"Our Medical School has just begun again, and I have one nice class of sixteen students who are going to devote themselves to the study of applied physiology, and all of them will experiment on the effects of thorough mastication in relation to the quantity of food; also in relation to the quantity of proteids. If you would like the details of the results of the experiments, I will give them to you later. "By the way, if you have any written or printed outline of data which you think it desirable to collect, I will be glad to have it as a help to us in researches of this sort. We have prepared our laboratory to do almost anything that needs to be done, and we have a whole lot of enthusiastic young men and women who will enter into this thing with great zeal, and we will be glad to coöperate with you thoroughly as I feel that you have introduced a line of research and investigation which is of immense importance. I have read with great interest Prof. Chittenden's article in the _Popular Science Monthly_, and I can but feel that you are a heaven-sent missionary to the world in this matter of diet reform. "I remain, "As ever your friend, "J. H. KELLOGG." "P. S.--I have for many years given a good deal of attention to the matter of mastication. It has been my regular prescription for all my patients for many years to eat at the beginning of each meal some Granose Flakes. The purpose of this was to secure increased activity of the salivary glands, and to encourage the habit of mastication. I have found immense benefit from this practice. "I appreciate exceedingly all the good things you are sending me. What a delightful time you must have had in the Adirondacks! I have never had such a pleasure in my life, as I have had my nose continually on the grindstone at work since I was ten years of age, with no vacations at all. It is a remarkable spectacle that these great men, these learned professors and scientists, and army medical men, should be coöperating so enthusiastically with a layman to learn the true philosophy of life; but it has always been so. The great discoveries have not been made by great scientists and great doctors, but by men whose minds were above the bias of prescribed education, and who were able to learn from the great book of nature, which is the book of God. "When you come again I hope you will have time to stay with us a little while so we can have some good chats. I would like to sit down and go into the heart of things with you, when I think we should find our ideas running very close together. We shall expect to see you next month. I have to be away for a few days sometime during the month, so I hope you will let me know a little while before you come about what time to expect you. "J. H. K." EXTRACTS FROM DR.
