ouly occurs at a late stage of the disease ; since I found it to occur as 
frequently in early, as in late cases. 
With regard to the connection which exists between infection wdth 
this parasite and the albuminuria and cardiac dilatation so frequently 
found associated with its presence, I made notes on a consecutive series 
of 172 cases in which one or both these symptoms occurred. The 
results were as follows : 
Albuminuria. 
(a) Associated with ankylostomiasis ... ... 52 
(5) Not „ ,, ,, 9 
Cardiac dilatation. 
(a) Associated with ankylostomiasis ... ... 70 
(6) Not „ „ ,, 2 
Albuminuria and cardiac dilatation. 
{a) Associated with ankylostomiasis . 37 
(&) Not ,, „ ,, 2 
From this table it will be noted that whereas in 1.59 cases of the 
series the parasite was found to be present, it was only absent in 13; 
in other words the association was one of 92 "/o, a percentage out of all 
proportion to the degree of incidence which we know to obtain amongst 
the sick population generally. 
These results also disprove the theory that prevails with regard to 
the causation of the caj'diac dilatation being the result of arduous 
labour in a hilly country. The hills undoubtedly play a part, but only 
that of aggravating an already diseased organ, not of causing tbe 
disease. 
A series of tw'enty-five blood examinations was also made from the 
members of this series, and the results obtained are tabulated below. 
I should, however, state that all the specimens examined were taken 
from cases in which the disease was advanced and the anaemia extreme. 
The average of the counts was as follows : 
Bed cells . 1,26.5,000 
White cells ... ... ... 10,000 
and the average percentage of haemoglobin was 20‘5. 
The differential leucocyte count was as follows : 
Polymorphonuclears ... ... ... 49'5 % 
Eosinophiles ... ... ... ... 22-4 % 
Lymphocytes ... ... ... .. 15-8 '’/q 
Mononuclears . ... ... 7-6%
