The following are quotes on Towneley:

“The association of physical science with mountains goes back, as far as we need to be concerned, to the seventeenth century; to Perier’s ascent of the Puy de Dome, in order to demonstrate that the height of the barometer fell as the altitude increased, and Richard Towneley’s ascent of Pendle Hill when he was discovering his ‘hypothesis’, still wrongly called ‘Boyle’s law’.”
