later than those of the facial artery. By auscultation, a vi¬ 
bratory fremitus is heard analogous to the vibrations heard with 
the phonendoscope when auscultating an animal which trembles. 
This fremitus is louder at some moments than at others.

Caries of the Right Branch of the Inferior Maxif- 
FARY, AfVEOEITIS, AND CARIES OF THE TWO FlRST CORRE¬ 
SPONDING Moears [By Rousselot and Sanary ].—A four-year- 
old colt received a kick on the right side of the lower jaw. 
A trauma resulted, which was treated with simple antiseptic 
treatment, there being no fracture. There remained, however, 
a thickening which was rebellious to all treatment, and the 
primitive wound assumed the aspect of a fistulous injury, which 
on being explored revealed a manifest carious condition of 
the maxillary bone. Treatment was immediately instituted ; 
free incision of the fistulous tract, and antiseptic dustings, with 
liquor of Van Sweiten and iodoform gauze. At first this 
treatment seemed to succeed, and it was thought that the 
continuation of injections of cresyl and dusting of iodoform 
would be followed with recovery. However, the improvement 
was temporary, and another probing of the wound revealed that 
the first lower molar was diseased. A small splinter of bone 
was removed ; there was a characteristic odor; the case was not 
only one of maxillary caries, but complicated with alveolitis 
and dental caries. Severe surgical interference imposed itself, 
with all its dangers, principally that of possible fracture of the 
jaw bone. This, however, was decided upon, the animal cast 
and secured, the parts disinfected, the maxillary exposed by V 
incisions, and trephined on the two tangent places in such a way 
as to reach the roots of the first two molars. Once the external 
plate of the maxillary was removed, an escape of greyish sani- 
ous, nauseous pus took place, fragments of the maxillary and of 
the roots of the teeth were removed, and finally, not without 
difficulty and great care, the first tooth was extracted with nip¬ 
pers, the second gouged out. The after treatment consisted of 
injections of weak cresyl solution, iodoformed gauze in the 
wound and suture of the cutaneous wound. The food was 
made of soft liquid mashes and gruel. After two weeks the 
fistulous wound was considerably reduced, and a month after 
the operation the animal was discharged radically cured.— (Rec.
