regard as quittor, it may^ through the want of attention^ 

 degenerate into a true disease of the kind. 



5th Feb., 1826. — A cart-horse belonging to Mr. T. 

 Goding became excessively lame in the near hind foot from 

 a sand-cracky accompanied with irritative fever, which lasted 

 to February 16th, when a portion of the os pedis exfoliated 

 from the midst of fungoid laminse which previously displayed 

 no disposition to heal. From this period the horse became 

 free from pain, and the wound gradually closed. A period 

 of eleven days therefore elapsed, from the occurrence of the 

 fractured hoof to the exfoliation of the piece of bone in appo- 

 sition with the disease. (John Field's ^ Notes.') 



Genuine Quittor essentially consists- in sinus running 

 down between the sensitive parts and the horn. Under 

 circumstances of confinement, the pus contained in an 

 abscess will spread, and produce separation between the horny 

 and sensitive parts. When once disease is established within 

 the foot, one part after another will exhibit it, until the car- 

 tilages and bone participate : the sensitive laminae will ulce- 

 rate ; the elastic structure connecting them to the cartilage 

 and bone will be involved ; finally, the hard parts will inflame 

 and become carious : thus will that which in the first instance 

 was curable, be rendered tedious, difficult, and even doubt- 

 ful. So weak is the vitality of cartilage, that when once 

 inflamed, the diseased portion has little chance of recovering 

 health. Ulceration in such a structure is tardy, often un- 

 toward; keeps up continual irritation, and occasions loathsome, 

 green^ discharges, which in some cases are very abundant. 

 These ravages have been known to make holes through, 

 or to destroy, the cartilage, and afterwards to penetrate 

 the pastern or coffin-joint. So lamentable an event is made 

 known by the augmentation of suffering, and the admixture 

 of synovia with the discharge ; it would certainly call for 

 the knacker, that this personage might take a life which our 

 art could not render otherwise than painful.
