20 May 1871
I have the pleasure herewith to forward copies of printed results of the Sydney Observatory. Few Astronomical Results have been published recently the late Astronomer devoted himself chiefly to the Base Line operations of the Trigonometrical Survey of the Colony and the transit instrument is much inferior to the one at Melbourne so the results are not deemed worth publishing.
I have been devoting all my time to measurements of circumpolar ?? double stars but results are not yet printed.
I shall be glad at all times to co-operate with you in any matters of science and to exchange printed results.
Yours very truly

P.S. The newspaper report of papers on nebula about γ?? Argus is only form in which it is printed.
