a One concurrent infection of Ascaris and Trichuris. 
& Including the cases harboring the mites, which however are not true parasites. 
It is thus seen that while we might expect that our 200 patients 
would show (independently of the fact that they had typhoid) approx- 
imately 15 (14.7) verminous infections, they actually did present 
(despite their typhoid infections) 16 infections (in a total of 15 per- 
sons); 4 additional cases (2 per cent.) presented either live or dead 
mites in the feces, but these may probably be ignored; and 185 
patients (92.5 per cent.) showed no intestinal worms. 
Further, while we might expect that 11 or 12 of the patients 
(11.36 cases, or 5.68 per cent.) would present infection with whip- 
worms (independently of the fact that they had typhoid), 14 patients 
(7 per cent.) actually did have w^hipworms. 
Thus, in the 200 typhoid patients, the increase (over what might 
have been expected had they not had typhoid) w'as only 1.3 infections 
(0.65 per 100 persons) excess in general helminthiasis, and only 1.32 
per cent excess in infection wdth w’hipworms. These slight excesses 
can hardly be considered as of importance in connection with the 
typhoid fever w’hen we recall that 92.5 per cent, of all the patients 
showed no intestinal worms w^hatever, and when, further, we take into 
consideration the unusually wet weather which has prevailed this 
year. 
It is rather interesting that the excess in whipworms was due to an 
excess of infection among the whites, which gave a total of 9.55 per 
cent whipworms against 3.75 per cent which we expected to find. 
Still, this excess of 5.80 per cent, can hardly be considered as of sig- 
nificance in connection with the typhoid when we note that the negroes 
gave only 1 case of w^hipworms, or 0.5 per cent, instead of 6 cases, or 
9.79 per cent., which we might have found wdthout exciting any 
surprise.
