EXTRACTS FROM EXCHANGES. 
clein not only destroys disease germs, but also acts as a food 
or stimulant to those organs in the body which normally fur¬ 
nish nuclein to resist invading germs.— Chem. Gaz. 
TUBERCLE BACILLI IN BUTTER. 
A few years ago Heim proved that butter produced from 
tuberculous milk contained bacilli, and could produce in¬ 
fection. Bang reached the same conclusions. Roth con¬ 
firmed these observations. Twenty samples of Swiss butter 
were experimented with, of which two contained bacilli; 
Brusaferro of Turin obtained similar results from an exam¬ 
ination of Italian butter.— Schweiz. Aertz . 
CANCER AND PORK. 
Vernuel and Roux are disposed, as the result of ob¬ 
servation and research, to regard cancer as being frequently 
caused by the use of pork. V. declares that he has observed 
in the course of his surgical career that the Israelites, who 
refrain from pork as an article of food, are always refractory 
to cancer, and this idea had presented itself afresh in connec¬ 
tion with two special cases.— Chem. Gaz. 
, A CASE OF COMPLICATED TRAUMATIC PERICARDITIS. 
A six-year-old cow showed outward symptoms of reticu- 
litis. After three days’ treatment there was a marked swell¬ 
ing of the tracheal glands, quickened respiration, accompanied 
by a constant groan ; in the neighborhood of the heart de¬ 
cided evidence of fluid noises. Next day marked increase of 
both rational and physical signs. 
By means of a small trocar and canula, two pints of a yel¬ 
low serous fluid were drawn from the pericardium. The 
next day auscultation and percussion showed the same amount 
of fluid as before the puncture. The cow died the next night. 
Post Mortem .—Considerable fluid in the pleural and peri¬ 
cardial sacs. The left ventricle was firmly bound by ad¬ 
hesions to the diaphragm. In the midst of these adhesions 
lay a large darning needle.— Schweiz. Arch. Thlk.
