Sends JH's 'On Atoms' to WP.

Many thanks for JH's article on the telescope; will read it with much interest. Has employed an assistant to prepare drawings of the nebula. The six-foot reflector requires repolishing.

Offers assistance for JH's proposed catalogue of nebulae. Will send estimated positions of recently discovered nebulae.

Thanks WP for WP's paper on nebulae and on WP's giant reflecting telescope. Comments on and/or raises questions about various nebulae.

Assistant Samuel Hunter will send WP's observations to JH. Original intent was to confirm JH's nebulae, but WP soon found new nebulae. Trouble finding good assistants. Note on new transit instrument.

Still searching for journal of WP's observations. Notes on micrometer used in measuring nebulae positions. WP's assistants are not qualified to make new measurements.

Encloses letter from G. J. Stoney, who had journal of WP's nebulae observations. Hopes WP's observations will be helpful for JH's proposed catalogue of nebulae.

Discusses plans for a memorial for Thomas Maclear. Requests change in manner in which WP records positions of nebulae observed at WP's observatory.

Preparing classified index of observatory journals, but information will not be accurate enough to help JH. G. J. Stoney is too busy to help remeasure nebulae positions.

Has received letter from Lord Palmerston [Henry John Temple] approving JH's request for a memorial for Thomas Maclear.

Laurence Parsons (Lord Oxmantown) has gone to Ireland to discharge his duties of High Sheriff. Sends finished proof of the engraving of Orion; comments on this. Has not worked on the nebula himself for many years. [J. K.?] Hunter was a good artist.

Thanks WP for having sent chart of the Orion nebula. Comments on its quality.
