In the editorial, "Pierre-François Rayer (1793-1867) Physician to the Kings of France" (191:856 [March 8] 1965), the second line in Reference 3 was incorrect. The complete reference should read as follows:
3. Rayer, P.: Treatise on Diseases of the Kidney, Z. Danilevicius, trans. (excerpt), Paris: J. B. Bailliére, 1840.
