Apologizes for citing nonexistent error in JH's Outlines Astr. [see AE's 1851-3-12].
Describes second edition of AE's phonetic Latinis alphabet, referred to by JH in Admiralty Manual. Sent copy to C. K. J. Bunsen. This will be discussed at Society of Arts's Education Exhibition on 31 July. Encloses printed circular. Hopes JH will attend.

Would like JH's support for his candidature for the R.S.L.
Will bring down his R.S.L. form to Collingwood. Regarding the phonetics of Hindustani.
His letter and accompanying packet arrived for which accept his best thanks for the valuable contribution to the literature of physical geography. Is gratified by JH's commendation of his own Physical Atlas.
New method for constructing circular lenses up to 10-feet diameter for £50. Focusing power sufficient to melt metals. Wants to send 3-inch sample to JH.
Sends small lens. Its components neither parallel nor concentric; contains water. Suggests new polishing method. Estimates 4-foot lens would cost £7-£8. [JH Note: Tested and returned lens. Noted advantages and deficiencies and suggests improvements. Listed others who built similar lenses.]
Lens safely returned. Not aware of lenses in 1851 Exhibition or of C. F. Sturm's solid lenses. Notes advantages of plate glass. Offers to make three foot by three foot square lens. Recognizes limitations for use in astronomy; hopes for other applications.
Requests permission to publish JH's and AW's 1843-1844 correspondence in 'Journal of Industry.'
Queries regarding JH's star lists. Sending magnetic information from A. T. Kupffer. Regarding the distribution of nebulae.
Astronomical queries, with particular reference to the Coal Sack. [Probably to JH, but unclear from letter.]
Is grateful for his constructive letter on the Coal Sack. Regarding the work of the Schlaginweit brothers.
