uterus, when it becomes necessary to stimulate its expulsive 
efforts in the delivery of the placenta, after parturition. 
Employing for the purpose the syringe of Pravaz, he accord¬ 
ingly caused the injection upon the surface of the vagina and of 
the neck of the uterus, or in that organ, a preparation * of two 
grainms of an alcoholic solution of veratrine to 1-25, and as the 
result, was enabled to witness an accession of repulsive efforts, 
which continued for more than two hours. The consequence was 
the elongation outwards of a part of the placenta, and five hours 
later, the adhesions of the cotyledons having given away, a slight 
traction on the part was sufficient to remove the entire mass. 
The process of cleaning the parts, always repulsive and often 
dangerous, is now avoided in Germany, and instead of it, the 
uterus is filled with blood-warm water containing an alcoholic 
solution of corrosive sublimate, the process being usually success¬ 
ful. Failure in favorable results rarely occurs .—Annates de

APPLICATION IN THE PROPHYLAXY OF ANTHRAX, OF THE 
METHOD OF ATTENUATION OF THE VIRUS BY 
COMPRESSED OXYGEN. 
By Mr. A. Chatjveau. 
A long-continued series of experiments has led the author to 
the following conclusions : 
First .—A single inoculation confers perfect immunity. 
Second .—Notwithstanding this activity in the virus employed, 
it is as inoffensive as that prepared by the other methods. 
Third .—The cultures maintain their qualities for several 
months, without requiring any special precautions for their pres¬ 
ervation. 
Consequently, a single inoculation is sufficie t to insure the 
immunity of animals, and to protect them efficacious^ against 
either experimental inoculation with strong virus or the effects of 
spontaneous contagion. 
Again, cultures attenuated by the action of compressed oxygen 
are as inoffensive as very attenuated cultures obtained by the
