Lecture on Stephen Grays discoveries in electricity

A lecture at the Charterhouse, London on Stephen Gray's discoveries in electricity. In the early eighteenth century, Gray demonstrated that charges of electricity could be conducted by some materials for distances as great as 765 feet, while others did not conduct electricity at all. Eventually, he was able to send charges through 88 metres of wire suspended on silken threads to operate an electroscope - an instrument used to detect static electricity. By sending an electrical signal from one place to another, Gray established the basic principle of the electric telegraph

Our forefathers fought for a principle - there is no fight i

Our forefathers fought for a principle - there is no fight in us. Illustration shows two scenes, at top left is The Spirit of 76 showing a family about to sit down to tea, as boxes of tea are visible, through a window in the back of the room, floating in Boston Harbor. The father, who has just entered, states: Away with that tea or you're no daughter of mine! Not a drop in this house until the hateful tax is taken off! At bottom right is The Spiritless 1907 showing a family sitting at the dinner table where the grandfather is about to carve the beef, he states: Ain't it a shame the prices they charge for beef. But we've got to have it, Trust or no Trust. At the bottom left, disgruntled patrons exit a Market, counting their change. Date 1907 November 13.
