The Asbestos Industry, being comparatively young, plays but a modest part in the Nation's activities as a whole. That would appear to be the only excuse for the even more modest position which it holds in the literature of Medicine. It is from the clinical aspect that I have perforce studied the effects of this industry on those employed in it, for it is in the course of General Practice alone that I have access to the subject. My attention once aroused by the frequent occurrence of intractable pulmonary disease amongst my patients working in a local asbestos factory, I soon found that not only do the workers regard their occupation as almost inevitably productive of Phthisis in the long run, but that the employers are so wide awake to the risks as to establish and enforce precautionary measures on a scale far beyond the requirements of the Factory and Work Shops Act. If I have been afforded some opportunity of observing the conditions under which my patients are employed, it has been entirely due to the courtesy and enthusiasm of the management at Leeds. I have no official status.
