Including rate o( industrial waste emission, stack density and ejection speed, and plant configuration, including stacks. The effects o( Inver, slon, cumulative effects, and wind speed effects are discussed. Scale model wind tunnel experiments have been most sueccss(ul in the study o( air pollution (rem short stacks, a (leld in which analysis o( concentration characteristics by theoretical or empirical methods is difficult, la the second paper the New York University wind tunnel is described, including photographic apparatus and other methods o( light measurement. Results obtained so (ar have not reached the stage o( usefulness (or routine investigations o( air pollution problems, but a closer approach has been made to the understanding of the problems o( individual plants and o( groups o( plants. The series will be continued. 289 Some Observations on London Fog. R. E. Waller and P. J. Lawther. Brit. Med. J. 2. 1256-1358 (Dec. 3, 1955). Visibility may be greatly reduced in London by smoke, in the absence of (og. On January 19, 1955, very wide variations in the concentrations of smoke were observed, and a tenfold increase occurred over a period of two hours. There was also an Increase in sulfur dioxide, but no sulfuric acid was detected by the methods used, although traces might have been present in the form of minute droplets. A temporary deterioration in the clinical condition of some patients with chronic bronchitis and emphysema coincided with this episode. The results emphasize that measurements of pollution over 24- or 48-hour periods do not necessarily indicate the hazard to which the population may be exposed. -- Authors' summary MANAGEMENT ASPECTS 290 Executive Health: Fourteen Ways to Maintain It. L J. A. Villaloo. Research fc Eng. 2, 34-36 (Jao.1956). The following hints are given to the busy executive from leading doctors and psychologists on how to keep healthy without impairing drive and efficiency: (1) don't be afraid of finding something wrong with yourself; (2) don't neglect the annual physical exsminatlon; (3) don't let the job boas you; (4) get rid of health problems; (S) know your own limitations; (6) save yourself (Or the important things; and (7) most important of all, learn to relax. Seven sane ways to relax are: (1) change your pace; (2) plan and organize; (3) pUy to relax: (4) use your imagination; (5) talk to relax; (6) do (or others; and (7) laugh to relax. Each of these hints is discussed. 291 Industrial Sanitation and the Worker's Health. J. L. Barron. Modern Sanit. 8, 13-15, 48 (Jan. 1950). The author pleads (or more attention to industrial sanitation. A balance of sanita tion, safsty, and industrial hygiene yields a compute protection program. A sanitation pro gram includes: (1) daily maintaaaaca of personnel facilities; (2) cleaning and periodic refiniahing of surfaces; (3) cleaning of machines sad equipment used in manufacture; (4) protection of materials; (S) control of pests and prevention of bacteria and mold contamination; (6) coUecUon, salvage, and disposal of refuse; (7) checking of water supply and water-boms wsste dis posal facilities; (8) operation of uniform, laundry and sanitation stock room services; (9) maintenance of exterior groands; end (10) plant guarding and supervision of watchmen. Where occupation hazards exist, the Inspection and surveillance may require extensive work by in dustrial hygienists and safety engineers to discover snd svalnate the hazard, and periodical Inspections to vsrify thd^ffrttt of corrsctivs msssnrss. Thsss special services, distinct from the day-to-day sanitary maintenance of the work environment, are, however, comple mentary and interdependent.'
