216 VETERINARY DENTAL SURGERT. 



this form of the disease that the long bones, and 

 those too which possess the greatest amount of 

 cancellated tissue are most affected, as shown by the 

 extensive tendinous rupturing which occurs only 

 partially, if at all, in those subjects developing the 

 facial enlargements early and rapidly. 



The rami of the inferior maxilla will be found 

 much larger than in other instances, and it will be 

 important to here state that this bone in all cases 

 invariably gives evidence of the existence of the 

 disease, by an increase of its transverse diameter 

 when no other symptoms are sufficiently developed 

 to testify to its positive existence. The solution of 

 this at first seemingly strange fact is easy, since we 

 know this bone to possess the greater amount of 

 cancellated tissue of any, where examination is not 

 prevented by its protection of muscular tissue. The 

 superior maxilla together, I will repeat again, with 

 every bone in the osseous frame, hyoides included, 

 are at this very time affected, but do not show evi- 

 dence from the reason already given. Indeed, it is 

 a disease peculiar to bone only, and you should not 

 be misled by the rupturing of the tendons and 

 muscles, as this is due to the necrosed condition of 

 the bones at the points of their attachments, and not 

 to any altered condition of their fibers. If the maxil- 

 laries are much affected and the molar teeth be 

 examined, especially the upper, by placing the fore-
