The author reports on u series of eases of caisson disease. In the first of two series recorded there were 45 cases during 70,500 work hours ana in the second sorles, during which there was more stringent regulation of tho tine of decom pression, there were 33 cases in 152,000 work hours. This valuo is still quite high for well regulated diving operations :nc wa3 due possibly tc the fact that there w.s no safety apparatus which enforced longer decompression periods. 39 CUTANEOUS HOARDS IN THE FUR INDUSTRY. O.L. Lovin and H.T, Bohrman. Ind. Med. 7, 673-1 ('lovjmbor 1936). The he\lth hsasris in the fur industry together with a brief description of the processes one materials used r.ro presented. By far the most common hazard 1b dermatitis although- t;:or diseases that arc encountered ere anthrax, catarrh and isthtia. Thv. disc..300 r.rc caused by contact with the skins themselves, with tho acids and othj.- chor.icils usoi, 'Jid with tiio numerous synthetic and organic dyos. The action vf , Z>x t..:- substances is a purely chemical one butin many caaos it is en'.p.;ylictoid, '..hero the individual is allergic tc tho material. Prevention is best accomplished by personal cleanliness end by good sanitary measures with ing tho plant. 40 EUUN5 FRO.'.. aCETYLENE WELDING. J. Am, Med. Assod. (Queries and minor notes) 111. 469 (1938). a doctor writes that cany cases of bums from acotylono wolding become infected although immodiato treatment is provided. It is probably not the flux that causes tho infaction but more likely tha dust and small motal particles present on tr.c shin. For this reason very thorough cleansing of tho wound is neoessaiy. 41 LEAD IN THE PRINTING INDUSTRY. J.M, I.'epler, P.F. Resin snd R.ff. Colina. J.Ind. Hyg. 4 Toxicol. 20, 641-5 (December 1938). Evidences obtained in n preliminary survey of tho printing industry in Michigan, by the Bureau of Industrial Hygiene, indicated, contrary to contention, that sufficient load fumos wore presunt in tho air to constitute a hazard. They then made tests in 14 representative printing establishments to detormine the actual concentrations present. Most of the previous work on load in printing shops had bean dona boferu exact methods of load doterminntion were in uso and were thought to bo inaccurate in many coses. The results of the present tests indicate that the former contentions are entirely unfounded and that considerable lead fumes can be given off from the lead melting pota whan heated above the melting point even though the motal is not agitated. They found that lead fumes ore more im portant than lead dust and that the film of oxide on tho aurfacee of the melting pots had no appreciable effect an the concentrations of tho fumes. 42 HYGIENIC CONDITIONS IN BOOK PRINTING PLhNTS IN NaFLES. R. Tecce tad C. Beseoro. Folia nod. 117-33 (1938). (Italian). In an investigation of the hygienic conditions in 15 Neapolitan printing shops, measurements wore maae of the height and cubic content of rooms, dust concentra tion and' tt-nparnturo and humidity of the working spaces. The plants were divide- into gcud ones having 15.7-70.0 cubic motors per worker, 150-190 particles per c (Owens counter) 5.4-6.0 dry knta value and 14.7-17.2 wot) the inodium and poor plants hod 4.3-42.6 cu.m, per worker, 270-300 particles per cc. and dry and wot kata values of 4.0-4.7 and 12.3-15.8. Tho lighting was poor in most shops. Tho load content of deposited dust varied from 5.5 tc 16 per cent. Examination of workers skvwod 80 per cor.t to have lead lines and 23 per cent to havo stippled erythrocytes. HWB8-0009783
