A 1719 letter from Henry Barham to Sir Hans Sloane, printed in the Philosophical Transactions, reporting his experiments raising silkworms at Chelsea Park from eggs obtained in Languedoc. He records hatching and spinning dates, counts and weighs cocoons, and measures the silk yield from winding (3,319 cocoons gave about 17 ounces of fine silk). From these figures he estimates the yield from an ounce of eggs and compares it with Augustino Gallo's figures for France and Italy, arguing that silk production in England can match other countries. He also says he can obtain two crops a year and that mulberry trees leaf twice a year in England.
