POWDERY DEGENERATION OF THE DEEP PARTS OF THE WALL. 



SEEDY TOE. 



The result of uneven bearing of the shoe, the formation of 

 furrows between the sole and wall, direct violence, as blows, or 

 the too tight hammering of clips, etc., this is manifested by an 

 irregularity or dryness of the affected part of the wall, and the 

 formation of a cavity, filled with horn powder between the 

 laminse and the wall of the hoof. Clear out the cavity until the 

 tough healthy horn is reached, then fill with warm tar and shoe 

 carefully to give a uniform bearing. A clip may be useful as a 

 support to the undermined horn, but it is destructive to hammer 

 it tight. The dressing must be repeated at each shoeing until 

 the cavity is filled up. 



INFLAMMATION OF THE SECRETING MEMBRANE OF THE FROG 

 WITH DISCHARGE. THRUSH. 



Causes. — Exposure to wet and filth ; standing on dung, or in 

 a dirty, wet yard ; stuffing the feet with cow-dung ; bruises of 

 the frog ; undue paring ; wounds of the frog ; accumulation of 

 dried mud or gravel in the cleft ; extension of disease from the 

 skin of the heel, etc. 



Symptoms. — Foetid discharge from the cleft, soreness of the 

 skin behind this, lameness or not according to severity. 



Treatment. — Wash out the diseased part, pare away all ragged 

 detached horn, and apply some astringents (dry calomel pressed 

 in on a pledget of tow ; tar with a few drops of sulphuric acid 

 on the surface ; carbolic acid ; or finely powdered sulphate of 

 copper or zinc).

This is a more inveterate inflammation of the frog, and it 

 may be the sole, representing in the horn-secreting structures
