For particulars on this point see the chapter on etiology. - {53) More than 90 per cent of the men tuho developed typhoid fever had no preceding intestinal disorder. In 7,745 cases in which this point was especially investigated 7,097 (91.63 per cent) Avere not preceded by any intestinal disorder. {5Ji) The deaths from typhoid fever were 86.2J^ per cent of the toted deaths. {55) The morbidity from typhoid fever per 1,000 of mean strQngth was a little less than one-fifth {192.65).
