From J. C. Harker, Esq.
Kendal, 1878.
Dear Sir,—After four months use of the telescope I had of you (an 8-1/2 in.), I am able to tell you that I am much pleased with its great excellence. The definition of the mirror is very fine, and its performance on the Moon being superb, with so high a power as 700. The stand I find very steady and convenient, and the screw motions very smooth.
I am, dear Sir,
Yours truly,
(Signed.)
Mr. G. Calver.
