well-developed and well-nourished individuals, all of which except 
one pertain to the first group above mentioned. The rest of 
the cases (six in number) received no mention as to their nutri- 
tional condition. For the sake of clearness, the series may be 
divided into four groups as follows : I, cases which gave positive 
signs of beriberi; II, cases which indicated no reliable history 
of beriberi, but which were undernourished and belonged to 
the poorer class; III, cases which were well developed and 
nourished; and IV, cases regarding whose nutritional condition 
we have no data. 
FINDINGS AND DISCUSSION 
The fifty-eight cases studied, with their short clinical histories 
and the qualitative chemical analyses of their respective calculi, 
are too long for publication in full in this paper. Examples of 
the condensed case histories and chemical findings in only four 
cases, each representing a group, are given to show how the data 
were arranged for presentation in tabular form. 
CASE 63 (group I) 
E. M. (55787), 25 years old, married, male, Filipino, fisherman; bora

diseases. He is well developed but poorly nourished. Signs of beriberi 
present and history of having had the disease is positive.
