The Middlesex Hospital has for some years led opinion and

practice in the treatment of cancer. A new and most promising result of technical research carried on in the laboratories in connexion with radium was des- cribed last week by the Chairman of the Court of Gover- nors, Mr. S. A. Courtauld. The wastage of the precious substance by slow disintegration into the atmosphere has been cured or greatly reduced. The emanations in the form of gas, called radon, are condensed into solid " seeds " and saved in tiny tubes. Each seed is capable of doing the wonderful healing work of the parent radium. Seeds have been used at St. Bartholomew's already. and the Middlesex proposes to offer them to other hospitals. The capture of these formerly lost emanations gives hope for an extension of beneficent effects which would other- wise have been impossible.
