Mr. Fletcher's own letter is to my mind a refutation to Dr. Kellogg's claim as to the continuation and increase of autointoxication, for he tells the benefits that he has received during his fast of seventeen days, and those benefits would have been greatly increased if he had continued the fast until his tongue was clean. His sense of taste had become so refined by the fast that his food was more delicious than ever before, which showed that the refining process had been going on all through his body. Another benefit that he mentions is the lessening of his desire for sugar, that he is satisfied with the sugar sweet that is in the food itself, which is so much more healthful than the cane sugar. Another thing that he speaks of is the reduction in his weight, which he needed. I sincerely hope that Mr. Fletcher will fast again, and make it a complete fast, for I think he will have a very different story to tell from what he tells in this letter. CHARLES COURTNEY HASKELL. Dec. 28, 1910. DEAR MR. SINCLAIR,--I have your letter of the 14th inst. and its enclosures. To those who have carefully and scientifically undergone or advised the fast, the cause of the symptoms that Dr. Kellogg and all of the rest of us recognize as indicating self-poisoning, is readily discovered to lie in the inability of the organs of elimination to promptly convey from the body the products of food supplied in excess of digestion. It is a conclusion that cannot be escaped that, when the refuse from broken-down tissue and from food ingested beyond the needs of the body is discharged into the intestines, and when means of removal are not at hand, re-absorption at once begins and continues until the canal is cleansed. Self-poisoning, autointoxication, ensues, and all of its symptoms were emphatically shown in the fast of seventeen days that Mr. Fletcher essayed. These results are also often observed when feeding is in progress, and in this connection I refer to an article written by Dr. Kellogg for _Good Health_ in the summer of 1908. In it he says, "The writer's observations, extending over a considerable number of years, have brought him to the conclusion that the cases which are benefited by fasting are practically without exception cases of autointoxication, generally cases of intestinal autointoxication, though perhaps also including some cases of metabolic autointoxication." It seems to me that the Doctor has not made it quite clear just why, if the fast is the certain producer of the condition, he recommends it for the cure of the condition. Perhaps "similia similibus" or "the hair of the dog theory" is implanted in the Doctor's ego.
