bacillus, is however, so readily destroyed by thorough desiccation that this mode of transmission is exceptional. Some men are immune to glanders, and suffer only when predisposed through a course of ill health, and yet a large proportion of the cases on record have been in strong hearty men. _Symptoms of Glanders in Man._ In man as in the horse, glanders occurs in the _acute_ and _chronic forms_. In the _acute_ supervening on an external inoculation, _incubation_ is from one to four days. When it enters through other channels it may seem to extend to a week or more. When a skin abrasion has been inoculated it will show in a few days a soft inflammatory swelling or a firm nodule with a puffy reddish areola, and it may be mistaken for a carbuncle. In not a few cases the small nodule has been mistaken for small pox. In my experience a horsemen on a ranch on which over a hundred horses showed glanders, died of an ulcerous skin affection which was variously supposed to be a malignant small pox and measles, though neither malady was known to exist in the district. Other cases are confounded with gangrenous erysipelas. The absence of these other affections from the locality, and the fact that the patient was employed about glandered horses, should go far to correct such mistakes. The early supervention of ulceration is further diagnostic, and discovery of the bacillus mallei in the products will be conclusive. From anthrax it is easily distinguished by the absence of the dark centre of the sore in the early stages, and of the large sized bacillus anthracis. The caseation or liquefaction of the necrotic centre further distinguishes it from the characteristic anthrax slough, and the thickening and induration of the lymphatic walls are not present in anthrax. Sometimes the inoculated case proves mild and recovers in two or three weeks with healing of the ulcer, but in other cases there is an extension to adjacent tissue and a general infection with the supervention of nasal glanders. There is a spread of the erysipelatoid inflammation and swelling, and the formation in such newly invaded tissue of nodules and ulcers in successive crops. In acute cases too, the nasal mucosa becomes involved with the formation of the nodules and ulcers that are so pathognomonic in the horse. The discharge is then somewhat sticky and often tinged with blood. In acute cases according to Senn, the nose may be completely destroyed and deep facial ulcers may be formed in a week. The submaxillary glands are enlarged and painful and the facial lymphatic vessels leading from these to the nose may be red, thickened and tender. Suppuration and ulceration of the glands may ensue. Headache, prostration, nausea, inappetence and vomiting with diarrhœa usually supervene. Then follow dyspnœa, wakefulness, troubled dreams, anxiety, nocturnal delirium, stupor and coma. The pulse may rise to 120 and the temperature to 104° F.
