rice polishings, red rice being then substituted, for the reasons 

 already stated. 



The experiments were continued for as long a period as prac- 

 ticable. When a prisoner insisted upon being returned to the 

 regular prison ration or his condition became such that such a 

 change of diet seemed advisable, the experiment in his case was 

 discontinued. 



Several attempts were made to secure skiagrams of the hearts 

 of the individuals, but the electric instalment in the prison was 

 such that satisfactory X-ray photographs for publication could 

 not be secured. For the same reason the testing of the elec- 

 trical reactions of the patients, which was attempted during the 

 experiment, was unsatisfactory, and we could not secure a satis- 

 factory, suitable, and portable electric apparatus for this pur- 

 pose in Manila. As these prisoners were all under sentence of 

 death, they could not be taken outside of the prison for any pur- 

 pose. The prisoners are referred to by numbers. With the 

 history of each case is given a curve of the weight during the 

 experiment and there is placed after the last case in each group 

 a table showing the amount of food consumed each day. All 

 of the prisoners were healthy at the time of the beginning of the 

 experiment and had been under observation for some weeks. 

 None of them gave a history of having suffered with beriberi 

 previously. A summary of the important features of the his- 

 tory of each individual who partook of the diet will now be 

 considered. 



SUMMARY OF THE RECORDS OF THE CASES OF GROUP I. 



CASE NO. 1 (GROUP l). 



Diet: White rice + rice polishings" for 13 



days followed by white rice + extract of 



polishings for 95 days, together with the 



special diet common to all the groups. 

 Dried codfish and potatoes were added to the diet on the 97th day 



Total period of experi- 

 ment, 108 days. 



Following is a summary of the notes of the case: The exam- 

 ination showed an apparently healthy individual; percussion 

 and auscultation of the chest revealed no abnormality of the 

 lungs; the examination of the heart showed no increase in the 

 area of cardiac dulness beyond the normal limits; the point of 



" The cases in Group I were fed rice polishings for 13 days as a suf- 

 ficient amount of the fresh extract of polishings was not prepared at that 

 time with which to begin the experiment satisfactorily.
