 was found to be decayed and the cavity partially 

 filled with undigested food. After proper prepara- 

 tion of the animal by dieting, he was thrown down, 

 and while under the influence of chloral, the diseased

 bulging nasal bone was then trephined, and about

 turbinated bone with a spoon probe. He was then

 with luke-warm water from a small pipe which was 

 inserted through the opening made by the trephine, 

 the water that entered being allowed to escape 

 through the nostrils, carrying with it small pieces 

 of detached pus. 



This treatment was kept up twice daily until 

 scarcely any discharge was noticed, after which the 

 irrigations were not as frequent, taking place but

After the discharge had ceased the oakum was

The tooth cavity was kept as clean as possible 

 after the extraction, by washing out with water the
