In the communication of Dr. Robinson to the Royal Irish Academy, previously referred to, he laid before that body a report of a most valuable discovery made about eighteen years since in King's County. It consisted of a large bronze vessel, which contained, in addition to various relics acquired by the late Dean of St. Patrick's and other individuals, thirteen litui or trumpets of bronze, the largest having their seams rivetted; thirty-one bronze celts of different sizes; twenty-nine spear-heads; three gouges; and thirty-one bells, believed to be for sheep or cattle--all of bronze. The account of this remarkable discovery had been reserved for sixteen years, owing to the strange suspiciousness of the Irish peasants by whom it was found, who imposed on the purchaser the promise of keeping the details secret during their lives. The last of them died in the winter of 1848, and then he felt himself at liberty to communicate the particulars which Dr. Robinson laid before the Academy. "The vessel, which is now in the collection of the Earl of Rosse, was found in the townland marked Dooros Heath, in sheet 30 of the Ordnance Map of King's County, near Whigsborough, in what appears from the description to have been a piece of cut-out bog, about eighteen inches below the surface. It is composed of two pieces neatly connected by rivets. The bronze of which the sheets are formed possesses considerable flexibility, but is harder than our ordinary brass, and it must have required high metallurgic skill to make them so thin and uniform. On the other hand, it is singular that neither in this or any other bronze implements with which I am acquainted, are there any traces of the art of soldering; if it might be supposed objectionable in vessels exposed to heat, yet in musical instruments this would not apply. Such vessels have often been found, but the contents of this are peculiar. When discovered (without any cover) it seemed full of marl, on removing which it was found to contain an assortment of the instruments which may be supposed most in request among the rude inhabitants of such a country as Ireland must have been at that early epoch.... It seems likely that the collection was the stock of a travelling merchant, who, like the pedlar of modern times, went from house to house provided with the commodities most in request, and it is easily imagined that if entangled in a bog with so heavy a load, a man must relinquish it.
