Page 29 - The two great stars which mark the summit and the foot of the Cross having nearly the same right ascension, it follows hence, that the constellation is almost perpendicular at the moment when it passes the meridian.
Page 28 - We saw distinctly, for the first time, the cross of the south, only in the night of the 4th and 5th of July, in the sixteenth degree of latitude. It was strongly inclined, and appeared, from time to time, between the clouds, the centre of which, furrowed by uncondensed lightnings, reflected a silver light. The pleasure felt on discovering the southern cross was warmly shared by such of the crew as had lived in the colonies.
Page 28 - A traveller has no need of being a botanist to recognise the torrid zone on the mere aspect of its vegetation ; and without having acquired any notions of astronomy, without any acquaintance with the celestial charts of Flamstead and De la Caille, he feels he is not in Europe when he sees the immense constellation of the Ship or the phosphorescent clouds of Magellan arise on the horizon.
Page 28 - ... of space remarkable for their extreme blackness, give a particular physiognomy to the Southern sky. This sight fills with admiration even those who, uninstructed in the branches of accurate science, feel the same emotion of delight in the contemplation of the heavenly vault, as in the view of a beautiful landscape, or a majestic site.

Page 112 - The most remote were about 9 or 10 miles distant from each other, in a line differing little from the course of the meteor. It is therefore probable that the successive masses fell in this order, the most northerly first, and the most southerly last. We think we are able to point out three principal places where stones have fallen, corresponding with the three loud cannon-like reports, and with the three leaps of the meteor, observed by Mr.
Page 29 - It has been observed at what hour of the night, in different seasons, the Cross of the South is erect, or inclined. It is a time-piece that advances very regularly near four minutes a day, and no other group of stars exhibits, to the naked eye, an observation of time so easily made. How often have we heard our guides exclaim in the savannas of Venezuela, or in the desert extending from Lima to Truxillo, " Midnight is past, the Cross begins to bend!
