of a rubber bulb syringe, the end of which is introduced between the 

 cotton and the foot. This dressing is to be left in place for from seven to 

 ten days without being disturbed. Unless complications arise, such as 

 swelling above the bandage, the longer time is to be preferred. At the 

 end of this time the dressing is to be removed, and if any pus is still pres- 

 ent the bandage is to be applied as before; otherwise the foot is now 

 washed with a 1-500 bichloride solution, thoroughly dried, and then 

 dusted with a powder consistiag of equal parts of iodoform and tannic 

 acid. The same powder is freely applied to a large piece of cotton and 

 the foot again bandaged and coated with tar. The foot is now left undis- 

 turbed for two weeks. At the end of this time another dressing of iodo- 

 form and tannic acid may be made if necessary. As a rule, however, 

 little need be done at this time except to provide some protection to the 

 newly forming horn. This may be accomplished by means of a leather 

 sole placed underneath the shoe. 



The keynote of success in following this method of treamtent lies in 

 the complete removal of all portions of horn that have become under-run 

 with pus, and the thorough cleansing and asepsis of the foot. 



The following cases are described as illustrative of this method of pro- 

 cedure, and show what may fairly be expected in the way of results: 



Case A. — A large gelding, which had the history of going lame suddenly 

 on the right hind leg, and was unable to bear weight upon the same. There 

 was also considerable swelling above the hoof, extending upward as far as 

 the fetlock joint. Subsequent examination showed that all of the frog 

 and fully half of the outer portion of the sole was under-run with pus. 

 All such portions were completely removed and the foot bandaged in 

 a bichloride solution as described. The owner was directed to pour some 

 sublimate solution, into the top of the bandage twice daily. In a week 

 this bandage was removed, the foot again washed in a sublimate solution, 

 thoroughly dried and dressed with a powder consisting of equal parts of 

 iodoform and tannic acid. This bandage was left in position for ten days, 

 and as at the end of this time new horn had formed to replace that which 

 had been removed, he was taken to the farrier's and a shoe applied with 

 a false sole of heavy leather underneath it. The horse was now allowed 

 to resume his work of plowing. 



Case B. — This case is reported in order to show what untoward results 

 may follow what is too often considered an unimportant injury. A mare 

 sustained a nail prick of the frog, involving the underlying sensitive 

 structures. No attention was paid to the case until the pain had become 

 so exquisite that she was unable to bear any weight upon the affected 

 leg. Examination showed that the frog had become under-run with pus 

 and that the region of the fetlock was very badly swollen. On remov- 

 ing the frog a relatively large amount of pus escaped. The foot was 

 trimmed out, cleansed an4 bandaged in a bichloride solution, the applica- 

 tion of tar, however, being omitted. The owner was directed to give noti- 

 fication of any further attention seemed necessary. Evidently not being 

 satisfied with the way the foot was doing, and probably largely influenced 

 by outside opinions, the owner had the bandage removed and a cow- 

 manure poultice applied to the entire foot. Within a few days after this
