Summary:

Is trying to obtain parts of R.S.P.T. containing the original communication of William Herschel on changes in double stars. Would be glad of JH's assistance. Printer has made mistakes in spite of his proof corrections. Weather most unsuitable for observations due to fog. Is pleased JH is making a synopsis of all the double-star measurements.

Summary:

Is grateful for his prompt reply about his father's papers on double-stars. Had no idea that Angelo Secchi's Means were so inaccurate. Gives the principle on which his own Means are based. The weather has been wretched and most unsuitable for any observations.
