A. had nothing to say when I told him that I did not hold by either high or low proteid but only by my appetite and taste, developed by ample mouth opportunity to discriminate, which I hoped, in time, to understand more thoroughly than I do now. He told me that he feared that there would be great physical deterioration after a long period of low proteid. I said that I did not believe it would be the case by your method. For instance, right in the midst of a long period of most satisfactory low-proteid supply, I once ate nearly a whole chicken with some ham at Penegal. I could not get saliva for anything else.[2] In short, then, I insisted only on thorough mastication to protect taste and appetite, and had no other theories. I was only concerned in observing the factors determining my taste and appetite. I would be more than contented to leave the question of minimum and maximum quantity of proteid to be settled in the future after normality had been established by practical demonstration. Yours faithfully, HUBERT HIGGINS. EXTRACTS FROM DR. KELLOGG’S LETTER BATTLE CREEK, MICH. October 7, 1903. MR. HORACE FLETCHER. DEAR FRIEND,--Yours of September 30th just reached my hands and I hasten to reply. I saw a newspaper note in reference to the soldiers which the government has selected for the dietetic experiments, and also read an interesting article in the _Popular Science Monthly_. You have accomplished a great good thing in enlisting these scientific and military men and interesting them in the investigation of this wonderful reform. The marvellous thing about it is that these busy men of science should have so readily undertaken an investigation which involves so much surrender and self-denial, at least, at the start. I know you are absolutely right. My personal experiences and observations confirm me. In the experiments you mention, which I made in reference to the daily ration for ordinary persons, I simply sought to ascertain, as have others, how much and what kinds of food people are in the habit of using, taking no account of the possible excess or the careless manner in which they eat. The figures I got were sixteen ounces of starch; 1.2 ounces fat, and three ounces proteids,--approximately 2,500 calories. In observation of patients I have seldom found one able to eat this amount. Personally, I habitually eat scarcely half as much. My breakfast to-day was the yolks of two eggs, two or three tablespoonfuls of corn flakes, a moderate-sized potato, and a couple of peaches. At dinner I shall take a little more.
