Nebulous nature of some stars. Recent reports on variability of some nebulae.
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.
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.
