Nebulous nature of some stars. Recent reports on variability of some nebulae.
JH received and will insert HA's list of nebulae into JH's catalogue. Progress of catalogue. Wishes JH had earlier knowledge of [G. F. J. A.] Auwer's reduction of William Herschel's nebulae, which JH just received.
Reduction of JH's catalog of nebulae will not be completed before Christmas. HA's success in discovering nebulae and novae. Has compared positions of all nebulae observed by both JH and William Herschel; very few show evidence of shift. Thanks for offering HA's observations, but space in catalog is too limited.
[JH's summary of letter] Instructions and corrections relative to data on nebula for JH's catalogue.
Gratitude for receipt of JH's Cape Results.
Comments on JH's work on nebulae and offers some of his own nebula observations. HA would be greatly honored if JH would include HA's observations in the catalog JH is preparing.
More about the nebula catalog JH is preparing [see HA's 1862-3-12], and still wondering if there is some way HA's observations might be used.
Is sending JH a list of 38 nebulae, their positions reduced to 1830, and described using the terms that JH uses. Comments on some of the difficulties in identifying the nebulae, and includes reference to other astronomer's work.
Is sending JH several lists of nebulae, and comments about some of the items. [Almost illegible.]
Is writing to clarify some earlier information about a list of nebulae that he had sent to JH.
