From D. Traill, Esq.
Balham,
March 5th, 1880.
My Dear Sir,—I have at present to use the telescope, an 8-1/2 in. Alt Azimuth, out of a window, and so at a great disadvantage,—in fact cannot give it a fair trial till I have the house ready for it, meanwhile I use it as occasions offer, and have been highly pleased with it. The views of the nebular in Orion resemble those of Bond’s drawings, and shows immeasurably above my 3-1/4, of course. I think the mirror is perfect from its performance on large stars whose disks are small and round, without rays of any kind. I am thoroughly satisfied.
