Dear Sir,—I have mounted the 5-inch speculum on a simple equatorial and it works well. I am sure it will turn out a fine glass and I shall not regret the time and pains I have spent over it. It is not quite in adjustment yet, when it is it will afford me a treat. I have just tried it once on the Orion Nebula and Trapezium, details of Nebula well seen, and the 5th star in Trapezium easy.
I am, Yours truly, F. G. L.

Dear Sir,—I have thoroughly tested the speculum, and am pleased to tell you it stood its trials well.
