     These observations were most carefully carried out and are absolutely reliable.
They confirm the results already obtained from work on prisoners. Another
point of importance noted was that both Assistants got diarrhœa when 20 and 15
grms. of NaCl were added to their diet. Large quantities of salt have a well-
known tendency to hurry on the food materials by increasing peristalsis of the
bowel. This in itself is an indication for the cutting down of the very excessive
quantity of salt given in the jail diets—25 grms.

     5. Investigations on five Bengali prisoners as to the elimination of salt
when the quantities of Burma rice and Mung dal varied in each diet.

Diet I.

Burma rice . . . . . . . 26 ozs. observed for four days.
Mung dal . . . . . . . 6 "
    Total intake of salt = 485.00 grms.  
Output in urine . . . . . . . 414.45 grms.=85.4 per cent.
" in fæces . . . . . . . 10.92 " =2.2 "

     leaving 12.4 per cent. eliminated in sweat or 2.98 grms. per man daily.

     This corresponds with the results obtained on a similar diet in Puri Jail
giving an average of 0.54 grm. in the fæces.

Diet II.

Burma rice . . . . . . . 16 ozs. observed for six days.
Mung dal . . . . . . . 8.4 "
    Total intake of salt = 718.10 grms.        
Output in urine . . . . . . . 632.35 grms.=88.06 per cent.
" in fæces . . . . . . . 26.46 " = 3.7 "

     leaving 8.24 per cent. eliminated in the sweat.

     This means 0.88 grm. NaCl per man daily in the fæces, a higher figure than
is usually obtained.

Diet III.

Burma rice . . . . . . . 32 ozs. observed for six days.
Mung dal. . . . . . . . 4 "

          Total intake of salt =638.10 grms.

Output in urine . . . . . . 536.25 grms. = 84.04 per cent.
" in fæces . . . . . . 11.40 " = 1.78 "

     leaving 14.18 per cent. to be eliminated in sweat.
