by George Calver

From G. W. Royston Pigott, Esq., M.D., F.R.S., F.R.A.S., &c.

Eastbourne,

October 4th, 1880.

Dear Sir,—Your figuring of the 8-1/2 in. mirror has given me much satisfaction. I see ε¹ ε² Lyræ, and such stars, with 600, very sharp and clear.

I have counted six satellites of Saturn, and the equatorial belt is very distinct.

Last week I happened to observe Jupiter, when a black shadow of a satellite was beautifully notching the limb, at the same time a small pearl-like satellite was about to egress from the belts. I saw, also, six spherical cloudlets on the belts.

Yours faithfully,

(Signed.)

Mr. G. Calver.
