Inquires about other sunspot observations made by JH.
Thanks for the photographs WD sent for the dates requested in JH's 1870-4-23.
Comments on sunspot activity; agrees to inclusion of some paragraphs in a paper WD is writing.
Has written to Kew Observatory to send on the photographs.
Has just learnt that some negatives were sent to his former place of residence. Will forward them when he goes to the City. A vote has been made from the Donation Fund of the R.S.L. for six copies of the Kew Solar negatives.
Would like to incorporate JH's suggestions in his paper and he has revised the numbers. Made an attempt to photograph the moon while totally eclipsed, but was unsuccessful.
