CHAPTER I THE SELECTION AND TESTING OF A GLASS "O telescope, instrument of much knowledge, more precious than any scepter! Is not he who holds thee in his hand made king and lord of the works of God?"—John Kepler. If the pure and elevated pleasure to be derived from the possession and use of a good telescope of three, four, five, or six inches aperture were generally known, I am certain that no instrument of science would be more... more...

CHAPTER I COSMO VERSÁL An undersized, lean, wizen-faced man, with an immense bald head, as round and smooth and shining as a giant soap-bubble, and a pair of beady black eyes, set close together, so that he resembled a gnome of amazing brain capacity and prodigious power of concentration, sat bent over a writing desk with a huge sheet of cardboard before him, on which he was swiftly drawing geometrical and trigonometrical figures.... more...
