small intes¬ 
tines were very much softened, tearing very easily ; the mucous 
membrane could easily be scraped off with the thumb nail. In 
the small intestines were two large tapeworms, each about six 
feet in length. They were more like those found in the human 
family than any that have ever been described as infesting 
bovines.
