266 GLANDERS AND FAECY. 



case wliicli occiiiTed about eleven years ago, near Dixon, Lee county, 

 Illinois, wliere I was then ]^racticinp:. A fanner, Mr. B., came to my 

 office with a horse T>'hich he had recently bought, and which was appar- 

 ently suilcring from some pulmonal disorder. The animal was in a mod- 

 erately good condition and free from fever. The morbid symi)toms ob- 

 served consisted in a slightly laborious breathing, a short, dull, but 

 somewhat loose (not dry) cougii, some discharge from one nostril, and a 

 slight swelling of the submaxillary lymphatic glands of the same side 

 of the head. The symptoms, consequently, were the same as are usually 

 observed in pulmoual glanders ; but as none of them were sufficiently 

 devel()})ed or j)resented sufficiently characteristic properties to indicate 

 with certainty the presence of glanders, and as no ulcers — the most im- 

 portant diagnostic symptom of glanders — could be discovered in the 

 nose, I hesitated to make a definite diagnosis, but informed the owner of 

 my suspicion, and advised him to put the horse, if convenient, to hard 

 work for the purpose of accelerating thereby the moi'bid process (if 

 glanders), and to return the animal for further examination within a 

 week or so. A few days afterwards the same farmer came again to my 

 office with another horse with a badly torn eyelid and an inHamed eye 

 for treatment. This latter horse, which. I will call horse No. 2, had been 

 bitten in the eyelid and hatl the same torn by the horse with the suspi- 

 cious symptoms, which I had seen before, and which 1 will call horse No. 

 1. In examining the wound, which probably had been made during the 

 night, I found the borders very much swelled, and the wound and the 

 conjunctiva of the eye in a condition which strengthened my suspicions 

 of horse No. 1 being affected with glanders. Still, by means of a few 

 stitches, I united the margins of the wound as well as circumstances 

 Ijprmitted. After I had performed the operation I examined the horse 

 as to his general health, but especially as to sj'mptoms of glanders. 

 With the exception of some feverish acceleration of the pulse and the 

 very inffamed condition of the torn eyelid and the conjunctiva, no morbid 

 symptoms could be found. The liorse appeared to Ite in good health 

 and free from any respiratory disorder. The next day I saw both horses, 

 Nos. 2 and 1, on B.'s farm, a few miles from Dixon. Horse No. 2 had 

 high fever ; the wound in the eyelid presented considerable swelling 

 and had suppurated; some of the stitches had been torn out ; and a 

 himp of grayish and glassy mucus had accumulated in the inner cor- 

 ner or canthus of the eye. These symptoms, though comparatively in- 

 significant under other circumstances, convinced me still more that the 

 torn eyelid would not heal and that horse No. 1 was affected with glan- 

 ders, and had communicated the contagion to horse No. 2. In the con- 

 dition of horse No. 1 no essential changes had taken ])lace, except per- 

 Jiaps a sliglit increase in the discharges from the nose. About n. week 

 later horse No. 2 ])resented jdnin and unmistakable symptoms of glan- 

 ders, consisting of lameness, swelling of the inguinal glands, copious 

 discharges from the nose, swelling of the subnuixillary glands, and 

 diphtheritic ulceration on the septum. The condition of horse No. 1 was 

 almost unchanged. Both liorses were killed the next day. The post 

 mortem examinat!<m of horse No. 1 reveaie<l, besides the cliaracteristic 

 morbid changes in the hmgs, indicative of pulmonal glanders of long 

 standing, only a few small ulcers high up on the septnni, while horse No. 

 2 showed all tlie esseiitial sympto^ms of fnlly-developed acute nasal glan- 

 ders and of incii)ieut farcy, but scarcely any morbid changes in the 

 lungs. Whether the inoculation with glauders-contagion effected by the 

 biting and tearing of the eyelid constituted the hrsl commnnication of 

 tho contagion to horso No. 2 by horse No. 1, or whether a previous in-
