Biliary Obstruction Caused by a Parasite [A. Mar- 
stoii\ .—The author was requested to examine a pig which was 
suspected of swine fever, but failing to discover any indication 
of the disease, the animal was slaughtered. At the post-mortein 
which was made all the internal organs were found healthy ex¬ 
cept the liver. The gall-bladder was found of very large size, 
about three times larger than normal, and was filled with fluid; 
on the inside was found a worm, three inches in length, about 
the size of a lead pencil. It completely closed the biliary duct 
_( Vet. Record.') [This worm belonged probably to the ascaris 
megalocephala.—(A. L.)] 
Lactation in a P a oal [A'. P. Smith). — Cases of early lac¬ 
tation in young females are not rare, but the one reported by 
the author is more surprising than any on record. It is that of 
a foal, one day old, which had congestion of its mammary 
o-lands. These were well rubbed and soon milk began to flow 
freely—a pint of it was obtained the first time. The animal 
was milked for several days in succession and after ten or twelve 
days dried. The foal remained all the time in good health, but 
on the ninth day she was strongly in season, as her dam herself 
was.—( Vet. Record.) 
Foreign Body in the Stomach of a Dog [A. S. Hodg¬ 
kins ].—Foreign substances often occasion trouble in dogs, and 
their nature varies considerably. The following case is, how¬ 
ever, unusual : A five-year-old Yorkshire terrior became sick. 
The nose was moist ; eyes bright; he was lively, but emaciated 
he had a constant irritating cough. Placed under tonic treat 
ment, good food and so forth, he went on for a few days, when 
one morning he began to scream as in great pain. Having 
some constipation he was given two aperient pills and placec 
in a clean kennel, where he remained looking very sickly 
drowsy and screaming now and then. Four hours after he hac 
taken the pills he was taken with vomiting, and on examinatior 
of the thrown-up mass it was found containing a piece of leac 
pipe, in. thick, 2 inches long and weighing i y 2 ounce. Th< 
screaming stopped suddenly, the dog took a drink of warn 
milk, the bowels acted” freely and the next day was sent hotn< 
cured. It seems that there had been plumbers about the hous*
