EXTRACTS FROM EXCHANGES. 
724: 
In the angle included between the posterior border of the 
last rib, and the transverse process of the first lumbar verte¬ 
bras, an incision is made through the skin, 7 to 10 cms. long 
according to the size of the animal. 
The muscular layer is cut through, the peritoneum stripped 
away by the index finger, and the hand inserted between the 
peritoneum and the psoas muscles, without injuring the peri¬ 
toneum—an extraperitoneal operation. 
The kidneys are then grasped with the fingers, shelled out 
of their fatty capsule, and brought outside the wound. The 
kidney substance is then cut through and the pelvis irrigated, 
after the removal of the calculi ; at the same time, the ureter 
may be irrigated to remove minute calculi, by forcing them 
into the bladder, whence they can be passed by the natural 
process. To check the bleeding, the cut-halves are merely 
lightly placed in apposition. The kidney is then replaced 
and the external wound closed. R. neither sewed up the kid¬ 
ney nor washed the edges of the kidney wound. 
Autopsy, a few months later, showed the operated kidney 
to be normal in size and a cicatrized line at the site of the 
former incision.— Thiercirzt . Woch. 
HAEMORRHAGIC SEPTICAEMIA IN AN OX. 
This disease is insidious in its onset, and when least 
expected often disappears. A few hours after its onset, the 
animal becomes prostrated, covered with cold sweat, respira¬ 
tion and pulse accelerated, temperature varying from 38.80° 
to 40° C. There is a hollow note on percussing the chest 
and cough weak and infrequent. During the treacherous 
course of the disease, oedema of the lungs and of the glottis 
at the base of the tongue sets in. Lesions at autposy reminds 
one of pleiiro-pneumonia. The lung tissue, instead oh expand¬ 
ing under the influence of air inflations, is solid, inelastic and 
non-crepitating; the interlobular connective tissue is infil¬ 
trated with serum, fibrin and pus, and surrounds red or dark 
lobules of lung tissue. 
These lesions, which have their site chiefly in the middle
