228 DISEASES OF THE HORSE. 



and has found that on inoculating a healthy donkey with 

 glanderous matter, it has produced tubercles in the lungs in a 

 very short space of time. 



These views are deserving of great weight, but we cannot 

 altogether coincide with them ; for, although perhaps in the 

 majority of cases tubercles are found in the lungs of glandered 

 horses, yet there are other instances in which there are none to 

 be found there or elsewhere. The particular seat of glanders 

 is certainly the membrane lining the nostrils and chambers of 

 the head, although in a great number of cases the lungs are 

 likewise involved. We cannot say whether in all cases the con- 

 stitution is affected, or Avhether in some instances the disease is 

 entirely local ; but in the subject chosen by Professor Coleman 

 for experiment, it was clearly proved that the blood was infected. 

 There is evidently a much greater predisposition in some horses 

 to receive the disease, either from infection or otherwise. 

 Horses with narrow chests, long legs, and light carcasses, are 

 more liable to take the disease than others ; and some consider 

 that colour has something to do with the matter. Some years 

 since, during my pupillage at the Veterinary College, having to 

 read a paper on glanders to the Veterinary Society, I examined 

 the record of cases kept there for many years, and I found that 

 the number of chesnut glandered horses was greater than that of 

 any other colour. 



Next to that of curing this disease, it is desirable to be able to 

 decide in difficult and obscure cases as to its actual presence ; 

 and on this matter the opinion of veterinary surgeons is fre- 

 quently demanded. Grooms and farriers more frequently give 

 a wrong than a right opinion, imagining when the symptoms are 

 very mild, that the disease cannot be glanders, and often pro- 

 nouncing a horse to be glandered when he has only the strangles 

 or catarrh. The first mistake, however, is the most frequent. 



In examining a suspected case, if we find a discharge of 

 matter from one nostril, and a portion of it sticking to the 

 entrance with a hard and fixed enlargement of the submaxillary 

 gland, although the enlargement may be slight, and the dis- 

 charge inconsiderable, yet, if these symptoms have existed for 

 two or three months or upwards, we may safely decide the case 

 to be one of glanders, even if there be no ulcei'ation within 

 sight. When these symptoms exist, but there is no means of 

 ascertaining the history of the case, we may justly consider 

 that the probability is in favour of its being one of glan- 

 ders ; and this opinion Avill be gi'eatly strengthened if there 

 are any mysterious or suspicious circumstances connected with 

 it, such as the horse having been sold at a very low rate. If, 

 however, Ave cannot trace the history of the case, and the animal 

 is of any value, it will be desirable either to keep it for some
