predisposition. Cornet once attended, in a hotel, an 

 actress far advanced in phthisis. A guest taking pos- 

 session of her room after her death, or removal, might

 room being unknown, the case of such a guest would, 

 in all probability, be referred to predisposition. It 

 might be declared, with perfect sincerity, that for years 

 he had had no communication with phthisical persons. 

 There is very little doubt that numbers of cases of 

 tuberculosis, which have been referred to predisposition

 tion in some such obscure way. 



Cornet draws attention to hotels and lodging-houses 

 at, and on the way to, health-resorts. He regards them

 regarding the precautions taken to avoid infectious 

 diseases, tuberculosis among the number. The atten-

 spit upon the ground.' 



With regard to the permanence of the tubercle con-

 who had for two years suffered from a phthisical cough, 

 and who had been in the habit of spitting first upon 

 the ground, and afterwards into a glass or a pocket-
