DUST HAZARDS AND THEIR EFFECTS
P neomonoconiosis Caused by Asbestos D ust. London Letter, Jour. Am. Med. Assn., July 23,1927, vol. 89, p.804.
A t a conference of the Royal M i croscopical Society, held a t Liverpool, a case of pneumonokoniosis due to asbestos dust was reported by Dr. W. E. Cooke and Mr. C. F. Hill. I t appears to be only the second reported in this country. The particles found in the lungs were large, some measur ing as much as 360 microns. They represented the brittle iron containing p a rt of the asbestos fibers. The dust c o n t a in e d 18 p e r c e n t , o f i r o n a s f e r r o u s oxide, the raw m aterial 2.1 per cent.,
