previous to the head being thus tied, and the introduction of air 
rendered impossible. 
Finally, M. Bouley, while he thought that his case could 
only be considered as one of the series which M. Amussat had so 
clearly illustrated, could not admit with M. Bouillard that it 
presented nothin ^particular, A pathological fact which verifies 
the truth of a chirurgical principle, hitherto demonstrated by 
experiment alone, seems by this very circumstance to offer some- 
thing that is particular . This fact is otherwise an important 
one, for according to it, of all those that have been cited in vete- 
rinary medicine, in this alone the air entered the vein at the mo- 
ment that the opening was effected ; while in the other cases 
that are reported, this fluid does not enter the vein until the com- 
pression of the vein and the consequent issue of blood have ceased. 
It was regarding it in this double point of view that M. Bouley 
thought it a case of some interest. He hoped and believed that 
he w r as not deceived, and that the Academy would not repent of 
the time that was devoted to it.
