Modification 

 of the Course. 

 The clinical 

 picture de- 

 scribed may 

 show marked 

 modifications. 

 The disease 

 may become 

 checked in any 

 stage of its de- 

 velopment, and 

 pass on to re- 

 covery. On the 

 other hand in 

 some cases m 

 the early stages 

 the original 

 disease, to 

 which purpura 

 hemorrhagica 

 forms a sequel, 

 may yet per- 

 sist; but in a 

 still greater 

 number of 

 cases the 

 disease itself 

 may be changed 

 by the appear- 

 ance of compli- 

 cations arising 

 during its de- 

 velopment. 



One of the 

 most frequent 

 complications 

 i s pneumonia, 

 which usually 

 is lobular in 

 character, and 

 develops in 

 connection with 

 hemorrhages 

 into the lung 

 tissue ; and may 



be, less frequently, the result of the aspiration of necrotic parts 

 of mucous membrane, assuming then often a gangrenous form.
