Comments on the sun spots he has been observing, and some new phenomenon. Any chance of a visit from JH?
Has returned James Nasmyth's letter and has never seen Warren de La Rue's letter. Comments on Nasmyth's 'willow leaves.' Have been observed at Greenwich Observatory. Thanks for his remarks on the best kind of eye-piece.
Hopes the JH's are all well. Would like an eye-piece made by Mr. Cook[e] or any leading optician on the principles of JH as laid down in his paper in R.S.P.T. Shall he refer the optician to this paper?
Is grateful for his communication on the proposed solar eyepiece. Will call round on his way to town to ascertain if he can leave the manuscript with [Thomas?] Cooke, the instrument maker, so that he can have some idea of the work involved. James Nasmyth will pay attention to screen projection.
