Thanks for sending the paper in the Quarterly Journal. Comments on the importance of some of the points raised.
RC's book [Observations of the Spots on the Sun] is done. First copy, exhibited at R.A.S. last week, was well reported in R.A.S.M.N. Will send copy to JH.
Formulas for determining rotation rates of sunspots relative to latitude on solar surface. Believes equatorial parts of photosphere are dragged faster than others. Speculates on rotation rate of solid body below (if such exists).
Copy of RC's book will be sent to JH from R.S.L. Thanks JH's son for letter.
If RC's formulas for sunspots are correct, then 'trade-wind theory' is challenged and sun's photosphere may behave as envelope circulating around sun according to laws of planetary motion. Questions formula relating to sunspot velocity.
