Preparation of Foods. — My method of preparing the sonp, the chief 

 nitrogenous food of the day, was as follows : — 20 grams of jnlienne 

 were weighed out the night before, and set aside in a dish, and covered 

 with about 250 c.c. of water to soak. By 6 p.m. on the following day 

 it was sufficiently soaked to be ready for cooking, and was then 

 poured into a saucepan, care being taken that none either of the 

 vegetable or water was lost. To this was added salt and dried meat 

 (60 grams), and the whole boiled for twenty minutes or half-an-hour, 

 and kept constantly stirred, so that nothing should adhere to the 

 sides of the saucepan, get burned, and so be lost. When suffi- 

 ciently cooked it was poured into the basin from which it was to be 

 eaten, and the saucepan carefully cleaned with a little boiling water, 

 which was then added to the soup. By these precautions I found no 

 difficulty in securing the consumption of the whole of the material. 



The potatoes were cooked according to the directions given by the 

 makers, a small portion of fat being added. I found that when 

 properly cooked there was not the slightest difficulty in removing 

 them from the saucepan completely. 



The apples were stewed in the dish with the water in which they 

 were soaked, together with the 15 grams of sugar, and from this dish 

 they were eaten, so that nothing was lost. 



Remarks on some Considerations involved in the above Diet. 



My diet during these experiments was compared with my ordinary 

 food, a very concentrated one, and on this ground alone it has been 

 suggested to me that it was very objectionable, and could not nourish 

 me in the same way as my ordinary food. To this 1 can only reply 

 that during the whole course of these experiments I enjoyed 

 exceedingly good health, and provided I was careful about my diet 

 for a few days after the conclusion of an experiment, I experienced 

 no ill effects whatsoever; on the contrary I have found on several 

 occasions that my general health was decidedly benefited by adopting
