from above until the fluid was obtained from it; into this 
the tow was dipped, and the tow was then inserted deep into 
the muscle. All those cases where inoculation was performed 
in the forearm went on favorably, the wound suppurated, 
and cast off the tow and the excess of virus, and ended favor¬ 
ably. Those that were inoculated in the tail were weak in 
the lumbar region, and had to be assisted to rise; none that 
were inoculated in the forearm suffered in that way. In 
three of those cases that were inoculated in the tail the tail 
swelled, and the swelling extended up the tail to the buttock, 
and as far forward as the hip-joint; and the tail became stiff, 
and stood up horizontally. In two instances the rectum was 
closed up and the urethra stopped, and no urine or faeces 
passed. One of these I killed, and I have a piece of the 
lung here with me. I attribute the rising of the inoculation 
up the tail to the want of a healthy suppurating cyst, because 
inoculation proves this to be a disease of the aureolar tissue 
of the body; and it is a law with respect to this tissue, that 
suppuration never takes place in it unless there is great 
exposure to the air. Unless the air gets into the part, indu¬ 
ration follows; and the cells being stored with lymph and 
cellular fluid, these become indurated as hard as this table, 
and very thick T 
This method of inoculating cattle appears to be an awkward 
mode of inserting a rowel, which is often practised in this 
country on calves, from a belief that a rowel tends to prevent 
the disease sometimes termed quarter-ill. It is certainly 
surprising that it had not occurred to the operator, Mr. 
Pottie, that the insertion of a rowel in the dewlap would 
most probably prove equally effective, both as a preventive 
and a curative of pleuro-pneumonia, as the use of any matter 
obtained from the lungs of diseased animals .—North British

CARBOLIC ACID AND M‘DOUGALL’S DISINFECTANT 
PREPARATIONS. 
Carbolic or phenic acid is one of the most recent and 
useful additions to veterinary medicine; it closely resembles 
creasote in its properties and uses, and is one of the many 
interesting products of late years obtained from coal-tar. In 
an impure state, it is a black, oily, treacle-like liquid, with a 
disagreeable smoky taste and smell. When purified, it is an 
oily and nearly colourless fluid, neutral to test-paper, and of 
the specific gravity 1062. When deprived of its water, care-
