- ↑ I made use of the portable barometer of Sir Henry Englefield, Bart. which seems particularly suited for the geological traveller. The heights have been calculated according to the formula of Sir George Shuckburg, which Sir H. Euglefield recommends in the paper where he describes this instrument. Phil. Mag. Feb. 1808.
