Mr. G. Calver.
From J. T. Stevenson, Esq.
Auckland, New Zealand, 1877.
Dear Mr. Calver,—Since writing to you I have been observing with the 6-1/2 in. equatorial telescope, and I have much pleasure in informing you that I am greatly pleased with its performance. The definition of the planets is beautiful.
I am happy to inform you that I have found a most minute crater in Picard a, it is much smaller than the test crater (mentioned in Cel. Obj., by Webb, page 83) in same formation. I wrote to Mr. Webb about it, and since then I have seen it distinctly; it is another proof of the excellence of your telescope.
Yours truly,
(Signed.)
Mr. G. Calver.
