Albany, Dougherty County . — Leaving the sand district I next visited 
Albany, which is surrounded by clav. Corresponding to tlie change 
in the soil there was a change in the medical facies, rncinariasis 
disappeared, except for cases which came in from the neigh bori fig 
sand districts, while malaria increased. Dr. Ililsman, one of the local 
physicians, kindlv drove around with me to lind Cfises, but we wm-e 
obliged to go about 15 kilometers (0 miles), namely, into Lei‘ Countv, 
before we located a familv with uncinariasis. l)urin<r this drive we 
left the cla}^ soil and passed into a sand district, with jiine woods. 
The family in (question presented four typical extreim' cases; although 
microscopic examination for sake of diagnosis seemed uniu‘c(‘ssary it 
was nevertheless made and show^ed heavy infection with Utteinuriu 
amerlcana. 
While with Dr. Ililsman in Albany I made a most fortunate mistake 
in diagnosis. The patient was a l)oy about 13 or 14 years old. He 
had a clear case of malaria (tyjiical histoiy, enlargi'd sj)l(*en, etc.), but 
in addition to that 1 was confident that he had a medium or light 
infection with uncinariasis. Microscopic examination proved me in 
error. This boy lived in a clay district and had never lived in sand; 
furthermore, he did not show the eye s^uuptom, which I slmll discuss 
later (see p. 05). This is the last time I attempted a detinit(‘ diagnosis 
upon symptoms of ain^ medium or light case unless si'vere cases 
occurred in the same famil 3 ^ 
As soon as Dr. Ililsman understood the kind of cases 1 d('sir(‘d tt> 
see he stated, with the utmost positiveness, that they did not arise in 
and around Albany until the sandy soil was reaclu'd. ( )ccasiofially 
cases came to Alban}’ from the neighboring sand coimties, but the 
local anemia Dr. Ililsman considerc'd to be almost (uitirely of malarial 
origin — an opinion in which 1 can only concur aft(‘r what 1 saw in 
that city. 
I happened to be in Albany on Saturday, when the country folks tor 
miles around come to town. Standing on the stre(‘t conuu’ for sev(‘ral 
hours, I must have seen about whites and fully 3,ni)0 ni'groc's who 
drove or walked into town. Of the whites, I notic(*d about 5 cases of 
probable uncinariasis. Two of the cases, whom I was able to inter- 
rogate, gave a typical history of unciiniriasis (‘XttMiding back tor several 
years, but no history of malaria. Tln'v came from neighboring sand 
counties. Among the 3,0(M) negro men, wonuni, and childrtm, whom 
1 saw, there was only one pei’son in whom 1 i‘V('n susjx'cted troin his 
general appearance that uncinariasis might be pi’i'siMit. 
Willacoochee^ Coffee County . — In southern ( b'orgia, Cotb'e Oounty 
bears the reputation of being more or l(\ss a centi’r tor dirt -I'aters. It 
is a sandy, pine-wood district, with numerous swamps, which indicate 
a more impervious subsoil. As a result, l)oth malaria and uncinariasis
