tube is closed with a cork, to prevent the entrance of the exter¬ 
nal air; and five or six hours afterwards, providing no fresh 
gas is disengaged on the removal of the cork, the canula may 
be withdrawn. This precaution is useful in mephitic indiges¬ 
tions complicated with distention of the paunch; in which it is 
occasionally necessary to leave the canula in for several days, 
in consequence of a renewal of the fermentation. The wound 
should be covered over with a plaster of pitch mixed with com¬ 
mon turpentine. 
M. Chretien has constructed a similar instrument of less di¬ 
mensions for practice on sheep and g-oats; although, as he 
justly remarks, to these animals the professional man is rarely 
called : still, such an instrument might prove highly useful in 
the hands of farmers and graziers ; and those individuals who 
have large herds and flocks do not consult their own interest 
when they neglect to provide themselves with means so simple 
and cheap, which in the season of their being required, may 
turn out to be an invaluable life-preserver to their live stock in 
general.

Post-mortem Appearances, 
THE tongue usually swelled, discoloured on the dorsum, vary¬ 
ing from a dark red to a dingy purple, more red mingling to¬ 
wards the point and edges. The large papillse near the root 
of the tongue prominent. The sublingual glands generally 
enlarged, with appearances of inflammation; and the lesser 
glands under the membrane of the mouth likewise tumefied. 
I suspect that an occasional enlargement of these has been 
mistaken for pustules. No particular redness or engorgement 
of, or about the fraenulum linguae, whether the dog has or has 
not been wormed. All the glands concerned in the secretion 
of saliva increased in size and vascularity. Some inflammatory 
appearance extending over the arch of the palate, and the 
whole of the fauces. The tonsils enlarged, and sometimes 
considerably inflamed. I do not recollect a single case in which 
the tonsils have not been affected, and to this affection of the
