the examination of urine indicate that the European figures are 

 of little value when dealing with Asiatic patients. In Table 7 

 are summarized some of his results which show smaller volumes 

 of urine and lower figures for total nitrogen, chlorides, and 

 phosphates for the Asiatic, as compared with the European. He 

 refers these differences entirely to climatic influence; heat and 

 atmospheric moisture are said to account for the desire to lessen 

 food and work, and the lessening of food brings poor physique 

 and less muscular energy. The students of Singapore, (4) Ma- 

 nila, (l) and the Philippines generally have a smaller protein 

 intake than the European, and this has been accounted for by 

 the fact that climatic conditions require the maintenance of a 

 smaller amount of body heat. Of the three, the Singapore 

 student, with no seasonal change and a mean temperature of 

 80°, eats the least; but we must observe that his protein metab- 

 olism is about the same as that of the Pekingese. 



The diet shown in Table 1 represents the average amount of 

 food per diem taken by ten convalescent surgical patients. The 

 actual amount of protein consumed was considerably less, for it 

 was found that the patients did not actually get the amount of 

 meat reported as being served to them. Hence the value of the 

 report lies in the results of analyses of the daily urines. The 

 diet is shown because, except for the amount of meat, the amounts 

 of foodstuff may be considered accurate and show how other 

 factors were taken care of.
