Dr. to mere provincial technology were dispelled by the opening paper by Professor HAROLD UREY, professor of chemistry-at-large in the University of California; who, under the deceptively innocent title "The Dynamic Nature of the Atmosphere," told us of the formation and fate of the atmospheres of most of the planets including the Earth. Dr. L. P. I-]ERRndOTON, of Yale, displayed some of his laboratory findings on human reaction to experimental climatic stresses, and discussed the possible physiological mechanisms of acclimatization. The strictly limited atmo- spheres of nuclear-powered submarines and space ships of the future were discussed by Captain ALBERT BEtmxp., re nr ^•s ti- formerly director of the United States Navy Radiation " " Capsule Climates.

This might be air pollution which could exert its effect either directly by virtue of its carcinogenic nature or less directly by producing an antecedent and :: predisposing cbronic bronchitis. The panel discussion which followed this session was the only one of three to go with at~ any sense of reality and purpose, and one felt that open questions from the audience would have produced more fruitful discussion in other sessions. ~:.

Hydrocarbons from "Blow By" ; Professor TIAEoDORt: HATCU, of Pittsburgh, whose work and wisdom arc so well known in Britain, spoke of the classic concepts of the fate of inhaled dusts, and emphasized the need for further study of the pathways ofl lung clearance. Dr. T. F. MANCUso (Columhus), pleaded for more attention to be given to the additive effects--of minute amounts of pollutants of industrial' and communal environments. He was followed by Professor Emeritus R. R. NEwELL, who spoke with a fine sense of proportion on the airborne hazards of atomic energy. His paper ranged from the safety of reactors to the use of nuclear explosives in making a second Panama Canal. Dr. RtetanRD PRINDLE, of the U.S. Public Health Service, delivered a thoughtful assessment of modem "smog disasters," and Dr. LESLtE CHAMBERS demonstrated the monstrous role played by 3m, motor-cars in making Los Angeles a most irritant city; not only must the exhausts of cars be studied and suppressed, but Dr. Chambers told us of a new source of hydrocarbons in " blow by "-the loss of petrol through crank-case vents. The rival merits of the horse as a means of transport were discussed. Dr. PATRtcg LAwTtu?R, of the M.R.C. Group for Research on Atmospheric Pollution, distinguished British urban pollution from more exotic miasmata, and was followed by Professor T. J. KENr, who spoke humbly of the failure of the San Francisco Bay Authorities to plan effectively to limit pollution of their enviable air.
