DISEASES OF HORSES. 213 



substances, and if corn be actually necessary, let it be bruised. 

 Whenever an old horse betrays symptoms of want of condition, or 

 weakness and emaciation, that neither his mode of feeding nor his 

 ratio of work will account for, and particularly if whole grains 

 should be found in his dung, his teeth should be examined care- 

 fully. This undue wearing of the teeth occasions another evil often, 

 which is ulceration of the cheeks, by reason of the projecting ragged 

 surface of the uneven teeth, which can only be remedied by the 

 removal of such portions. These projecting portions are called by 

 farriers, wolve's teeth. 



Diseases of the Neck. 



28. Fistulous withers are brought on usually by pressure from a / 

 saddle with too low or narrow a tree, and what has been said both 

 with regard to prevention and cure on the subject of poll-evil, ap- 

 plies here also. (116.) 



29. Sore throat is common to horses in colds, in influenzas, and 

 in strangles. (13, 22.) In every case, the horse finds great difficulty 

 in reaching every thing that stretches his neck downwards or up- 

 wards, his water therefore should be held to him, and his hay should 

 be pulled for him ; omission of these services greatly aggravates 

 the sufferings of horses labouring under sore throat. 



30. Swelled Neck. A very serious swelling sometimes follows 

 on bleeding with a rusty or poisoned lancet, or fleam, and some- 

 times from causes not apparent. (126.) 



The Chest. 



31. Inflammation of the lungs, is a disease to which 

 the horse is peculiarly liable, as we might a priori 

 suspect, from the vast dimensions of his circulatory 

 system, and the vast alteration from a natural state to 

 which we subject him, and thereby increase his pul- 

 monary circulation. 



32. The causes are these deviations remotely, but the immediate 

 attack is generally brought on by sudden cold, acting on a heated 

 surface, and thus it is that knackers, and collar makers in frosty 

 weather expect a glut of horses that die from this disease. Hard 

 riding is a very common cause, and high feeding also ; it often 

 commences slowly ; a hard dry cough has been slightly noticed, but
