Incidentally, it may be mentioned that much most interesting work may be done even with an opera glass, as a few minutes' systematic observation on any fine night will prove. Newcomb and Holden assure us that "if Hipparchus had had even such an optical instrument, mankind need not have waited two thousand years to know the nature of the Milky Way, nor would it have required a Galilei to discover the phases of Venus or the spots on the sun." To amplify the thought, if that mighty geometer and observer and some of his contemporaries had possessed but the "common telescope," is it not probable that in the science of astronomy the world would have been to-day two thousand years in advance of its present position? * * * * * ARCHAEOLOGICAL DISCOVERIES AT CADIZ. Those who have had the good fortune to visit Andalusia, that privileged land of the sun, of light, songs, dances, beautiful girls, and bull fighters, preserve, among many other poetical and pleasing recollections, that of election to antique and smiling Cadiz--the "pearl of the ocean and the silver cup," as the Andalusians say in their harmonious and imaginative language. There is, in fact, nothing exaggerated in these epithets, for they translate a true impression. Especially if we arrive by sea, there is nothing so thrilling as the dazzling silhouette which, from afar, is reflected all white from the mirror of a gulf almost always blue. The Cadiz peninsula has for centuries been legitimately renowned, for, turn by turn, Phenicians, properly so called, Carthaginians, Romans, Goths, Arabs and Spaniards have made of it the preferred seat of their business and pleasure. In his so often unsparing verses, Martial, even, celebrates with an erotic rapture the undulating suppleness of the ballet dancers of _Gades_, who are continued in our day by the _majas_ and _chulas_.
