This might be a good warning to chemists ar.d those who work with irritant substances to have yearly roentgen oxaninatione of the chest. 65 INJURIES TO HEALTH CAUSED BY nLUMINUM AND PARTICULARLY THE EFFECT OF .XUMINUM DUST ON THE LUNGS. M. Doese. Arch. Gowerbepath. u. Gowerbehyg. 1, 501-30 (1938). (Gorman). In an investigation to decide whether aluminum dust caused a characteristic dis ease of the lungs, data was collected fron examinations of 86 aluminum smelter workers. It was found that silicosis did not occur among the men, which agreed with too British investigations. It was found, however, that there wa3 damage to the upper respiratory tract in the form of catarrh, irritation or atrophy of tho nasal mucus membrane and perforation of the septum, Whother these wero due to the aluminum specifically or to a general effect of dust was not concluded because of the small number examined. The comparative hamleBanoss of aluminum in the stages of production is in narked contrast to tho dangers of spraying with aluminum paint, as in the latter case it seems there is a noticeable offoct on the lunge which is regarded as specific. THALLIUM POISONING. F. Kunkele. Chen. Ztg. J5g, 49-61 (1938). (German). The author gives a short history of thallium poisoning and descrlbos the detec tion r.nd determination of tho substance in parts cf the body at autopsy. He re ports on k cases of death from thallium which he had examined. 67 FLUORINE POISONING. J. An, Med, Assoo, (Queries and minor notes) 111. 273 (1938/ Pulmonary edema is the outstanding characteristic of acute fluorine poisoning and as little as 0.2 mg. per kilogram of body weight may cause trouble when in hale:'. In chronic cases overgrowth of bone, caloificatlon of ligaments and bone fragility are comnon, but tend to disappear when exposure is stopped. In acute cases, oxygen inhalation, bronchial sedatives and ontispasmcdics, and intravcnou calcium gluconate ore suggested. Ton roforences are cited. 68 A PORTABLE INSTRUMENT FOR THE ANALYSIS OF HYDROCYANIC ACID 0AS-AIR MIXTURES. R.J. Viilmot and T.N, Gautier. J. Agr. Rest-arch , 283-90 (1958), n instrument is described which analyzes hydrogen oyAnicle gas-air mixtures by physical apparatus. The sample Is drawn, by means of a small motor driven pump contained in the instrument, ovor a hot platinum filament. The change in resis tance of the filament is then measured by means of a Wheatstone bridge and is translatei into percentage of hydrogen cyanide by volume. It is accurate to within 0.02 per cent. 69 PRINTERS* SPRAY AND METHYL ALCOHOL. J,Am.Med.Assoc, (Queries and minor notes) 111. 85 (1938). A spray used widely in printing contains methyl alcohol, gum arable and gum tragaaanth. Or.e printer is known tc have developed asthma which was traced to the gum antic and which was ovorcome by substituting starch. Most of the com plaints concerned not the spray but the dust loft when the alcohol evaporates. Exhaust ventilation may be suggested and mothyl alcohol should not be used. 70 EFFECT OF GULrUFv CHLORIDES ON EYES, J. An.Mod. assoc. (Queries and minor notes) 111. 1492 (1956). Sulfur chloride is thought to be non-toxic by Hamilton and Lehmann. Since It is frequently used along with carbon disulfide, any injury is thought to be caused by the latter substance. Kober and Hayhurst consider toe decomposition products to bo harmful and Adler-Horzmark has reported general poisoning by sulfur-mono chloride in the absence of carbon disulfide. Injury to the eye would probably Be accompanied by other, moro characteristic, injuries. HMB8-6009788
