occurrence which has been observed by MM. Cadeac 

 and Malet. Inter-sexual and intra-uterine contami- 

 nation are, however, actually of rare occurrence. 



Indirect contagion is much the most frequent. The 

 glanders virus, distributed externally, contaminates 

 the food, drinkins: water and litter, harness, groom- 

 ing utensils, sponges, brushes, curry-combs, etc., the 

 walls of houses, mangers, racks, and such like; if 

 it meets with the conditions necessary for desicca- 

 tion it will be carried with the dust into the sur- 

 rounding atmosphere. The morbific germ is trans- 

 ported on to the healthy organism through the in- 

 termediation of numerous vehicles. Infection mav 

 take place through the respiratory passages, the ani- 

 mal inspiring air charged with virulent particles, bnt 

 this mode of contagion should be rarely effective in 

 glanders since desiccation is a puissant cause of the' 

 destruction of the bacillns. The disease is more cer- 

 tainly communicated by the digestive. canal, through 

 swallowing infected food or water. This contamina- 

 tion of the ingesta may result from their immediate 

 contact with the products coming from a diseased 

 animal or it may occur during their storage in in- 

 fected places. 



In this connection should be mentioned the danger 

 arising from the consumption of animals which have 

 died or been killed while suffering from the disease. 

 This danger exists not only for the specific lesions, 

 in which the virulence is evident, but also for the 

 flesh. The investigations of MM. Cadeac and Malet 

 have shown that the juice of such flesh is capable of 

 communicating glanders. 



Finally, the virus may penetrate through the skin
