1029. Dried specimens are kept in herbaria in various ways; sometimes loose between leaves of paper; at other times wholly gummed or glued to the leaves of a book; but most generally attached by one or more transverse slips of paper, glued on one end and pinned at the other, so that such specimens can readily be taken out, examined, and replaced. On account of the aptitude of the leaves and other parts of dried plants to drop off, many glue them entirely, and such seems to be the method adopted by Lin-nï¾µus, and recommended by Sir J. E. Smith. 'Dried specimens,' the latter observes, 'are best preserved by being fastened, with weak carpenter's glue, to paper, so that they may be turned over without damage. Thick and heavy stalks require the additional support of a few transverse strips of paper, to bind them more firmly down. A half sheet, of a convenient folio size, should be allotted to each species, and all the species of a genus may be placed in one or more whole sheets or folios. On the outside of the latter should be written the name of the genus, while the name of every species, with its place of growth, time of gathering, the finder's name, or any other concise piece of information, may be inscribed on its appropriate paper. This is the plan of the Linnï¾µan herbarium.' A very handsome gardener's herbarium has been formed by Mr. Toward, of Bagshot Park. It is in four thick folio volumes; the leaves are of cartridge-paper, and each has a leaf of brown blotting-paper pasted to its back. Bound the margin of the cartridge-paper side of the leaf are pasted strips of the same paper about half an inch broad. These strips rather more than compensate for the thickness of the dried specimens; so that when the leaves are bound up, their edges cut, and the book shut close, the external air is excluded, and the appearance is as neat as that of any printed volume.
