The Life-History and Anatomy of Butterflies efficient in the case of many of the small species when they are still fresh; in the case of the larger species the scales may be re- moved by means of a camels-hair pencil such as is used by paint- ers. The chemical method of bleaching wings is simple and inex- pensive. For this purpose the wing should be dipped in alcohol and then placed in a vessel containing a bleaching solution of some sort. The best agent is a solution of chloride of lime. After the color has been removed from the wing by the action of the chloride it shoyld be washed in a weak solution of hydrochloric acid. It may then be cleansed in pure water and mounted upon a piece of glass, as microscopic slides are mounted, and thus pre- served. When thus bleached the wing is capable of being mi- nutely studied, and all points of its anatomy are brought clearly into view. The veins in both the fore and hind wings of butterflies may be divided into simple and compound veins. In the fore wing the simple veins are the costal, the radial, and the subme- dian; in the hind wing, the cos- tal, the subcostal, the upper and lower radial, the submedian, and the internal are simple.
