114 VETERINARY LECTURES 



It is due to some injury done to the foot — such as laminitis, or too 

 much pressure by the clip of the shoe— and is mostly found at the 

 toe of the fore-foot, but may occur at other parts of the hoof as well. 

 The hind-foot may also be affected. When seedy toe is suspected, 

 the shoe should be removed, and all the degenerate horn cleared out 

 with a fine-pointed shoeing-knife ; then some stimulating dressing 

 should be applied, nothing being better than the tar ointment recom- 

 mended for sandcrack (par. 193). Tar by itself must never be 

 used, as it is too stimulating, and causes a 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. 



195. False Quarter 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, and is the result of some extensive damage 

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

 stabs, treads, quittor, etc. 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. 



196. Thrush is the term applied 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 pioduced 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 neg- 

 lected, 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 char- 

 coal mixed — or a little calomel — and pressed into the bottom of the 

 frog cleft with a flat stick will generally have the desired effect. 

 Neglected thrush may run on into that formidable disease called 

 canker.
