POISONS FOR SALE [To the Editor of THE SPECTATOR.] SIR,—Your

columns are not the most appropriate place in which to conduct a correspondence upon a technical subject. Nevertheless, may I be allowed to assure Dr. Roberts that two of the seven substances he mentions are in Part II, and not in Part I, of the Poisons Schedule ? This correction will be made in the next edition of the Extra PhitiMaeoPOcis, unless in the meantime the law is changed.—I am, Sir, &c., HUGH N. LINSTEAD, Secretary, Pharmaceutical Society of Great Britain, 17 Bloonisbury Square, London, W.C.1.
