31 S THE MATHEMATICAL PRINCIPLES [BOOK 1L of the lesser globe, which is in the duplicate ratio of the velocity, was to the whole resistance as 0,56752 to- 0,61675, that is, as 45,453 to 49,396 ; whereas that part of the resistance of the greater globe is almost equal to its whole resistance ; and so those parts are nearly as 318,136 and 45,453, that is, as 7 and 1. But the diameters of the globes are 18f and 6
