notes:
The present globe is the only known scientific instrument published by Frost. Portable globes: made of paper or cloth with the ability to be folded down flat, and with a series of drawstrings at the poles in order to make the globe three dimensional, became hugely popular with the burgeoning middle-class of the early nineteenth century who wanted a teaching aid for their children, who might not have the money for a pocket globe by the likes of Newton and Cary.
