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.
On the desirability of one good observatory in India. Thinks Poonah would be the best site. Time not suitable to press for this establishment.
Has no means of knowing what course the University of Cambridge will take in the event of the resignation of James Challis. Hopes that RC will not cease from his astronomical labors.
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.
