culons in nature. Sometimes it exists along with pulmonary 
and pleuritic lesions, at others it is primitive and exclusive. 
During the yq^r 1900, out of 32 cases of tuberculosis, the author 
has found 15 cases of pericarditis, and taking these figures into 
consideration, he has found the following records, viz : 6 cases 
of serous tuberculous pericarditis, 6 cases of hczmorrhctgic , 3 of 
symphysar , o of suppurative. These varieties are differentia¬ 
ted at post-mortem by the following lesions : The serous by 
the presence of tubercles spread on both layers of the pericard¬ 
ium and sometimes in irregular masses, sarcomatous in aspect, 
situated principally at the base of the heart. The cavity of the 
pericardium contains fluid in small quantity, similar to the 
normal exudation. The hczmorrhagic has fluid looking more like 
blood in nature. As much as three litres has often been found. 
After emptying the cavity, the serous membrane is found cov¬ 
ered with anastomotic vegetations spreading over the surface 
of the heart. The lesions are of sub-acute nature. In the sym¬ 
physar pericarditis the characters of chronicity are found. 
Cardiac symphysis is incomplete when there is adhesions, fibrous 
bands, dividing the cavity into sections ; or, again, it is com¬ 
plete when the pericardial cavity has entirely disappeared by 
adhesions of the two layers. The heart is then enveloped with 
a thick fibrous covering, made of the two layers of the serous 
membrane thickly adherent to each other.— (Rec. de Med. Vet.) 
Irreducible Hernia in a Slut [. Ducomon ]. — A fine 
five-year-old fox terrier slut has an elastic tumor on the right 
inguinal region. Although it is irreducible, it is evidently a 
hernia which demands surgical interference. With all anti¬ 
septic precautions and care the animal was operated. An in¬ 
cision made from forwards backwards and a little from outwards 
inwards exposed the hernial sac, which, on account of the irre- 
ducibility of the hernia, was incised. The right horn of the 
uterus and a portion of the omentum are in the sac. The 
omentum is removed by resection after ligature. At that 
time a loop of intestines is found between the uterus and the 
abdominal opening. The intestines are pushed back, but still 
the hernia of the uterus cannot be reduced. Hysterectomy is 
resorted to. The wounds were sewed with antiseptic sutures, 
covered with iodoform and a dressing of iodoformed collodion. 
In fifteen days the cicatrix was complete.— (Rec. de Med. Vet.) 
Tetanus Supposed Consecutive to the Absorption 
of Toxines through Intestinal Lesions [M Remond ].— 
The etiology of this case is only problematic. A. gelding, aged
