The author was the son of a Huguenot pastor at La Rochelle, and was brought to England on the Revocation of the 

 Edict of Nantes hid in a tub. After receiving Holy Orders he became chaplain to ' the Princely Chandcs ', and vicar of 

 Little Stanmore, Middlesex, where Handel played the organ. 



' He was the inventor of a machine called the planetarium, which served to determine the exact distances of 

 the heavenly bodies according to the systems of Newton and Copernicus. He also erected a ventilator in a room over the 

 House of Commons ' (D. N. iJ.)— the prolitic parent of many successive extractors of public money, if not of bad air.
