An appeal from diabetics and the Diabetic Association that thero was u prejudice against then by employers because of their diabetes led the authors to believe that this prejudice was unfair, ur.Just and a survival of the pre-insulin period, =ind they beg3n a survey of the tine-lost record of diabetic patients. Their re port covers the rocord of 100 employed diabetics, selected at random, who wore taking regular insulin treatments. The number interviewed wa3 too small to draw definite conclusions, but the authors form the opinion that most troated diabetic, are good employees from the health point of viow, and hope that the widespread --U prejudice against their employment may be removed, 78 AIR JET VENTILATION IN HOT WEATHER. T.C. .e'.gas. Heat. & Vent. Eng. 1, 2-5 (July 195e), (British). The Jot fan consists of small centrifugal far. (1/2 h.p. to 1-3/4 h.p.) deliver ing through n jet tube sc ub to discharge a horizontal, flat, wide stroam just above head level. Although the main air current passes overhead, the high velo city (up to 4000 f.p.m. at the jet) induces secondary air currents, and the re sult ic that in the neighborhood influenced by the Jot fun, air currents are var iable instead of mrnotor.nus, and thus are more refreshing. Air velocities as high as 160 f.p.n. have boon roccrded at shoulder level 60 ft. or so from the jot. In shops where hot processes are carried on, or in hot weather, such air nevemimt is most welcome. Jet faus have been used to dissipate local clouds of disagreeable fumes or Vapwra to reduce their concentrations to negligible levels. They will not solve ell summer factory ventilation problems, but along with good natural or simple oxhaust ventilation they will form a useful and cheap auxiliary 79 METnBOLIS!. OF MAN ,iT WORK UNDER DIFFERENT CLIMATIC CONDITIONS. 0. Ehrisnann. Ztschr. f. Hyg. u. Infektionskr. 120. 319-40 (1958). (German). At higher temperatures and humidities the increase in metabolism accompanying work is approximately the same as under ordinary conditions. The recovery time may be delayed and in somo cases the respiratory quotient is lowered. The body weight may increase in spite of the less favorable conditions. No evidenco was forthcoming that nitrogenous metabolism is disturbed when work is done in envir onments of lower cooling power, 80 HEaT REGULATION AND MUSCULjlR WORK. W. Liber3on. Trav. humain , 41-51 (1938). (French). The author discusses the effect of temperatures on the energy yield of muscular work, about which thore aro various views. He 3tates that the energy yield re mains practically constant in temperatures between 9-40C, but the technical yield (mochanical efficiency) of work rises with a decrease in temperature, at least between 9-45C, 81 I HE INFLUENCE OF CLOTHING ON THE PHYSIOLOGICAL REACTIONS OF THE HUUaN BODY TO VARYING ENVIRONMENTS TEMPERATURES. A.P. Gaggo, C.E.A. Winslow and L.P. Herring ton. An, J. Physiol, 124. 30-60 (Octobor 1938). The partition of hoot loss from a normally cbthed subject shows that ho is ablo to tolerate a Jifforence of 8C botweon skin and environmental temperatures be fore cooling sets in at 25C (as compared with 29C for the. nude subject.) Botween 25C and 29C, thermal equilibrium of the- clothod body is maintained by vasomotor regulation. Above 29C evaporation regulation soto in. It was shown, by plotting various physiological factors against caloric demand, that the groan physiological responses cf the body are about the same nude as when clothed ex cept fer tho temperature at which the response takes place.
