We had another Lecture from Mr. Williams to day, with an explanation of the different optical Instruments, that are most commonly made use of. But there was such, a flocking to see 45through the microscope, and the magic Lantern, and the camera obscura, that something got broke, and Mr. Williams, shew nothing more after it. Weather very warm, several of us, bath'd in the River this afternoon.
