- 7 - Boric acid occurs naturally in the water and jets of steam which issue from the ground in Tuscany, and impregnates the air of the factories, Sir W. Pope writes that operatives in the factories '"excrete eight grains of boric acid a day, and the death rate is less than the average for Italy.” Professor Glaister reports in the Morning Post, March 2nd, 1925, that examination of operatives in British boric factories showed that many years exposure to the boric impregnated atmosphere is without deleterious effect. In the face of so much difference of opinion between experts the need for a comprehensive research becomes obvious. One realises that it is very difficult to get conclusive results with substances of such low toxity as boric compounds. Until such a research is done it is desirable to ascertain what is the International consensus of opinion. Presumably no body sufficiently representative has yet presented an opinion. The most representative opinion is probably that of the International Union of Pure and Applied Chemistry. It was agreed at Copenhagen in 1924 by representatives of 15 countries that the evidence was inadequate to justify the statement that boric compounds exert a cumulative effect on the body. If we agree with Professor Dixon, and take the position that "any substance which is known as a poison must be assumed to be injurious to health, even when taken in the smallest doses, unless there are definite and specific reasons for believing the contrary, then we ought to consider the prohibition of the use of chemical substances in other directions, for example, the purifying of water by powerful chemical substances, chlorine or hypochlorites, as practised by the London Water Companies, and others, and again, the addition, of sodium silicate to certain water supplies
