This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1869 edition. Excerpt: ...though varying somewhat to meet the exigencies of the case. These giants of marine vegetation are far too large--they often extend to a distance of eleven or twelve feet--to allow of their being dried and pressed in the ordinary manner; while at the same time the specimens lose a great deal of their interest and attractiveness if their fair proportions are too closely shorn. It is necessary, then, to select a middling-sized example for preservation; but even a middling-sized example will need a press far beyond the iisual limits. Fortunately, the student has no need to dread a failure, so far as his materials are concerned. He has only to cover the floor of a room pretty thickly with sheets of blotting paper--the covered space measuring about six feet by three--and then to lay over this the Laminaria, which must be so far dried beforehand as to have lost the slimy feeling which it usually communicates in the growing state. More sheets of blotting paper being spread over the Algse, the whole is to be covered with a smooth board of corresponding size (or in default of one so large, with several smaller boards), upon which a sufficient quantity of bricks should rest. If, after all the pains taken, the specimen is found to be too long for any reasonably sized press, the lower end of the frond may be turned over, not immediately upon the body of the plant, but at an oblique angle--blotting paper being laid inside the joint, so as to keep the parts from actually touching each other, where it is impossible to prevent them from coming together. The papers should be frequently changed, as the thick leathery substance of the frond makes the process of drying somewhat dilatory. However, the business of changing the layers of paper is rendered less...
