P. Stocks. J. Boy Statistical Soc. 101. 669-96 (1938) (Bfrfc@h). Somo occupations have given the statistical impression of being intrinsically unhealthy, whereas thoir unfavorable mortality might arias from their particu lar localization, whereby tho workers and thoir families share tho highor deathrates which predominate in that locality. This faot may ba a factor in certain industries only carried on in larger cities, and, though well distributed ever the country, high mortality may ba due, not entirely to tho industry itself, but to the urban conditions. Cases ore cited in England, whore, if these facts ore overlooked, certain arroneous conclusions might bo drawn. Conclusions drawn from a sirvey of tho general population show that highor death ratoa can be cor related with highor latitudos, housing facilities and ratio of unskilled work ers. A retlor of tho standardized mortality of males to that of married women has bson used to lndloate whether a .high mortality among employed man represents a true occupational risk or is one inherent in the enriroaunt. References to Recent Literature - 4 96 Zm&'EnfTH ANNUAL REPORT 07 THE INDUSTRIAL RESEARCH BOARD TO JUNE 30, 1936.

Accidents occur at a specific moment, in point of time, but this is not true of most occupational diseases, and it makes difficult the fixing of liability. Another problem is in the taxes of coverage as prescribed by law. Same states have "all inclusive" statutos which make the coverage indefinite and impossible to keep within the bounds original ly Intended. No new legislation of this type has beta onactsd within the past throe yoars. The trend has been towards specific schedules of compensable dis eases, which limit the liability of the employer, reduco litigation, and oaks the administration much simpler. A brief description is given of the "graduat ed" method of compensation of silicosis casss which have accrued in the post, but which have only recently bean made compensable.

It is also believed by many per sons that all atmospheric durts may be harmful if brmathsd in large quantities fo long periods of time. For tnose reasons the authors stress the importance of duat control in coal mines. This paper enmarntos the principal sourcos of lust and describes practical oothoda of employing water as ons of the meet effective of the known methods to allay duat in coal mines. Most dust in mined originates at tha face and the amount of water necessary* if applied efficiently, is aot excessive.

Dudley. U.S. Pub. Health Repair, 54/^43, (Jon. 13, 1939). Kraft paper is the brown paper used in rotoll stores fO^rtapping pnekages; heavier grades are used in shipping carton and eeutalnars. The authors outline the method used in evaluating tho odor nuisance generated in the manufacture of this typo of paper by the sodlim sulfide - sodium hydroxide process. Tho odors cf hydrogen sulfide, organic sulfur compounds, corbon^gditap and a chemical smoke containing large quantities of sodium sulfate ana^tadlum sulfide are given off during nearly all processos and pass out through the%p4*ks to be classed as a nuisance In the neighborhood. The htmon nose is rcmarfittdy sensitive to minute traces of these substances in tho atmosphere, even iif those concentra tions that are wall below tho toxic limit. It is concluded that In the neigh borhood of the plants the concentrations of toxic gases are of no consequence. The major contributing factor in the obnoxious conditions is due to the large amounts of solid chemical materials, mostly sodl\a sulfate, which are blown out through tho stocks oad soon settlo to the ground. Tho possibility of electrical precipitation for prevention and economical recovery is stressed. References to Recent Literature - 11 127 THE DANSERS OF ARC WILDING. H. Pozzi.
