Health of Factory Inmates. THE health of factory people was made the theme of medical mystification by Mr. Sadler, in dialogues which may furnish another comic scene to the Malade lmaginaire of Moliere. Several of the celebrated practitioners of London were summoned by him to expound to the Committee, hypothetical dogmas about the generation of disease under the circumstances of cotton-mill labour-a matter which they had never seen nor studied : and they displayed, of course, in their evidence, amusing specimens of the plasticity of the medical mind. I shall leave it to the ingenious author of Paul Pry, or the Comic Annual, to dramatize the details of the discovery then gravely recorded by the Faculty, " that great fatigue of body and mind, with want of food, air, and sleep, are detrimental to human health," and content myself with noticing their more specific conclusions as to the kind of disease which ought to result from factory employment.
