370 CAUSE OF GLANDULOLS SWELLINGS. [BOOK II. 



ing, or however healthy the previous state of the 

 animal's system, causes the glands to enlarge and 

 inflame; after a while, remaining uncured, they 

 usually adhere to the bone, when alone we should 

 pronounce the glanders confirmed. This becomes 

 " the second species" of La Fosse, which may be 

 communicated by contact, or by respiring the same 

 air — in the stable ; though it does not appear until 

 eight or ten days after the infection, in the enlarge- 

 ment of the gland, accompanied or preceded by 

 running. The third species is caused by farcy 

 being in the system, or by inoculation, in which 

 way the glanders has been communicated by expe- 

 rimentalists : the running at the nose and swelling 

 of the glands are then symptomatic of farcy-glan- 

 ders, and must be treated as such. 



What inference is to be drawn from those pre- 

 mises, but that we should endeavour to ascertain 

 the length of time the patient has been afflicted ; 

 whether he has received any external injury to cause 

 it, or, has he been brought into contact with infected 

 horses, and when ? and out of the answers hereto 

 we form the resolution of condemning the animal 

 to solitary keeping, at the least ; and set about the 

 remedies that are likely to restore him to health. 

 Crowded towns, posting stables, and barracks, are 

 most subject to contain glandered horses, on ac- 

 count of their closeness, and the frequent succession 

 of inmates to which they are liable ; for some 

 horses will bear it for a good number of years, the 

 discharge almost subsiding (though the swelling of
