Excerpt from A Handbook of Hygiene: And Sanitary Science I very much regret that this Handbook has been out of print for more than a year. While the delay in preparing a new edition has been much interfered with by official duties, it has been mainly due to my earnest endeavour to render the work still more worthy of the very favour able reception which has been accorded to it ever since it was first published. With the exception of a few chapters, all of which have been carefully revised and brought up to date, the whole of the book has been re-written and in spite of every effort to compress, the present edition has been enlarged to the extent of more than two hundred pages, and contains a considerable number of new wood-cuts to illustrate more clearly those portions of the text which apply to ventilation, sanitary fittings and drainage, house building, isolation hospitals, and parasitic diseases.
