A most lamented occurrence lately happened in Pembrokeshire: a Boy of 17 and a girl of 14 years of age, children of Evan FRANCIS, who lives on Templeton Mountain, near Narberth, having been recommended to wash themselves in a solution of arsenic, in order to cure a disagreeable complaint which they had contracted, made use of a preparation so strong that it terminated their existence in a short time, and they were both buried on Sunday se'nnight. It is said that the effect of the poison on the bodies was most dreadful, and that it was with difficulty the coffins could be closed upon them. This catastrophe affords an awful warning not to hazard the application of such a virulent poison for the cure of a disorder admitting of a safe and certain remedy; as well as a most instructive lesson to vendors of drugs to be particularly circumspect in enquiring for what purpose such an article is purchased before they suffer it to go out of their hands. On Wednesday a small fishing smack belonging to Milford, called the Express, was run down by a sloop at the entrance of that harbour, and entirely lost; fortunately the crew were saved by the persons on board the latter vessel, after having been some time in the water. The Agenoria, WILLIAMS, from Bangor, and the Ann, JONES from Carnarvon, both bound for London, were captured on the 21st ult. off Folkestone; the latter was carried into France, but the former was re-captured and taken into Deal, the Captain of which was badly wounded, but we are happy to say not dangerously. The corn crops begin to assume a favourable appearance. Grass land is getting into condition again; and a few days such fine weather as we have had during the week, will put the verdant livery of Nature on the hedges, and ensure a plentiful supply of fodder for cattle. On Monday, some oats (the first that had grown on the land latterly recovered by the embankment and inclosure of Malltraeth) were put on board a punt in the navigable canal formed through the marsh; and were conveyed in it to a sloop lying under Bodorgan. The punt was decorated with colours, and drew many persons together, who hailed with joy the first fruits of an undertaking which has cost so much labour and money, and which now promises a handsome return to the adventurers.
