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- 

 ter diverging from its roots and extending irregularly 

 through its entire substance. The fiicial 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 tilled with a deposition 

 of a fibro-cellular structure.

 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
