The Chemical and Toxicological ComJmittee is planning an informal discussion type of meeting. Some of the early ^ ^^suggestions of topics include the effects of gases occurring in industrial plants .as a result of explosions and fires, labelling requirements for chemical mater-, ials, and compilation of a new trade-name index. These subjects are tentative. Further suggestions from Member Companies will be welcome. The Medical Committee, Legal Committee and Engineering Committee would also be pleased to Consider any suggestions offered by Members as topics for discussion ; at the respective Conferences. This is your meeting, and we would like to have your views on subjects you believe would be of value and interest to you.

Med. deport y trabajo lb, 4788-4802, (Mar. 1952) English Section. The author presents a general review of silicosis, including etiology, pathogenesis, diagnosis, prognosis, and treatment. He then discusses the effects of mixed siliceous dusts and minerals, especially graphite, earthenware, and granite. Asbestosis, other fibrous silicate minerals, and non-fibrous silicate minerals are considered briefly. The effects of non-siliceous dusts, especially beryllium, and of vegetable dusts, are reviewed. 79 History of Lung Diseases of Coal Miners in Great Britain: Part II, 1875-1920. A. MHklejohn. Brit. J.Ind. Med. 9, 93-98 (April 1952). The author continues the review of the history of miners' pneu moconiosis (see IHF Abst. 1136, Oct. 1951). The principal developments in the period 1875-1920 were: the extension of interest in occupational diseases in other industries than mining: the development of workmen's compensation laws; and especially the gradual realization that free silica is an important factor in pneumoconiosis of miners. 80 Pneumoconiosis of Coal Miners in North East England with Special Reference to the Durham Coalfield. R. I. McCallum. Brit. J. Ind. Med. h 99-107 (April 1952). The extensive occurrence of pneumoconiosis late in the nineteenth century was reduced very greatly by improvements in ventilation at about the end cf the century. Mechanized mining has probably increased the rue prevalence of pneumoconiosis, but diagnosis has also improved. Evidence from routine mass miniature radiography at eight Durham pits suggests that a minimum of 3 to 6% of men in those pits show well-markec pneumoconiosis. Future developments in the coalfield will tend to intensify dust production and the risks of pneumoconiosis unless dust suppression methods are considerably extended. -- Cond. from Author's Summary
