At the present time, Whatman’s papers (so called) are manufactured at two mills, totally distinct, both of which are still worked by the descendants of Mr. Whatman’s successors; the paper in the one case being readily distinguished by the water-mark, “J. Whatman, Turkey Mill,” and in the other, by the water-mark simply “J. Whatman,” but bearing upon the upper wrapper of each ream the original and well-known stamp, containing the initials L. V. G., which are those of L. V. Gerrevink, as celebrated a Dutch manufacturer prior to Mr. Whatman’s improvements, as Mr. Whatman’s name has since become in all parts of the world. In making so marked an allusion to this particular manufacture, I am bound, perhaps, to qualify it in some measure by directing attention to the comparatively recent application of continuous or rotatory motion which has, indeed, effected no more wonderful or extraordinary results than in the singular conversion of pulp into paper. The largest paper now made by hand, which is termed Antiquarian, measures 53 inches by 31, and so great is the weight of liquid pulp employed in the formation of a single sheet, that no fewer than nine men are required, besides additional assistance in raising the mould out of the vat by means of pulleys; while by the aid of the _paper machine_, the most perfect production may be ensured, of a continuous length, and eight feet wide, without any positive necessity for personal superintendence. The principle of paper making by machinery is simply this, instead of employing moulds and felts of limited dimensions, as was originally the practice, the peculiar merit of the invention consists in the adaptation of an endless wire-gauze to receive the paper pulp, and again an endless felt, to which in progress the paper is transferred; and thus by a marvellously delicate adjustment, while the wire at one end receives but a constant flow of liquid pulp, in the course of two or three minutes we may have, carefully wound on a roller at the other extremity, the most beautiful and serviceable of fabrics. Instead of counting sheets in course of production as formerly, or even measuring the length by yards, we may actually have the paper drawn out as it were, and wound up, miles in length. In the recent Dublin Exhibition, a sheet was exhibited which was said to have been of sufficient length to wrap round the world; but, I must confess, that I am not in a position to vouch for the accuracy of the statement. An anecdote, however, is told, (the truth of which I have no reason to doubt,) of the patentee of this machine, and a relative or friend of his, of some considerable standing and influence in the pottery district, who were dining together about the period at which this machine was first adopted; when the one speaking of the advantages which he conceived the new mode would prove to his friend, alluded above all others to the remarkable capability which
