Finest Telescope / ^ Mirror Finished PITTSBURG, May 16.—What is Said to be the finest telescope mirror in the world and the second largest was shipped from the workshop of Dr. John A, Brashear here to the Dominion astronomical observatory in Victoria, Canada. The mirror is 73 inches in diameter, 12 inches thick at the edge and is,pierced centrally by a hole 10 1-S inches in diameter. This mirror is not quite perfect, Dr. Brashear says. The greatest error in the work is one-four hundred thousandth of an inch. The large piece of glass which in its finished state weighs 2 1-4 tons, arrived in Pittsburg in 1914 from Bel­gium, two weeks before the declara­tion of war. i>r. Brashear made the largest tele­scope mirror ever turned out. It is a 100-inch mirror and is in operation in the observatory at Wilson, Cal.
