* 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 ac- 

 cording to the formula of Sir George Shuckburg, which Sir H. Englefield recommends 

 in the paper where he describes this instrument. Phil, Mag. Feb. 1808.
