Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from House-Flies and How They Spread Disease About eight years ago, on being asked for some information of a special kind regarding the house-fly, I was surprised to find after looking into the matter, that our knowledge of this insect was of the most meager character. Notwithstanding the fact that it is usually the first animal with which man makes his acquaintance on entering the world and is certainly his most constant companion through life, little attention has been paid to this the commonest of insects. A few studies of its life-history and development had been made in the United States and Germany but there was no accurate information concerning its structure, and the general ignorance of its biology and habits was astonishing, to say the least.
