Writes to compare notes on sunspot observations.
Comments on remarkable solar activity. JH admits he has no theory to explain sunspots.
Is at present too ill to involve himself in any calculations necessary for making a good optical 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.
