>From The Bury and Norwich Post: Or, Suffolk, Norfolk, Essex, and Cambridge Advertiser ( Bury Saint Edmunds, England ), Wednesday, October 16, 1805. SINGULAR DISCOVERY. - A waiter, who lived at Mr. PARTRIDGE's house ( the Windmill, at Salt Hill ( Slough )) at the time of the sudden death of several gentlemen who dined there about 30 years since, has recently paid the debt of nature himself. The day preceding his death, he sent for the Clergyman of the parish, and, after informing him that he could not die in peace without disclosing what he knew of that calamitous event, made the following recital: " That it was not occasioned, as had been generally supposed, by any preparation in the wine, to fine it, as it arose from the circumstance of some carp having been stewed for a family expected the day before; but from their being prevented coming, the fish was set by in the copper stewpan, in which they had been dressed, where, from its long standing, the corrosive acid in the sauce extracted from the stewpan that quantity of copperas, which proved destructive to most of the gentlemen who partook of this dish, so fatally served up the next day. The fact, he said, was discovered, and known only by the cook and himself; and on imparting it to their afflicted mistress, she enjoined them to secrecy as long as they lived; but that he now found himself in his last moments unable to conceal the mystery any longer!" - Mrs. PARTRIDGE and the cook have both been dead many years,
