THE letter from Messrs. F. K. Jackson and R. L. M. Ghose1 on the protection of herbarium specimens makes a valuable suggestion. Perhaps I may be permitted to refer readers and others interested in the subject to a paper on the “Preservation of Herbarium Specimens and Insects on Celluloid”, by Mr. John Ritchie, of the Perth Museum, published in the Museums Journal for May 1930. If Mr. Ritchie's method of mounting on a transparent sheet of celluloid were combined with the cellophane covering employed by your correspondents, the plant would not only be protected, but would also be visible from both sides.
