I in the same famih^ or neig’hborliood with severe cases. The l)est and 
! most relialde method of diaonosis is ])v fecal examination, althoii^di in 
blood examination increased eosinophilia indicates tlie ])Ossibilitv of 
intestinal parasites. 
First of all let us recall that uncinariasis is a possil)ilitv which should 
be considered in connection with all cases of anemia, especially anion^r 
earthworkers, as in miners, brickmakers, canal dio-aers, farmers, etc., 
or in persons returning from the tropics, and amon^^ persons who have 
a history of residence on sandy soil. Three methods of fecal examina- 
tion are open to us — the blotting-paper test and the microscopic and 
the gross examinations. 
BLOTTING PAPER TEST WITH FECES. 
For persons who are not in a position to make a microsco])ic exami- 
nation, the blotting-iiaper test (referred to on p. bi)). will be found 
very useful. To make the test, use only fresh feces. Place an ounce 
or more of the stool on a piece of white blotting papi'r (an}" absorlumt 
white paper will answer the purpose); allow it to stand for twenty to 
sixty minutes; remove the feces and examine the color of the stain. 
In about four out of five cases of medium or severe uncinariasis, the 
stain is reddish broAvn and immediately reminds one of a blood stain, 
hi making this test on anemic patients, piles should of course be 
excluded. 
It developed in my work in the Virginia penitentiary, that this test 
is open to error in dealing with criminals. In order to avoid wcirk, 
convicts, especially hard-labor contract convicts, occasionally produci' 
a hemorrhage purposely by wounding the mucosa of the rectum by 
means of some sharp instrument.
