DISEASES, DEFECTS, ETC. 97 



Unsoundness nor a Vice; but if suspected, a special warranty 

 should be taken against it. 



The Parotid Gland is placed in the hollow which ex- Parotid 

 tends from the root of the ear to the angle of the lower ^V^^^ "^*'®' 

 jaw. In bad Strangles, and sometimes in violent cold, it 

 will swell to a great size and ulcerate ; or an obstruction 

 will arise in some part of the duct, and the accumulating 

 fluid will burst the vessel, and a fistulous ulcer will be 

 formed, very difficult to heal. Such a disease is an Un- 

 soundness (n). 



The point of juncture between the head and the bone Poll-evil, 

 nearest the skull is called the Atlas, and is the seat of a 

 very serious and troublesome ulcer termed Poll-evil, 

 caused by the horse rubbing and sometimes striking his 

 Poll against the lower edge of the manger, or hanging 

 back in the stall, and bruising the part with the halter ; 

 or from a violent blow on the Poll, carelessly or wantonly 

 inflicted, or perhaps by unnecessary tight reining ; the 

 consequence is inflammation, and a swelling appears, hot, 

 tender and painful. The swelling increases, and matter is 

 formed, which spreads around and eats into the neighbour- 

 ing parts (o). This disease is an Unsoundness. 



The sensible and horny little plates of the foot, which Pumiced 

 have been elongated and partially separated during the ^^ " 

 intensity of an attack of inflammation, will not always 

 perfectly unite again, or will have lost much of their 

 elasticity ; and the coffin bone, no longer supported by 

 them, is let down and presses upon the sole, which yields 

 to i,his unnatural weight, and becomes convex or rounded, 

 and thus, coming in contact with the ground, it gets 

 bruised and injured {p). This is called Pumiced-feet ; it is 

 incm-able, and is decidedly an Unsoundness. 



A Horse will sometimes partly chew his hay, and suflter Quidding. 

 it to drop from his mouth. This is called Quidding, and 

 proceeds either from irregular teeth or sore throat, but 

 ceases when these are remedied {q) . It would be a symptom 

 of Unsoundness while the sore throat lasted. 



Quittor is an Unsoundness. It has been described as Quitter. 

 being the result of neglected or bad tread or Over- 

 reach (r) ; but it may be the consequence of any wound 

 in any part of the foot. In the natural process of ulcera- 

 tion matter is thrown out from the wound ; this precedes
