8-1/2″ alt. Azimuth.February 25th, 1878.
Dear Sir,—I have found no difficulty in putting up the instrument, and the adjustments do not appear to be hard to manage. It is a very beautiful instrument, and the case with which its movements are made is extraordinary.
I am, dear Sir,
Yours faithfully,
(Signed.)
Mr. G. Calver.
