SWALLOWING A DISEASED TOOTH. 187 



such an extent as to displace the eyeball. The outer 

 surface of the diseased mass was soft in texture. It 

 had a gelatinous appearance, and when pressed with 

 the blade of the scalpel, a thin, watery fluid oozed from 

 its surface. A section of it presented a grayish-red 

 appearance, with lightish streaks of fibro-osseous mat-

 through its entire substance. The facial bones them- 

 selves, in the region of the disease, had in some parts 

 disappeared altogether, while in others the cancelli 

 were much enlarged, their osseous partitions partially 

 absorbed, and their interstices filled with a deposition 

 of a fibro-cellular structure. 



" Such is a brief outline of this malignant and in-

 from caries of the roots of the grinder teeth." 



Prof. Renault, of Alfort, France, is the author of an 

 interesting account of a very unusual case, namely, 

 the swallowing of a diseased tooth by a horse, which 

 appeared originally in the " Recueil de Medicine Vete-

 horses for the purpose of extracting their teeth, for 

 had the horse been in a standing position the accident 

 would not have occurred. When a horse's head rests 

 upon the occiput, the muzzle pointing upward, it is as 

 natural the tooth being free of the forceps as well as 

 the socket for it to drop into the throat as it is for 

 water to run down hill. The full history of the case 

 is as follows : 



" A post-horse, seven years old, had not fed well, and 

 had been losing flesh during about three weeks. On 

 the 26th of November, 1835, I saw him for the first 

 time. The postilion told me that within the last two
