first performed outside on the terraces overlooking the garden, a connection with Desaguliers' new water works seems probable. Desaguliers advised the Duke of Chandos on many projects and appears to have been distracted from his parochial duties by his other interests. The Duke once complained that there were unreasonable delays in burying the dead but this was attributed to the curate who was left in charge of the church. Engineering interests Desaguliers applied his knowledge to practical applications. As well as his interest in steam engines and hydraulic engineering (in 1721 he cured a problem in the Edinburgh city water supply) he developed expertise in ventilation. He devised a more efficient fireplace which was used in the House of Lords and also invented the blowing wheel which removed stale air from the House of Commons for many years. Desaguliers studied the movements made by the human body when working as a machine. He befriended the strong man, Thomas Topham, and although there is no firm evidence that he used Topham as a body guard, Desaguliers recorded several of the feats that he performed. Desaguliers was a parliamentary adviser to the board concerned with the first Westminster Bridge. This much-needed second crossing of the Thames was not completed until 1750, after his death, but construction work resulted in the demolition of Desaguliers's home in Channel Row. Desaguliers also made significant contributions to the field of tribology. He was the first to recognise the possible role of adhesion in the friction process. For this contribution, he was named by Duncan Dowson as one of the 23 "Men of Tribology". Freemasonry Desaguliers was a member of the Lodge which met at the Goose and Gridiron tavern. This Lodge, later known as the "Lodge of Antiquity", joined with three others lodges on 24 June 1717 to form what would become the Premier Grand Lodge of England. The new Grand Lodge grew rapidly as more lodges joined and Desaguliers is remembered as being instrumental in its early success. He became the third Grand Master in 1719 and was later three times Deputy Grand Master. He helped James Anderson draw up the rules in the "Constitutions of the Freemasons", published in 1723, and he was active in the establishment of masonic charity. During a lecture trip to the Netherlands in 1731 Desaguliers initiated into Freemasonry Francis, Duke of Lorraine (1708 – 65) who later became Holy
