EXPERIMENTS ON CAMPHOR. 
bowels followed. M. Prevost was called in when the horse w as 
dying*. The canal of the ureters w as lined with a yellow*, hard, 
tendinous membrane, which crepitated under the knife. Its thick¬ 
ness varied from three lines to two inches. At a little distance 
from the place w here we usually find the sphincter of the blad¬ 
der, the canal of the ureter bifurcated. One led to a reservoir six 
inches in length and four wide, which was the bladder. The 
walls were an inch in thickness, and the internal membrane 
presented several black spots as large as a franc. The muscular 
membrane, the only one that was thickened, was composed of a 
ligamentous, cartilaginous tissue, crepitating under the scalpel. 
The arteries w ere in their natural state. The other branch also 
bifurcated, after it had been continued about an inch, and ter¬ 
minated in two pouches less extensive than the first, elong*ated, 
and having some resemblance to the very large finger of a glove, 
These he considered as supplementary bladders. 
The above is a most extraordinary account: it is not related 
with the accuracy of an anatomist; and a contemporary French 
editor very shrew dly asks, might not these supplementary blad¬ 
ders be the vesiculi seminales displaced, enlarged, and in a mor¬ 
bid state?

Experiments on Camphor. 
By M. Dupuy. 
Camphor, administered internally, whether in a state of pow¬ 
der, or dissolved in fixed oil, or in the yolk of an egg, is consi¬ 
dered as an antispasmodic and sedative. In large doses it is 
said to be stimulant, and might cause death by^ acting on the 
brain, or inflaming the digestive tube. In the second volume of 
the Materia Medica of Bourgelat, camphor is called a sedative. 
It is employed in acute diseases, dysenteries, fevers ; it is also 
recommended for inflammatory tetanus. Under the form of a 
soft paste made with a small quantity of spirit of wane, it is used 
when the capsule of the coffin-joint is opened. It is also re¬ 
garded as an incisive, and as a resolvent, in cases of contusion 
and of recent tumours : it is said to be given in doses, from two 
drachms to two ounces to large animals, and from half a drachm 
to four drachms to small ones. 
Cullen assures us that it is very difficult to determine what are 
the virtues of camphor, on account of the various contradictory 
opinions which are entertained on that subject. This opposition 
of opinion proceeds from the belief that it is sometimes a stimu¬ 
lant and sometimes a sedative. He says that, introduced into 
the stomach, it acts in a singular manner, as it were bv some
