Inquires about other sunspot observations made by JH.
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.
Thanks for the photographs WD sent for the dates requested in JH's 1870-4-23.
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.
Comments on sunspot activity; agrees to inclusion of some paragraphs in a paper WD is writing.
Comments on sunspot activity.
Is glad he is pleased with the work of Balfour Stewart and himself. Has applied to R.S.L. for a further grant to carry on the observations and computations for another year. Intends to finance the last year himself. Since the death of his brother he has returned to business.
