'There was :once a week, in John Wilkins's chambers at Wadham College,' says Enoch. 'For that is where the Experimental Philosophical Clubb met. Christopher Wren, Robert Boyle, Robert Hooke, and others you ought to have heard of. By the time I got there, they'd run out of space and moved to an apothecary's shop – a less flammable environment. It was that apothecary, come to think of it, who exhorted me to make the journey north and pay a call on Mr. Clarke in Grantham.'
