7 Camden St. - Thanks WW for the volume of additions, and gives notes and remarks: refers to 'unlatinising' names, dismisses [William] Smyth as 'rather slap dash sometimes', corrects bibliographic references concerning Copernicanism and Roger Bacon. 'The motion of light is first proved by Jupiter's satellites - which establish, geometrically, a motion of the effect called light...Measured motion is geometry, not physics'.
