 in the intensity of the functional disorders and 

 the cadaveric lesions to which it gives rise. The 

 typhoid fever, we mean the real one, for there 

 are other intestinal exanthematic fevers which 

 simulate it, always localize on the small intes- 

 tines a pustulous exanthem, and in the typhus 

 of the ox, this pustulous exanthem and the 

 ulcerations by which it is succeeded, are fre- 

 quently wanting. 



The real typhoid fever springs up in every 

 country under the influence of local causes, 

 and is not in the same degree infectious and 

 contagious as the typhus proper. In fine, the 

 typhoid fever smites many species of animals 

 the horse, the pig, etc., without transmitting 

 its contagion with the same intensity. 



The contagious typhus of the ox appears to 

 be more especially proper to that animal ; for 

 in those latitudes where it developes itself 

 other animals are not affected by it. 



For these reasons, then, to which we could 



easily add many others, we consider the typhus

type of typhic diseases, and differing from the
