Protection of Herbarium Specimens

Abstract

IN making a herbarium collection of Indian types of cotton, the necessity was felt of protecting the mounted specimens from injury while handling. To meet this difficulty, the senior writer suggested using a transparent celluloid material as a covering for the specimens. ‘Cellophane’, ‘Cellglass’, ‘Sidac’, and other trade names are applied to such products, which are sold in sheets, and are very thin, tough, flexible, transparent, damp-proof, and inexpensive. In commerce, these materials are used for wrapping boxes of chocolates, etc.
