Sir John Herschel
To:
John Herschel (son)
Date:
[1 April 1865]
Source of text:
JHS 6.58
Summary:
Most of the letter is devoted to a mathematical derivation to show that part of son John's work on errors in geodetic observations is in error; however, part is highly praised by JH. Remainder of letter is clearly intended as a morale booster for John.
