40 
showed that they also corresponded to eases of uncinariasis. A family 
of 10 members was selected and examined carefully. Specimens of 
feces from 4 of them were examined microscopically and found to 
contain hundreds of eggs of Uncinaria americana. The owner of the 
plantation in»formed me that it would be a waste of my time to exam- 
ine the remaining 40 “hands,” as the}^ were in exactly the same con- 
dition as the 20 already examined. 
Driving to a neighboring farmhouse, 1 found a family of 5 members, 
3 of whom presented such severe and typical symptoms that I had no 
hesitation in diagnosing them as due to uncinariasis. 
Kershaw County. — While driving back to Kershaw, I passed a 
country schoolhouse. The children, about twenty-five or thirty in 
number, were at play during recess, and a mere glance at them was 
sufiicient to show that 30 to 40 per cent presented the same general 
appearance as the children on the neighboring plantation. 
At Kershaw several extreme cases were met on the street. The 
persons in question had come in from the countiy. One farmer, living 
about 9 miles away from Kershaw, had with him two of his children. 
He stated that his entire, family, 10 in number, had suffered or were 
suffering in the same way as these two boys. Physical examination 
made uncinariasis probable, and the microscopic examination of the 
feces' showed heavy infections with Uncinaria americana. 
Inquiiy among the local physicians and the more intelligent laity 
elicited the information that the cases that 1 had seen represented 
conditions which were usually attributed to “dirt-eating,” “resin- 
chewing,” “heart disease,” “bloat,” “amenorrhea,” “anemia due to 
malaria” (mosquitoes were noticeable chiefiy by their absence), 
“general debility,” “poor nourishment,” etc. I was further 
assured that these conditions were general throughout this region, and 
were not, or only slightl}^, amenable to treatment. 
Taking these cases together, some forty or fifty in all, which I 
examined carefully within three da^^s, we have one common symptom, 
namely, anemia^ nearly all other symptoms noticed could be reduced 
to sequelae of anemia j further, in every case examined microscopically, 
exceedingly heavy infections with ZTncinaria americana were found. 
Under these conditions, and because the general clinical history corre- 
sponded so well with uncinariasis, I have not the slightest hesitation 
in grouping the cases observed as due to Uncinaria americana. 
Chariest 071.^ Chanleston County. — Through the kindness of Drs. John 
Dawson and Robert Wilson, jr., I was able to meet the students of 
the Charleston Medical College. Explaining the object of my- trip, I 
asked for volunteers to submit to microscopic examination. Sixteen 
of the students and 1 member of the facult}^ immediatel}^ volun- 
teered. Of these 17 men (all white, of course), 4 were found infected 
with Uncinaria ainericana and 1 showed a heavy infection with
