180 VARIETIES OF GLANDERS. 



instance suspected or asserted to be glanders, a searching, satis- 

 factory inquiry. Numbers of horses — of valuable horses — no 

 doubt, have fallen sacrifices to the ignorance or precipitancy of 

 their medical attendants : a more skilful and thorough investigation 

 of their cases, greater patience, allowing for the development of 

 symptoms, would have shewn where the errors lay, and have 

 saved, as well as many lives, the veterinary practice of days gone 

 by a load of opprobrium since passed upon it. 



VARIETIES OF GLANDERS. 



Whatever division we may make of glanders — whatever 

 kinds or species we may distinguish in it, we must bear in mind, 

 the disease in nature remains the same. The varieties of aspect, 

 of intensity, of duration, observable in it, are attributable to the 

 part in which the disease is seated, to the stage through which it is 

 passing, to the age, state, &c., of the patient, and to other cir- 

 cumstances, which in their proper places will hereafter receive 

 notice. We might found our division upon the circumstance of 

 glanders being seated at one time within the nose, at another 

 within the sinuses of the head, within the lungs, within the 

 larynx. We might distinguish as species or varieties the different 

 appearances the disease assumes even in the same part, which we 

 now regard as stages ; such as the first or incipient stage, the 

 ulcerative, the sloughing or typhoid stage, &c. To both these, I 

 prefer the division based upon the intensity and duration of 

 glanders, as the one which will be found most useful to us in 

 practice, and which has this advantage over the two others we 

 have noticed, that, although the three varieties will be found 

 ruiming into each other, yet no sooner does a fresh species make 

 its appearance than that which existed before necessarily ends. 

 According to notions that have grown up in my mind, after an 

 observation of many years of glanders in all its forms and phases, 

 the best division we can, in my opinion for practical purposes, 

 make of the subject, is into acute, sub-acute, and chronic : the first, 

 comprising such forms of the disease as rapidly and uninterruptedly 

 run their course and end in death ; the second, such as present the
