ABSCESS IN THE GUTTURAL POUCHES. 



These are two cavities situated above the throat and peculiar 

 to soHpeds. Each has a small opening at its anterior part, 

 through which any liquid within them can escape only when 

 the head is depressed. Hence a collection of matter in these 

 sacs, consequent on a sore throat, escapes and is discharged 

 through the nose intermittently when the head is down drink-

 or fed from the ground, and treated with some of the tonics 

 recommended for chronic catarrh or glanders. But should,

 daily with a weak astringent lotion. This operation requires 

 the most accurate knowledge of the parts, to avoid the many 

 important structures in the region. (See the author's larger

 removed by surgical means.

This appears mainly in cold, damp, marshy situations, where 

 the vitality is impaired, or in unusual seasons. In the cold 

 early summer of 1875 I met with it in cows in several marshy 

 places. Low, damp river-bottoms are most subject to it, and 

 probably it is due to deleterious agents taken in with the food 

 and water as well as to chills and exposure.
