The morning flight is shorter in duration than the evening one, is marked with greater precision than the evening one and takes place higher above the ground than during the The important facts obtained during this extensive experi- ment were: 1, the finding of blood in mosquitos of the return flight; 2, finding of males in the return flight; and 3, the definite mechanical adjustment to light intensity. More such experi- ments as these of Mr. Le Prince are needed; they yield more useful data than a lot of learned speculations over a few ideas. II. Observations from Boats: While mosquitos were being trapped at the swamp, two inspectors in a small row boat moved up and down the old French Canal, and by lying on the bottom so as to have the sky for a background, one of the men would observe the mosquitos as they flew past. This method was the first used to learn that a flight actually was taking Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of America.
