Abstract

positive result. The patient had been given sodium iodide, and the urine also showed lead. Of 12 other cases of various conditions, in only one, a case of lead initoxication, were abundant crystals found in the cerebrospinal fluid. In this case there was 0-2 mg. of lead per litre of urine. Taking all three studies into consideration, there is no adequate proof for, and ample evidence against, the theory that lead is an aetiological agent in cases of multiple sclerosis. R. M. S.
