EXTRACTS FROM FOREIGN JOURNALS.

gland about as large as you would expect to find on a pony with 
.first foal; the teats as large and long as the first joint on the little 
finger, and from which I quickly extracted about half a pint of 
milk, or fluid very much like it, a small quantity of which I send 
for your inspection. During twenty years’ practice in an agricul¬ 
tural district I have neither seen nor heard of anything like it 
before. 
My advice to the owners was to relieve the gland occasionally, 
and if it became tense and painful to foment with warm water. I 
also advised a brisk dose of castor oil and that the mare be kept in 
and on dry food. 
The fluid referred to was of a dull greyish-white hue; specific 1 , 
gravity 1030; reaction to test paper, neutral. It presented r/ m 
opaque appearance, but in a less degree that ordinary milk. x On 
being allowed to stand, a thin layer of cream rose to the surfface; 
examined with the miscroscope, milk globules were seen ihu large 
numbers. The addition of acetic acid caused the fluid h Jo assume 
a more dense white appearance and to throw down a .^finely granu¬ 
lar precipitate. 
Lactation in infancy is by no means a rare occurrence in the 
human subject, but we do not remember to have met with a case 
in the lower animals, where this function wa&, so prematurely and 
freely exercised. / 
Since writing the above, Mr. Freer reports : The foal is going 
on well. Tlje gland has wasted considerably, but for more than a 
week after I wrote you the milk was often seen running away 
from it.— The Veterinarian. 
PATHOGENIC MICROBE OF INFLUENZA. 
By the Same. 
Cultivations have been made with the fluid extracted from the 
lungs of diseased horses, with the pleuretic exudate, the nasal 
discharge and the blood. As elements of culture, gelatine, serum 
of the blood of horses and slices of potato have been used. Six 
varieties of microbes were obtained. The one which he considers 
as being t^ e germ of influenza forms cultures whose coloration
