Insects dropped into it will be killed in fromtwo or three to ten minutes. Keep a little tissue paper inthe bottle to soak up moisture and to prevent the specimensfrom rubbing. Also keep the bottle well corked. Labelit Poison, and do not breathe the fumes (hydrocyanic gas).Insects may be left in it over night without injury to them. Butterflies or dragon-flies too large to drop into the kill-ing-bottle may be killed by dropping a little chloroform orbenzine on a piece of cotton, to be placed in a tight box withthem
