an excellent painter in enamel. He was born in Stockholm, and bred a jeweller; which profession he intended to follow in England; but changed his design, and went into the country, where he taught children to draw. He there engaged a gentleman's daughter, who was one of his scholars, to promise him marriage; but the affair being discovered, he was thrown into prison. In that confinement, which lasted two years, he studied enamelling; an art to which he fixed, on his return to London, and practised with the greatest success. The prices he is said to have obtained for his work are almost incredible; but being engaged in a very large design for the court, and Queen Anne dying before it was completed, he ran in debt, his goods were seized by execution, and he fled to France; where he changed his religion, was countenanced by the regent, and obtained a pension of £50l. per annum, but died suddenly at Paris in 1726. There is a large piece done by him at Kensington, representing Queen Anne sitting, and Prince George standing by her; and at Bedford-house is another very large plate of the duke's father and mother.

It grows to seven or eight feet long, is about the thickness of a man's arm, and very small and taper towards the tail. Its back is of an olive colour; its belly yellow, and covered with very regular and elegant triangular scales. It feeds on frogs, &c., but is very poisonous, and its bite extremely fatal.
