To the Editor:

It has been pointed out to me that there is a sentence in the paper of mine in the April issue of the ARCHIVES (Blank, I. H., and Dawes, R. K.: A.M.A. ARCH. DERMAT. 81:565, 1960) which is wrong scientifically. This is the last complete sentence on page 565. It reads, "Since the net negative charge on protein increases on the acid side of its isoelectrical point, one might expect combination with aluminum to increase as the pH decreases." This sentence should read as follows:
