in a Providence watching over his future destiny, we are not told. He certainly realised his unique powers, but can hardly have suspected the channel into which they were eventually to be diverted. The one link between Emanuel and his family was his brother-in-law, Eric Benzelius, afterwards bishop, and the sister to whom he was married. In his financial and other troubles he repeatedly appeals to him for sympathy and practical help, evidently not without response. He also asks for intercession with his father, to whom he obviously did not care to appeal direct, having met with too many rebuffs. It is interesting to note that one of the first objects that met his eyes in London was “the magnificent St Paul’s Cathedral, finished a few days ago, in all its parts.” He makes the acquaintance of Flamsteed, the most notable astronomer in England, who was concerned in the founding of Greenwich Observatory and seems to have been something of an astrologer as well. Apparently as the result of this visit, he takes up with enthusiasm the study of astronomy. I have made such progress in it [he says], as to have discovered much which I think will be useful in its study. Although in the beginning it made my brain ache, yet long speculations are no longer difficult for me. I examined closely all proportions for finding the terrestrial longitude, but could not find a single one. I have, therefore, originated a method by means of the Moon, which is unerring, and I am certain that it is the best which has yet been advanced. In a short time I will inform the Royal Society that I have a proposition to make on this subject, stating my points.... I have also discovered many new methods for observing the planets, the Moon, and the stars. That which concerns the Moon and its parallax, diameter, and inequality I will publish whenever an opportunity arises.
