"Battle Creek, Mich., Jan. 22, 1903.
"Dear Friend:
"I have your kind note of the 23d inst. I am sure that one of my letters to you has been lost. I wrote promptly telling you that you were at liberty to use anything I have written you respecting your work.
"I am more and more enthusiastic respecting the value of thorough chewing. I have read with great interest Dr. Harry Campbell's articles, and am republishing in Modern Medicine a large part of what he has written.
"I have been thinking whether I might dare ask permission from you to publish your article 'What Sense' as a tract. Possibly it is already printed in that way. I would like to circulate it widely among my patients, and our nurses and doctors. I am doing my best to get them all to chewing, and have had great benefit myself from thorough mastication.
"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,
