beneath the hoof threatening its evulsion, and in other cases it 

 extended deeply to the tendons and ligaments. 



Treatment. The main object should be prevention, to be 

 secured by protecting the stock against contact with septic mud, 

 and especially such as is near the freezing point and intermixed 

 with such sharp stones and pebbles as would wound the surface 

 and open channels for infection. When infection has taken place 

 we should seek to limit it by lotions of an antiseptic character. 

 Bandages soaked in a solution of hyposulphite of sodium, i dr. to 

 the ounce will often succeed. A more potent application is 

 iodized phenol, prepared as follows : tincture of iodine 2 drs. , 

 carbolic acid crystals 4 drs., glycerine i oz., alcohol i oz., water 

 8 ozs. When applied on a bandage this may be diluted with 

 water to make i pint. For circumscribed application to forming 

 sores, the undiluted iodized phenol, made of one part each of 

 iodine and carbolic acid crystals, may be applied twice a day with 

 a glass rod. Other favorite applications are a lotion of lead and 

 laudanum ; a saturated solution of boric acid ; ninety-five per 

 cent, alcohol ; a mixture of creolin i part, iodoform 4 parts, and 

 lanolin 10 parts ; ichthyol and collodion ; ichthyol and vaselin ; 

 or iodol, iodoform, salicylic acid or resorcin as dusting powders. 



Internally, tincture of muriate of iron 3 drms. every three 

 hours helps to keep the affection in check. 



CONTAGIOUS FOOT ROT IN SHEEP AND CATTlvE. 



Definition. A chronic infectious ulcerative disease of the in- 

 terdigital structures and subcorneal tissues of the foot, determined

 iler). 



History. Footrot is described by Chabert as prevailing, in 

 1 79 1, on the low damp lands north of the Pyrenees and later by 

 Pictet, Gohierand others along the rich alluvial river- bottoms 

 in France and other parts of Europe. It was first noted in 

 Merinos, and extending in the line of their diffusion, was thought 

 to be peculiar to this breed, but wider experience showed that the 

 long wools possessed no complete immunity, though there seemed 

 to be a somewhat lessened receptivity for the infection. The
