BIRMINGHAM, 1878.

DEAR SIR,—I write to tell you that I like the telescope very much

(5-1/4 in. equatorial); the mirror is, as you say, a gem, and it is

quite a treat to look at the mysteries above. Saturday was a

glorious night, though the Moon was rather too bright. Altogether I

am quite satisfied with the telescope, and the finish is first-rate.

Yours truly,

(_Signed_.)

Mr. G. CALVER.
