Blood . — I did not stop fo’’ blood counts, as these have been made 
by other men, and while they are exceedingly interesting from a path- 
ological standpoint they have not appealed to me as so direct a method 
of diagnosing intestinal parasites as is the fecal examination. In gen- 
eral it may be said that the blood of man corresponds to the blood of 
sheep, goats, cattle, dogs, etc., suffering from the same disease; in 
other words, the severer and longer the infection, the thinner the 
blood. In the vernacular of the sandlapper, it is ‘4ike water.” It 
may here be added that in early literature on dirt-eating, several 
authors remark upon the water-like appearance of the blood. 
Speaking in more technical language, the blood has been shown by 
Ashford to possess the following characteristics: 
‘‘(1) A severe anemia, falling as low as that of Addison’s anemia in count of red 
cells in some cases. (2) A very low hemoglobin average and a very low color index. 
(3) A marked eosinophilia in some cases; 40 per cent reached in one case. This 
follows the observation of Xeusser. (4) Xo leucocytes common to the disease itself. 
Leucocjdosis recorded is always apparently due to complications, as noted. (5) Fre- 
quent presence of normoblasts, and in some cases megaloblasts, but never a majority 
of megaloblasts. (6) Poikilocytosis common. Manson denies this.” 
Ashford gives the following interesting table of blood counts:
