THE IMPROVED aRT OF FARRIERY. '^7 



with the head held up to a full light, more particularly 

 towards the sun when shining, it may be detected 

 if within any moderate distance ; and when it cannot, 

 the varied appearance of the discharge will bespeak it. 

 The junior practitioner must not, however, allow por- 

 tions of the secreted matter which may adhere to the 

 surface to mislead him into a belief of existing ulcera- 

 tion ; he should, when in doubt, pass up his finger, or 

 a probe armed with tow, and wipe away such : and 

 had not the error actually occurred in the practice 

 of more than one veterinarian, I should be almost 

 ashamed to insert a caution, that the opening of the 

 nasal duct may not be taken for a chancre. The 

 situation of this opening is found a little way up the 

 nostril on the reflected skin, and not on the mucous 

 secreting surface. At an uncertain period of this form 

 of the disease, occurring sometimes much sooner than 

 at others, the lungs become tubercular, and hectic 

 symptoms follow the bursting or ulceration of them ; 

 large vomica also form and burst ; and now the health 

 is evidently fast impairing : there is cough, loss of ap- 

 petite, emaciation, and weakness in the loins ; the hair 

 feels dry, and falls off on being handled ; the matter 

 from the nose increases in quantity, becomes sanious, 

 stinking, or bloody, and is couched up by the mouth 

 also ; and in the expressive words of M. Dupuy, * The 

 animal has a bloated aspect ; the cellular tissue pits, 

 the conjunctiva is infiltrated, the caruncula lachrymalis 

 discoloured, the eye has the expression of a sheep 

 suffering from the rot, the gums are pallid, and the 

 under eyelid of the affected side juts into a prominent 

 circle of duplication. If put to hard work, such horses 

 rapidly decline in condition ; and yet, should they be 

 destroyed, fat is found in abundance upon the belly 

 and about the heart/ '*
