Its superintendence to completion was entrusted to the late Mr. Papworth, architect, who adopted as his model the monument erected at Rome to Scipio Barbatius, and faithfully imitated its classic outline and details. The Association in this instance likewise paid the expenses of bringing over Curran's remains from Paddington, and the erection of the monument was raised by voluntary subscription. Amongst the remarkable persons whose remains repose here likewise

we may mention the names of Mr. Ruthven, late M.P. for Dublin, to whom a monument was erected by subscription; Tom Steele, the fides Achates of O'Connell; Sir Simon Bradstreet, and John O'Connell.

Monuments of an important class distinguish the family vaults of Sir Timothy O'Brien, Chief Justice Monahan, Messrs. Martin, the Misses Lalor, &c. The Committee offered to bring over thc remains of Thomas

Moore, and provide a fitting receptacle for them in the cemetery; but the offer was declined by his widow, with warm expressions of gratitude, as also was a similar one made to the family of the late Richard Lalor Sheil.

The ingenious manner of marking the grounds by letters and figures is due to M. J. O'Kelly, Esq. (one of the gentlemen ap pointed by the Catholic Association as a member of the committee, and now Secretary), a means by which, on reference to the registry,

ORIGIN, HISTORY, AND NATURE OF LITHOGRAPHY.

obstacles which ignorance and

prejudice could throw in its way, and it was not until after years of laborious perseverance, accompanied with the diffi culty of limited means that the inventor, Senefelder, established his reputation and gained for the new art its due degree of admiration. His inability to meet the printing expenses of his works, suggested the thought of devising some cheaper mode of publication. With this view his intention was first directed to several original and curious modes of stereotype, which, however, his circumstances pre vented his maturing. He first experimentalised on metal and composition blocks, and then on plates of copper and tin; also with an etching needle and chemical inks, but found they possessed all the objections found in the stereotyping plan. Experiments on stone slabs followed in rapid succession, and he was pleased to find that he was enabled to take numerous impressions from the original. From this period the art has increased wonderfully and attained a great excellence. Lithography differs from printing by moveable types, wooden blocks or plates, and consists of transmitting impressions to stone, and then working off by a hand-press the quantity required. The attraction and repulsion exhibited by different sub stances towards each other are beautifully applied to prac tical purposes in the process of lithography." The drawing, &c. to be lithographed is written with a peculiar kind of ink, between which and water there is a strong repulsive action, and is transferred by pressure to a fine grained and very porous stone; or a reverse

drawing is made at once upon the stone. When an impression is to be taken, the stone is wetted, and freely absorbs the moisture, except in those places that have been inked, which, therefore, will repel the water and remain quite dry. A roller containing the same kind of we must remark that we notice in this latter the recent introduction ink, is next passed over the stone, and the ink adheres only to those of chapel tombs over the graves, and the yellow wreath decorations places which have repelled the water, the other parts remaining so abundant in the former.
