My Dear Sir,—I have much pleasure in informing you that the very first time I saw Saturn through your 6-1/2 inch reflector, the definition of the planet was far superior to anything I had observed before, even with a good 4-1/4 inch refractor; and on another occasion I was greatly pleased with the clear and easy view of the “Comes” to ε Boötis. But even without including the stars, the views of Saturn and Jupiter through my 6-1/2 inch mirror do alone (in my opinion) well repay the cost of the telescope.
Yours truly,
(Signed.)
Mr. G. Calver.
