Abstract
AS recorded in NATURE of. December 17, 1914 (vol. xciv., p. 433), Sheffield is one of the cities joining in the observations on atmospheric pollution Abatement Societies of the United Kingdom, monthly results of the chemical exai water collected at four sites, appro E., and W. of the Town Hall,2 hav in the Lancet, and are being embodi report of the medical officer of heal Sheffield. The results do not accord and certain conclusions have been reached which are perhaps of more than local interest, as they throw doubt on the value of chemical analyses of rain-water, either in the investigation of atmospheric pollution or in a comparison of the extent of pollution in different localities. It should be borne in mind that in Sheffield the distinction between factory and domestic smoke, which is based on the relative amounts of tarry matter and ammonia in the atmosphere (this journal, loc. cit.), cannot be drawn owing to the large number of reheating and annealing furnaces in operation in the east end (where the large steel works are situated), for which coal is burned so as to produce the smoke necessary for the metallurgical processes involved.
