Item 35 - Letter from John Herschel

WW to read the enclosed and give his opinion whether part of the money granted by the British Association for magnetic research, should be used to purchase one or both of the instruments mentioned for the magnetic observatory at [Breslau?]. WW to get Peacock's opinion. Even if they purchase both it will leave a large surplus for which JH can think of no other use 'at home is likely to occur'. JH wishes WW or Peacock would write a review of the magnetic subject for the next quarterly 'to enlighten the public mind about it'.
