SECRETION OF MILK IN FOALS.

tried to compress them, he caused milk to flow, and the half 
of a small glassful was obtained on milking each of them. 
This milk was examined six hours afterwards, and it appeared 
of good quality ; it was white, had a sweet taste, analogous to 
that of the mare. This secretion ceased on the third day ; 
the fillies showed no signs of disturbance in their health. 
“ M. Mazure, who was the first to observe this phenomenon, 
found the mammae in a filly foal of the size of two fists. 
They were hard, hot, and painful ; the skin tense and shining ; 
the teats prominent. The milk extracted appeared to the sight 
and taste identical with that of the mother. The left gland 
was larger and hotter than the other, and furnished more milk. 
This engorgement of the glands interfered with the move- 
ments of the limbs. This condition of things, which was 
perceived two or three hours after parturition, was overcome 
by emollient lotions, repeated five or six times daily, and by 
frictions with a sedative ointment. But all did not go on so 
satisfactorily as in Lecoq’s cases ; as this secretion of milk was 
associated, in Mazure’s case, with inflammation of the mammae, 
ending in suppuration. A superficial abscess formed in the 
left mamma ; it was opened, and about a glass and a half of a 
yellowish-white curdled liquid, like bad milk, was obtained. 
The cellular tissue which surrounded the mamma was 
destroyed ; the gland separated from the skin became also 
detached from the abdominal walls, by destruction of its 
vessels, and it was therefore floating in a mass of puss. It 
was extracted on enlarging the external orifice, which had 
been formed for the exit of the pus. Fifteen days afterwards 
the skin was again united, and M. Mazure says, that, to his 
astonishment, milk still flowed from the teat. The supposed 
milk was no doubt nothing else than the pus secreted by the 
internal surface of the fibrous capsule, or of the skin which 
had not yet completely cicatrized.” 
A case precisely similar to the last one has been placed 
upon record by Mr. M. F. Wagstaffe; the subject was an 
infant twenty-five days old, both of whose breasts secreted 
milk, and subsequently became the seat of acute abscesses.

In the Comtes Rendus of the French Academy of Sciences 
(vol. 37, 1853 , p. 609) j are the conclusions arrived at in an 
able memoir by M. Natalis Guillot, who founded it upon 
observations of secretions of milk from the mammary glands 
of thirty- nine male and thirty-four female infants. He has 
demonstrated that the phenomenon usually manifests itself 
from the seventh to the twelfth day after birth, and continues 
several days, the mammary glands being in the meanwhile
