In the paper by Killian and Kast on "A Study of Significant Chemical Changes in the Blood Coincident with Malignant Tumors" in the Archives of Internal Medicine, December, 1921, the statement is made, page 813, that "the comparative decrease in the amounts of these (nonprotein nitrogen compounds) has been ascribed to an increased need for nitrogen for the new growth, whether it be malignant tumor or embryo." This statement follows a reference to the work of Theis and Stone, so that many would infer that the above explanation of the low nitrogen figures was offered by these writers. It should be stated that Theis and Stone offered no such explanation of the figures in this connection, but that the explanation was advanced by several workers verbally to us, and we inadvertently included it in our paper without proper explanation.

John A. Killian and Ludwig Kast.
