Comments on remarkable solar activity. JH admits he has no theory to explain sunspots.
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.
Is anxious to have an astronomical eye-piece based on JH's principles. Encloses communication from Messrs. Horne and Thornthwaite, who would like details for their employee, [W.?] Ackland, to work from.
Is at present too ill to involve himself in any calculations necessary for making a good optical eyepiece.
Is grateful for his reply. Hopes he is feeling better. Escaped worst of the winter by expedition to Algeria, though the results were disappointing. Comments on some of his observations. Feels sure [W.?] Ackland will be able to construct a suitable eyepiece.
Cannot explain the peculiarities of the blood corpuscles of the Camelidae; maybe similarity between camels and ostriches arises from adaptation rather than common ancestry.
