one-fifth of the soldiers in the national encampments 

 in the United States during that summer developed 

 this disease, while more than eighty per cent, of the 

 total deaths were caused by typhoid. 



About the same time that Doctor Vaughan's report 

 was presented, Dr. R. H. Quill, in a ''Report on an 

 outbreak of Enteric Fever at Diyatalawa Camp, Ceylon,

During the Boer War again and again the connec-

 tions from different writers of that period. These may 

 be quoted as follows: 



"Tooth and Calverley (1901, p. 73), writing of ty-
