Has received copies of reprints from Lyell. Points out errors in a printed paper of his. Has been unwell and very busy of late. Would like to add DB's name to the Optical Glass Committee.
Regarding corrections requested by JH in a printed article. Ill health and overwork applies to him also. Pleased to hear of the work of the Optical Glass Committee. Comments on this.
Asks DB to sign a certificate for the candidature of William Ritchie for admission to R.S.L.
Would have answered his last letter sooner but has been confined to his house. Encloses specimen of calcareous spar. Has in the past carried out many experiments on this substance. Is he satisfied with a statement in the Optical Glass report? Missing Transactions for the library.
Sending DB a draft of a paper; comments on quality of a chromatic lens (that of [Charles] Tulley's telescope using Pierre Guinand's glass).
Thanks for paper on light, which he has only just read as it was mislaid. Grateful for the acknowledgement of his scientific labors. Comments and queries regarding the paper in the light of his own experiments. Wishes to reprint parts of it so would be grateful for several plates.
