EXTRA-UTERINE GESTATION IN A SHEEP. 
M. Sausol, V. S. ISth Chasseurs. 
A EWE of three years old had taken the ram with the others. 
About two months afterwards the shepherd perceived a small 
tumour, of the size of a nut, about an inch behind the navel.. In 
five or six months it had become as large as a goose’s egg. M. S. 
then saw it. It had the appearance of an abscess. He lanced it. 
A quantity of purulent matter flowed from it, and in this matter 
the bones of a foetus. They were separated from each other, and 
of a black colour. The head was entire, and not larger than a 
filbert. 
M. Saussol then laid the animal on its back, enlarged the inci¬ 
sion, and very carefully examined this artificial uterus. The ab¬ 
dominal muscles were twice their usual thickness, and formed a 
pouch in which the foetus was lodged. Not the slightest com¬ 
munication with the abdominal cavity could be detected. The 
wound was healed in fifteen days. The ewe had not at any time 
appeared to suffer from the formation of this abscess; but after 
the operation its health declined, and it was sold.

ELECTRICITY OF THE BLOOD. 
# 
M. BELLINGERI (Annali Univers di Med. April 1827;, has 
discovered that the venous blood in oxen and sheep, has, in health, 
a degree of electricity equal to that of iron. Exercise, the 
seasons of the year, or the different conditions of the atmosphere, 
have little influence on this electricity ; but that age diminishes it 
iri a small degree, and that it is likewise diminished in inflam¬ 
matory diseases. • ■ • 
The venous blood of horses and dogs does not contain so much 
electricity, and resembles that of antimony. 
Arterial blood contains a rather smaller proportion of electricity, 
and is likewise a bad conductor of electricity. 
* Both arterial and venous blood retain the same quantity of 
electricity after they have been drawn from the vessels, and the 
serum and cruor separated.
