Society for bettering the condition of the poor. [electronic resource] : The following Rules to prevent Infectious Fevers, have been extracted from a manuscript of Dr. Haygarth's, with his permission. They are intended to enable medical and clerical visitors of the sick to perform their important duties with safety to themselves, and are printed by the Society with a view to their being distributed, so that a printed copy may be put up in every house where there is an infectious fever.
