Extract

The object of this communication is to exhibit and describe to the Royal Society a number of flint-glass globes having remarkable internal cavities produced during cooling. Along with these globes there is exhibited for comparison one globe having no perceptible internal cavity.

The making of these globes was shown to me by Mr John Griffin, manager of the St Rollox Flint Glass Works, Glasgow.

The globe having no internal cavity is marked A. A set of globes, four in number, are marked B1 B2, B3, B4, and the sixth globe is marked C.
