and though feeding well showed weakness in his work. He 
has not been affected with colic before. This time he shows 
slight signs of intestinal pain, has a pulse of 60 and a normal 
temperature. Seventy minims of barium chloride are injected 
in the jugular vein, and within two minutes fell down dead. 
At the post-mortem there was found a slight congestion of the 
duodenum, with ascarides in its interior, and the heart had a 
longitudinal rupture of the right ventricle eight inches long. 
Prof. McFadyean, who examined the heart, said he found no 
diseased change about it. The author has never had any trou¬ 
ble with this treatment, giving sometimes as high as 80 min¬ 
ims of the drug.— {Vet. Record.')

Extirpation of Cord Abscesses in the Mastoido- 
Humeralis Muscre \By Prof. Lanzilotti-Buonsanti\. —This 
mode of treatment is gradually taking the place of the old 
method by drug cauterization, with the red iron, and the appli¬ 
cation of blister. The author, who has had several times occa¬ 
sion to resort to it, divides the operation into four steps : 
(i) Incision of the skin and subcutaneons tissue , in the direc¬ 
tion of the great diameter of the swelling and more or less par¬ 
allel to the jugular groove. Small dissection of the cutaneous 
edges on each side, to uncover the tumor. (2) Incision of the 
mastoido-humeralis , in the same direction as the cutaneous in¬ 
cision and extending to the cavity of the abscess. This inci¬ 
sion must be done carefully, by layers, and sometimes has to be 
cpiite deep. There is 110 danger in doing it, as only small 
blood vessels may be divided, which can be easily ligated or 
stopped with forceps. (3) Lateral dissection of the walls of 
the muscles, so as to isolate the superficial healthy structure 
from the deep, which is degenerated. This healthy part may 
be one centimeter thick or even less, but always sufficient to 
keep up the nutrition of the skin and prevent its ultimate 
sloughing. (4) Removal of the degenerated parts of the tu¬ 
mor. This is the most delicate part of the operation and the 
most dangerous. It is sometimes necessary to ligate the blood 
vessels, carotid and jugular, above and below the tumor, when 
this is taken hold of firmly, pulled outwards and removed by 
sections. The cavity, of various sizes, which is left is then well 
scraped, the ligatures, if any, are removed, a drainage tube put 
in place, and a suture applied on the skin and the remaining
