222 DISEASES OF THE HORSE. 



ance of the running from the nose, which has become more glu- 

 tinous, and adheres to the edges of the nostril with a contraction 

 and partial closing of the nostril, an increased tenderness of the 

 swelling under the jaw, whicli begins to adhere more closely to 

 the jaw-bone. In the third degree, the running from the nose 

 becomes of a darker colour, sometimes streaked with blood, and 

 of an offensive smell. There is sometimes a bleeding from the 

 nostril. The running is from both nostrils. There is a slight 

 tumefaction of the under eye-lid, a swelling or elevation of the 

 bones of the nose or forehead. Loss of appetite, debility, cough, 

 and swelling of the legs and sheath, or testicles, if a stallion ; also 

 lameness without any apparent cause. Chancres or ulceration 

 within the nostrils, great tenderness of the glands under the jaw, 

 Avhich now stick close to the bone. A small discharo;e of matter 

 fi'om the inner corner of the eye on the same side as the affected 

 nostril, or in both eyes, when the running is from both nostrils. 

 When these symptoms appear the disease soon proceeds to a fatal 

 termination. The above symptoms are not all peculiar to 

 glanders, but may take place also in strangles, bastard strangles, 

 peripneumony, distemper (^morfondnre) and pleurisy. The dis- 

 charge of a glutinous matter from the nose, the swelling of the 

 glands under the jaw, and the ulceration within the nostrils are 

 symptoms which occur in the above diseases as well as in glanders, 

 but with this essential difference. In the latter, the three 

 symptoms just noticed generally occur about the same time, 

 which is not the case in glanders ; and are, in the first instance, 

 acute and inflammatory, and such as to excite apprehension of 

 immediate danger. They go through their course in a short 

 time, the running from the nose gradually diminishes, the blood 

 is depurated, and a perfect recovery takes place. Glanders, on 

 the contrary, is extremely slow in its progress : the first degree 

 often continuing a considerable time ; and it is only towards the 

 end of the second degi-ee, or the beginning of the third, that 

 the symptoms appear to indicate an alteration, or disease of the 

 internal organs. This slow progress of glanders, and especially 

 its continuing for some time without any apparent injury to the 

 animal's health and condition, the state and progress of the 

 swelling under the jaws, and the ulceration within the nostril, 

 furnish such clear marks of distinction between those diseases 

 and glanders, that they cannot well be mistaken for each other." 

 It is a remarkable circumstance that glanders cannot be com- 

 municated by applying the matter which is discharged from the 

 nose of a slandered horse to the nostrils of a sound horse, unless 

 there be an open wound or sore, even though a piece of lint 

 soaked in the matter be put up the nostrils, and kept in contact 

 with the pituitary membrane for a short time ; or even if the
