ABSTRACT THE eighteenth report of the Department of Scientific and Industrial Research on the “Investigation of Atmospheric Pollution”(H.M. Stationery Office, 5_s_. net) records observations

for the year ending March 31, 1932. It shows that the co-operation of local authorities has been well maintained in spite of the financial difficulties of the times. Comparisons between

towns on the basis of the tests, should, it is stated, be made with caution. A deposit gauge may be placed in a position where conditions are not truly representative, and it is the trend of

the results over a period rather than the absolute weights of deposit which should be stressed. From this point of view there is evidence of improvement in the atmosphere of some provincial

towns of Great Britain. This cannot be said of the deposit of tarry matter, which is “pre-eminently a product of domestic fires and there is little reason to think that the amount of smoke

from domestic fires has decreased much in recent years”. Deposits of sulphate have increased in some places, notably Ravenscourt Park, London. Such increase, it may be inferred, may be due

to the increase in the sulphur content of the fuels burnt—some fuel oils are rich in sulphur—or to the concentration of fuel burning on one site, such as in large power stations. London does

not show up well in the matter of smoke fog while Coventry again has an excellent record, ascribed last year to the use of gas for domestic and industrial heating. Access through your
