In the paper on Progressive Pseudohypertrophic Muscular Dystrophy by Dr. Garry DeN. Hough, Jr., published in The Journal for October 1931 (Vol. XIII, page 825), an error was made in the dosage of adrenalin. The sentence beginning at the bottom of page 835 should read: "Their method of treatment consisted of the subcutaneous injection of two-tenths to three-tenths cubic centimeters of a one-tenth per cent. solution of adrenalin and one-tenth to two-tenths cubic centimeters of a one per cent. solution of pilocarpin hydrochiorid, given daily or every second day up to fifty or sixty doses without interruption."
