Work against mosquitoes is being undertaken everywhere, by individuals and by communities. The interest in the subject, from both medical and lay points of view, has become so great that persons are not satisfied with half knowledge, but must know the whole mosquito story, and it has been with the purpose of supplying in some part this demand for information, that this book has been prepared. It tells what is known about mosquitoes from the biological point of view, from the medical point of view, and from the practical side. An especial effort has been made to show, in a straightforward way, to physicians how the different kinds of mosquitoes can be distinguished, and to indicate the characteristic habits and breeding places of those forms which spread malaria and yellow fever. -- Introduction.
