Bui. 25, n. s. 1900) mosquitos, particularly Anopheles, might be obtained by provid- ing free ventilation in area ways and other sheltered places like porches, so that mosquitos would be disinclined to take refuge therein. As is well known, these insects may also be found in outbuildings of various kinds, in fact in almost any dry place where there is not too much air. They fly throughout the sum- mer and we have met with specimens on snow in the middle of March. The natural breeding places of Anopheles larvae, according to Dr Howard, are in the more or less permanent pools of water such as are found in the bed of an old canal in spring, in wood-.
