His globes range from 2 3/4 in to 27 in diameter and he was elected a Fellow of Royal Society in 1728 and subsequently his globes then bear the initials FRS in the cartouche. Following Senex's death the copper plates were used by other globe makers and they were revised to show California as a peninsular and George Anson's circumnavigation of 1744. George Adams (1709-1772) instrument maker to King George II purchased the copper plates from Senex's widow in the 1750's and James Furguson bought the other larger globe copper plates, tools and moulds.
