CAUSES OF GLANDERS. 199 



and, so far as making out seven kinds of glanders and admitting 

 but one out of the seven to be contagious, he certainly was so. 

 This one contagious species of his, it must, however, be remembered, 

 was farcy-glanders ; the very species we of the present day 

 call true or confirmed glanders ; and so, according to these views, 

 Lafosse did not deny the contagiousness of glanders, although 

 he held the opinion that the disease rarely arose out of such a 

 cause. 



BOURGELAT, 1765, the founder of the French Veterinary 

 School at Lyons, evidently entertained notions opposite to those 

 ^ of Lafosse. He thought that horses exposed to contagion did not 

 at all times take the disease. His words are, " according to the 

 acridity of the virus of glanders, as well as according to the greater 

 or less disposition of the sound horses to take it, will be its con- 

 tagious effects; and sometimes no such consequences will follow." 

 This opinion, remarks Gohier, from whom this account is taken, is 

 conformable to the observation of the present day*. 



GUERINIERE, 1769, concurs in belief with Solleysell, that 

 glanders may readily be propagated within stables through the 

 medium of the atmospheret. 



GarsauLT, 1770, is of opinion that the malady will be caught 

 by licking the discharges from a glandered horsej. 



DUTZ, 1773, a Dutch veterinary writer, published some observa- 

 tions leading to the inference that the contagiousness of glanders 

 was matter of doubt*. 



LAFOSSE,y?mzor, 1775, was an affectionate copyist of his father^. 



VlTET, 1783. — " Should a sound horse be made to live with one 

 virulently glandered, he would soon take the disease. In mules 

 the disease makes great ravages, and is readily communicable. It 

 is more contagious in summer and in hot stables than in winter or 

 out-of-door situations. Some farriers think a horse cannot take the
