were found, and it was exceedinoflv interestine to note the ease with 
which an error in diagnosis in medium and light cases could be made 
if the microscope were not used. Extreme cases, however, coidd l)e 
easily distinguished without the microscope. Several cases of typical 
extreme uncinariasis were seen on the street, but not examined care- 
full v. Then, throusfh the kindness of Dr. TV’ilcox. I was able to make 
a careful examination, both physical and microscopic, of a group of s 
cases at the sawmills a short distance from town. After Dr. AVilcox 
examined these cases with me, he declared that he knew of at least 
similar patients within the teiTitory of his practice. He considered 
this condition one of the most common diseases of that region, but 
thought malaria was fully as common if not more so. 
Ware County , — Passing now to TTaycross. I entered a dis- 
trict where uncinariasis is exceedingly common. Di*s. P. P. Izlar and 
J. L. Walker assured me that the cases I was tracing, two of which 
1 saw with Dr. W alker. were much more common than was malaria, 
the proportion being about '20 to 1. In this district these patients are 
called ” Branch-water people.” Both Dr. Izlar and Dr. Walker stated 
that they could easily show me scores of cases within a radius of a few 
miles. 
FLORIDA. 
JacksomnlJ.e, Duval County . — In Jacksonville two cases of typical 
imcinariasis were seen on the street. One of these patients was traced

Both the State and the city health offices assured me that the condition 
I was hunting was perfectly familiar to them — that it was prevalent 
throughout the State, especially in the "liat- woods district.” and that 
Florida physicians interpreted it as an anemia due to malaria and 
improper diet. 
Waldo. Alachua. f —Through the kindness of the local phy- 
sician. Dr. J. W. Boring. I was able to examine two groups of tvpical 
cases of imcinariasis within a short distance from town. Dr. Boring 
assured me that this condition was exceeding common in Florida and 
was generally interpreted as an anemia due to malaria and improper 
diet. 
Ocala. JIarion County . — In Ocala I saw several typical cases of 
imcinariasis on the street, and. through the kindness of Dr. A. F. Izlar. 
I was able to examine 5 positive cases and 1 probable case more 
closely. Dr. Izlar confirmed the statements of the health offices in 
J acksonville. Fla. . relative to the frequency and intei’p fetation of the 
disease. 
From Ocala I returned (November 16) directly to Washington. D. C. . 
and noticed several cases which presented the appearance I had found 
typical of imcinariasis. as^ the train stopped at various stations in 
Florida,
