Writes to compare notes on sunspot observations.
Has no idea whether the sunspots appeared suddenly or gradually. The Kew people may be able to help in this matter. Comments on some more sunspots.
Intends bringing the subject of sunspots before the B.A.A.S. next September and would therefore like JH's views on whether in his opinion these spots are mechanical or magnetic. Also any other comments would be welcome.
Is grateful for JH's note. Agrees with him about the mystery of the sunspots. Is awaiting some heliographs from Ely. Is inquiring from Kew as to any recent magnetic disturbances that may coincide with the appearance of the sunspots. Is grateful for Alexander Hershel's information.
Comments on remarkable solar activity. JH admits he has no theory to explain sunspots.
