During the past six years I have devoted considerable time to the study of specific cancer therapy, and various phases of these investigations have been published from time to time as definite facts of scientific interest were obtained. The work is based on the theory1 first published in 1910, which states that through altered chemical nature the normal tissue-cell changes into the malignant cell.
