the indications present, was pursued, but notwithstanding the best 
care, the animal died within a few hours. At the post moitem 
every thing was found in proper condition on the left side, but 
on the right there appeared a soft, piriform irreducible tumoi, 
formed by the vaginal sac and containing a portion of strangu¬ 
lated small intestine, evidently a lesion which had taken place 
during the struggles of the animal while under operation, which 
at the time was entirely overlooked.— Ibid.

BACTERIOLOGICAL RESEARCHES IN TETANUS. 
By Lampiasi (of Trapani). 
The author reports that he made cultures of the bacillus of 
tetanus in using the material obtained from a man that died of 
spontaneous lockjaw, and from two mules, one of which died, while 
the other recovered in twenty-seven hours. 
These cultures showed that the microbe in its full develop¬ 
ment has the form of a bacillus, straight, very seldom curved, or 
divided into small cylindrical fragments. At the period of spor- 
ification it is at times fusiform and granular in aspect. The spore 
is a large elliptical cell, with two short filiform prolongations, 
visible only in the dried preparations. 
Upon agar and gelatine the microbe gives whitish colonies, 
rounded, resembling a drop of wax, and becoming yellow after 
two or three months. 
.Forty-five guinea-pigs, seventeen rabbits, two lambs and one 
sheep were inoculated. Of these, twenty-seven died from tetanus, 
twelve had the same disease and recovered, and ten died from 
acute infection, without tetanic manifestations. 
To resume : 1st.—The micro-organism of lockjaw is a specific 
bacillus, identical in its form either in man or in animals. 
2d.—This bacillus is very easily cultivated from the blood of 
affected subjects, either accidentally or artificially inoculated. 
3d.—Spontaneous tetanus is produced by the same organism 
as that of experimental lockjaw. 
4th.—Traumatic tetanus is, in all probability, produced by 
the same micro-organism.— Surg. Cong, of Naples , C. R.
