To the Editor:  —Dr. Coffey has repeatedly stated in the public press that he and Dr. Humber make no claim for a cure, yet in the United States patent number 1771976, signed by Walter B. Coffey and John D. Humber, there is the following opening statement: "Our invention relates to a therapeutic substance having the property of stabilizing tissue growth and which, by virtue of this property, is capable of controlling and/or destroying carcinoma, sarcoma and other malignancies." Obviously these two statements are contradictory.This patent claims that the Coffey-Humber extract is an adrenal cortex extract, stabilizing growth, and that it controls or destroys cancer. These claims may be easily proved untrue. First, there is no possibility of this water and alcohol cortex extract being an effective hormonal extract, as this method of preparation cannot produce an adrenal cortex extract which can substitute for the cortical hormone in adrenalectomized animals.
