temporary pressure, until the frog becomes sound and 

 larger by growth. 



CANKER. This disease is the result of neglect and 

 constant application of filth to the feet, favoured, doubt- 

 less, by deteriorated system or coarseness of breed. 

 Disintegration of horn substance by a septic condition, 

 which eventually involves the soft tissues and bones be- 

 neath, appears to be the real nature of the complaint. 

 The hoof is first softened by saturation with fluid, and 

 becomes spongy, eventually taking the appearance of a 

 fungus partially horn and flesh, which bleeds copiously 

 on the least provocation, and emits a strong effluvia of 

 sulphuretted hydrogen. It occurs in one or more feet 

 at the same time. 



Treatment. Mild cases only are amenable to treat- 

 ment ; in others, the constitution is tainted, and cure is 

 impossible under any system of treatment. Dry packing 

 by tow, so as to induce pressure, has proved as success- 

 ful as most plans. Caustic dressings have been used ad 

 libitum with only questionable success. Laxatives, 

 diuretics, and tonics are needed during the existence of 

 the disease. 



KERATOMA ; Horn Tumours. As a result of pressure 

 from nails in shoeing, tight clips, 

 &c., irritation is induced, and the 

 result is the formation of a horn 

 tumour at the spot, being a diseased 

 growth of the hoof upon the inner 

 side. 



The remedy is common-sense Horn Tumours in the Foot, 

 shoeing. Promote the growth of 

 horn to provide a needful defence ; use fine nails ; fit 

 the shoe to the hoof, hammer clips lightly, as well as the 

 foot, remembering that it is made up of highly sensitive 

 structures in addition to insensible horn. 



SEEDY TOE. This consists of a separation of the 

 horny wall from the horny laminae, being widest at the 

 junction of the sole with the wall, and filled with a 

 grey powder, the result of disintegration of the hoof.
