Delivery in a Cow of a Viable Fcetus on the 221ST 
Day of Gestation [By M. Capitaine \.—The size of the product 
of this premature delivery was in proportion with its develop¬ 
ment, its skin was covered with very short hairs, the horn of its 
toes was soft, a rudiment of vulva and of mammae indicated 
its sex. Unable to rise or to stand, it seemed full of life, 
and was artificially fed by the owner, about a pint of milk being 
given night and day, five times in the twenty-four hours. After 
eight days it was able to get up but not strong enough to stand,

Ocular Prothesis in the Horse—New Operating 
Process. —In II Nuovo Ercolani Mr. O. Vigezzi recommends 
the placing of the artificial eye only three or four weeks after 
the enucleation of the natural eye, that is, when all inflammation 
has subsided. But at that time, the eyelids are more or less 
drawn into the orbital cavity, and it may be very difficult to fix 
the artificial eye. To avoid this difficulty, the author has had 
eyes prepared, one temporary and one permanent. The first 
is pierced with four holes in cross, three of which are of 
even diameter, the fourth, the lower one, a little larger ; to per¬ 
mit the introduction of antiseptic powders, and drains of hydro- 
phylous cotton. The superior is covered by the upper eyelid 
and allows the irrigation of its internal face. The two lateral 
give passage to rubber draining tubes, carrying holes in the por¬ 
tion corresponding to the concave surface of the eye. Thus pre¬ 
pared, the apparatus is put in position as soon as the diseased 
eye has been removed and the cavity has been antiseptically 
dressed. The after care consists in washing the operated region 
as follows: Before all, clean the drainage tube with a sublimate 
solution and then introduce through the lower opening of the 
artificial eye phenicated cotton. After the washing of the 
drain, it is closed with forceps or with the fingers to prevent the 
escape of the solution, except through the superior or the lower 
opening. The excess of the liquid which may remain in the
