[To THE EDITOU Or THE "SPECTATOR."] SIR,—In connexion with the letters of Mr. R. Walker Berry (Spectator, August 3rd) and Miss Anderson (Spectator, August 17th), may I quote a description of the pain suffered by my father, the late Dr. G. S. Keith, during a difficult opera- tion for the removal of a black cataract? He says : "The pain was different from any I have ever experienced. It was different entirely in kind from the slight pain of cutting the iris. At the moment the idea occurred to me that it was a blue pain, and that of cutting the iris, or skin, or any other muscular texture was a red pain " ("On Sanitary and Other Matters," page 62).—I am, Sir, ac., HELEN KEITH.
