Through his work at Mellon Institute for two decades, Dr. Meller became^ internationally as a specialist on air pollution.

H. Kliewe. Ztschr. f. Hyg. u. Infektionskr., 7-733 (May, 194217" (German) , 'Cultures of five species of .non-sporing and two of sporogenous bacteria were dried on filter-paper, and these were placed in linen bags which were distribut ed among packages of clothing in a hot air sterilizer- Cultivation of those test objects after the maintenance of different temperatures for various periods show ed that in order to be sure of destroying non-sporing bacteria it is advisable to use a temperature of 100-110C, for hours; the temperature necessary for destroying spores (130C. sufficed for those tested) is such as would damage fabrics. Hot air sterilization is therefore unsuitable for clothing if total disinfection is required, but the usual object is to destroy the agents of infec tious diseases, which are non-sporing bacteria and viruses. As might be expected disontinuous hoating for short periods on successive days was no more effective than continuous heating for the same total period. Heat and Ventilation in Air Raid Shelters. W'.J. McGuinness. Heat., Pip., & Air Cond., 15, 193-196 (April, 1943). This article gives the requirements for heating and ventilating air raid shelters. The various types of bombproof and splinterproof shelters are shown. The bomb proof typo is too expensive to construct, hence the most common type is the splinterproof. Shelter size is fixed by number of occupants. No more than 50 people should be placed in the same room. Space and volume requirements for overground and underground shelters are given in a table. Heat requirements are low because of the number of occupants, however, heat losses in England are different from ours because of climatic conditions. On this basis an underground shelter is preferable for American climatic conditions because of the lower ground temperatures which aid in heat loss maintenance. Ventilation require ments arc given and the various types of systems employed are illustrated. Mechanical systems with filtration are recommended. Wartime Operations Emphasize Industrial Hygiene Problems of Asbestos Industry. Illinois Labor Bull., 3, 10, 11, 22 (February 28, 1943). The control of asbestosis must be an engineering control because there are no medical means to detect the disease until much ham has been done. Engineering control consists of two important principles: (1) Adequate exhaust, (2) Good housekeeping. By experiment it has been estimated that if the air contains loss than 5,000,000 particles of asbestos per cubic foot there is small chance of the workers developing asbestosis. The article lists the procedures in the manufac ture of rigid and of textile asbestos products and shows that further protective measures are still needed in most plants. Industrial Medical Practice Industrial Health - Its War and Postwar Significance. C.O. Sappington. Ind. Mod., 12 , 361-364 (June, 1943). The paper considers war and post war problems of industrial health, which are classified into those of medical administration, those of public health in indus try and in the community and those relating to industrial hygiene and sanitation in the plant. Brief but rather comprehensive discussions of the following prob lems are presonted: Venereal disease control; Nutrition; Immunisation; Proplaconent and periodic examinations; Women in Industry; Dermatoses; Absenteeism;
