crumbling of the horn. In examination for soundness, the shoe 

 should be taken off, as the morbid horn can only be found on the 

 removal of the shoe. 



196. False Quarter is the result of some extensive damage done 

 to the coronary band, or horn secreting body, from such as stabs, 

 treads, quittor, &c. It is known by a thin layer of modified brittle horn 

 on the hoof, chiefly on the sides, when the parts are constricted, and 

 form, where it is connected to the ordinary horny hoof, rifts or furrows, 

 (resembling sandcracks) on each side ; and at times it may overlap 

 the normal part. A horse with false quarter may work equally as well 

 as one with a good sound foot, and without showing signs of lameness 

 if properly shod ; but great care is, however, necessary in shoeing. 



197. Thrush is the term apphed to a foetid discharge from the cleft 

 of the frog, varying in character. Some formations of feet are more 

 prone to this than others. It is generally produced by the animal 

 standing in a wet, filthy stable or box, and can exist without causing 

 any lameness whatever ; in fact, I cannot call to mind a single case of 

 lameness that could be attributed to thrush. If neglected, however, 

 it may run on until it implicates the sensitive parts, and destroys the 

 healthy growth of horn. A change on to good dry bedding, in the 

 first instance, bathing the parts nightly with salt and water, and 

 dressing with equal parts of Iodoform and Charcoal mixed and pressed 

 into the bottom of the frog cleft with a flat stick — or squeezing 

 a little calomel into the cleft — will generally have the desired effect. 

 Neglected thrush may run on into that formidable disease called 

 canker. 



198. Canker. — This is a morbid fungoid growth of horn at the 

 bottom of the foot, implicating the sensitive sole. It may be produced 

 by injuries, also by standing in a filthy, wet stable, or box, &c. ; greasy- 

 legged horses being very prone to it. Instead of the ordinary horn, 

 little soft, spongy, sprouting growths, of a greyish white appearance, 

 are seen, which bleed on the slightest touch. It is usually first noticed 

 in the commissures involving the bars and frog, and it may extend all
