top of the hoof are recommended. The following 

 mixture has been useful as a blister: Red iodide 

 of mercury, I part; lard, 4 parts; cerate of can- 

 tharides, 4 parts. Apply around the top of the 

 hoof, except at the heels, and rub for 10 to 15 

 minutes. The animal should be tied so that it can- 

 not get its mouth to the blistered part for several 

 hours after the medicine has been applied. 



CHRONIC FOUNDER. In a majority of cases 

 the above treatment will be followed by a good 

 recovery, but an animal once foundered is probably 

 more likely to suffer from a subsequent attack. If 

 the lameness does not entirely disappear in a week 

 or ten days, it is seldom that a complete recovery 

 takes place. In such cases the animal is likely to 

 remain unfit for road work and to continue to show 

 more or less soreness. These are the cases that 

 are later said to have " chest founder," or " stove 

 up in the shoulder," owing to the fact that the 

 muscles of the chest waste away from lack of free 

 use. 



In some cases still more serious results follow 

 an acute attack of founder. The inflammation may 

 be so severe that there is separation between the 

 hoof and structures, the formation of pus, and a 

 descent of the central organs of the foot, which 

 causes a bulging of the sole. In such cases, even 

 though recovery takes place to such an extent that 

 it is advisable to allow the animal to live, it is not 

 fit for work, and can only be used for breeding 

 purposes. 



FOWL CHOLERA. See Chicken Cholera. 



GAPES. A symptom caused by worms in the 

 windpipe; oftenest seen in young chicks and tur- 

 keys. Birds droop, cough, and lower their wings.
