At Chiswick, co. Middlesex, while drinking tea with Mrs Mayersbach, widow of the celebrated water-doctor of that name, Mr. Louis Weltjie, late clerk, cook, and purveyor to the Prince of Wales. He appeared to be good health during the course of the day and the evening; but just as he began to drink the second cup, he suddenly fell back and expired. Being a very gross and corpulent man, it is supposed his death was occasioned by a stroke of the apolexy. The history and fortune of this man are somewhat singular. He was memorable example of the effects of industry. He was by birth a German, and formerly sold cakes and gingerbread about the streets. He came originally to this country with the recommendation of the present Duke of Brunswick. By the gradual advances of diligence and prudence, he became master of one of the most fashionable taverns in the metropolis, which was the resort of the highest of our nobility. His house, indeed, hardly came under the denomination of a common tavern, as it was chiefly supported by clubs, confiding of the most distinguished characters in the fashionable world. After having been in possession of this house for many years, and acquired in it a considerable fortune, Mr. W. was appointed clerk of the kitchen to the Prince of Wales. By what means he got recommended to the notice or favour of his Royal Highness we know not; but, after he received the appointment of chief cook and clerk of the kitchen, he soon became purveyor to Carlton house and the Pavillion at Brighton, in which situation he acquired a considerable fortune; and continued some years, till the death of his daughter, an only child, rendered the scene of domestic misfortune too painful for his feelings. This daughter, some years since, having taken a liking to a young cook, the subordinate of Weltjie, married him, which greatly excited the indignation of her father, who preferred his complaints to his royal patron. He represented with great indignation the disgrace and degradation of has family by so humble an alliance, and warmly solicited the dismissal of the offender. The good sense of his Patron saw the matter in a very different light, which induced him to observe, that the inequality was not so great as to outrage the feelings or wounded the pride of a man who could not entirely forget his own former situation. He was, therefore, advised to make the best of the affair, and reconcile himself cordially with his son-in-law and daughter. Instead of prudently adopting this counsel, the enraged father persisted in urging the discharge of the offender against the dignity of his family, threatening to consign both husband and wife to indigence; to prevent which the illustrious person alluded to discharged Weltjie himself, and put the son-in-law into his lucrative situation. Some other unfortunate circumstances conspired with the loss of this child to make him desirous of relinquishing his employment; and he accordingly retired to a house at Hammersmith, which his own taste considerably improved, and where he lived with true hospitality. It should be observed to the honour of Mr. W. that, when he retired from the service of the Prince of Wales, his accompts, at his own desire, were inspected by his royal highness's four trustees, at the head of whom was the late Earl of Southampton, who pronounced Mr. W's statement fair, just, and disinterested beyond example. Mr. Pitt, we are assured, also bore ample testimony to the accuracy and fairness of Mr. W's accompts. We conceive it an act of justice to pay this tribute to the memory of a worthy man, whose elevation in life and splendid fortune subjected him to the rancour of envy and the assaults of detraction. He possessed an excellent understanding; and, if had received the advantages of Literature, he might have figured upon a much higher stage of life than that which Fortune had allotted to him. Like all public and all prosperous men, he had many enemies; but his good humour, manly spirit, and liberal conduct, raised him many sincere friends among those who really understood his character; and he has not dropped into the grave without exciting among those friends a strong sentitment of regret. - A will has been found in his iron chest, by which he bequeathed the whole of his property to his brother, reserving to his wife an annuity of 50l. for her life only. This very unequal distribution, it seems, has since been altered; and the brother, through the kind and humane interference of a friend, has been induced to cancel the provisions of the will, and make such allowance to the widow as that friend should deem reasonable and liberal. In consequence of this arrangement, the best understanding now prevails amongst the parties thus interested.
