CONTRIBUTIONS TO ZOOLOGICAL PATHOLOGY. 
doubted; but something more than this must have been in operation. 
Wherever there was a projecting point on the skeleton, that part 
had more the appearance of a rough nodulated coralline, than the 
usual muscular impressions that are there seen. They were not 
the result of domestication, but of often-repeated and long-con- 
tinued injuries inflicted on the enduring and patient animal. 
The surface of the bones of the muzzle was still more changed 
in appearance. From the edge of the orbit on either side to the 
point of the muzzle above, and from the incisor edge of the sym- 
phisis menti backwards to the edge of the masseter muscles, there 
was one continuous mass of effused and organized callus. This 
consisted of several layers, imposed on each other in a very irre- 
gular manner, and giving this part of the face more the appearance 
of a madrepore than of a smooth bone ; and, what was strange, the 
bulk of the exostosis was situated around the exit of the superior 
and inferior maxillary nerves. On the right side especially the 
terminations of both these nerves were completely obscured at 
their exit by irregular knobs of callus, and the branches that 
proceeded to the whiskers and lips were hid in small canals of ad- 
ventitious bone. On the right side of the lower jaw there was a 
cloaca the size of a pistol bullet, and out of which had been exfoli- 
ated a portion of the bone forming the outer crust of the alveolar 
socket for the laniary tooth. Indeed, the cavities for all the laniary 
teeth presented considerable evidences of the morbid action that 
existed without, having extended itself to their very sockets — cir- 
cumstances which I doubt not would give rise to a considerable 
degree of loss of power in these teeth, even though the animal had 
been enraged, and had attempted to immolate his master. The 
entire substance of the superior and intermaxillary bones shewed 
the same evidence of disease. The cavities in the interior of the 
former were almost filled up, and the whole of their nasal surfaces 
were nearly as rough with effused callus as their exterior. Alto- 
gether, the entire muzzle presented evidences of most extensive 
morbid action having been present, and that for a considerable time. 
The dorsal surface of the metacarpal and first row of phalangeal 
bones of both paws were also covered with numerous ossific points, 
evidently produced by the same causes as those operating on the 
cranial; and at all the other projecting points in the osseous struc- 
ture of the anterior extremities the same appearances were ob- 
served. 
From all these circumstances, therefore, we are constrained to the 
conviction, that had “the rod been spared, the child would have 
been spoiled ;” and whatever other means may have been adopted 
to curb the impetuous passions and feelings of the animal, still 
those of physical force must have been used as an extensive and
