CONSTANT PHENOMENA 



or they might grow and multiply amongst the epi- 

 dermic cells or epithelial cells of mucous membrane, 

 and cause small collections or flakes of these to be 

 detached from time to time. It is probably in this 

 manner that the poison of scarlatina is discharged 

 from the infected organism. Protected by the scales 

 of cuticle amongst which it has grown, it may retain 

 its vitality for a length of time. 



From animals which have died of the cattle plague, 

 I have been able to obtain specimens which show 

 very conclusively the manner in which the escape of 

 the particles of contagious bioplasm is effected. In 

 Plate XXVII are represented several papillae from 

 the mamma of an animal which died of the disease. 

 All the capillaries contain the bioplasm which makes 

 its way from them into the epithelial texture above, 

 in the manner represented in the outline drawing, 

 Fig. no. In 113 many of the bioplasts are actually 

 seen amongst the epithelial cells. The bioplasm of the 

 cells is also enlarged from the accompanying fever 

 and inflammation, and in some cases pus was almost 

 produced, Fig. in. See also pp. 190, 218. Among the 

 softened and altered cuticular cells sporules of fungi 

 may often be detected, Fig. 1 12, but these have nothing 

 whatever to do with the disease. 



The constant phenomena of Fevers and Inflamma- 

 tions. Although the subject of fever and inflam- 

 mation is far too extensive to be discussed here, 

 my work would be incomplete if I omitted to refer
