TitleLetter from Edward Sabine, Woolwich, to [Charles] Wheatstone
Date11 April 1845
DescriptionRefers to a passage from Mrs [Mary] Somerville’s writing which Wheatstone has transcribed regarding the ‘magnetic pole’, for which Sabine offers an explanation. Sabine remarks on Mr [William] Whewell’s ‘philosophy of the inductive sciences’. Discusses mistakes made which have ‘impeded’ the ‘progress of terrestrial magnetism’. Remarks on the locality in each hemisphere ‘where the dip is 90°’, and ‘where the force forms a center [sic] of greatest intensity around which the isodynamic lines arrange themselves’. Refers to the place ‘where Captain Ross observed the needle’. Discusses the isodynamic centres. Sabine remarks on ‘the general arrangement in the southern hemisphere is strictly analogous’. Discusses the longitudes and refers to the observations from the Antarctic expedition. Refers to the ‘geographical branch of the magnetic observations’.
