Stuk 95 - Letter from John Herschel

3 pp

Collingwood - JH encloses a note he got from George Airy with a suggestion identical to the course JH 'had prepared to take having first written to the Sec. of the B. Assoc. to enquire with whom we are to communicate on their part'. If WW and Peacock approve he will write to Edward Sabine accordingly. Has WW any 'ideas' generally on magnetic observations: It strikes JH that a great deal of the existing machinery could be dispensed with and 'what we now need is in the nature of magnetic surveys, with a few fixed establishments to keep up connexion between the past and future'.
