page 117 ---telling time by the Southern Cross----southern constellations

It was on Sunday, the 29th of June, that according to our ship's reckoning we were to cross the equator. As the sea was pretty calm, mass was celebrated on this day. The solitude of the place, the silence and grandeur of the element to
which the little vessel was confided, between the two hemispheres and in the middle of the vast ocean, could not fail in the moment when transubstantiation was announced by the sound of theWestern hemisphere by George F. Cram Maps, 1883. Thanks to C. Miranda Chor !drum, profoundly to affect every mind, but particularly those who then reflected on the Providence of nature, and on the mysterious metamorphosis of all things. The day passed over quietly with a constant S.E. wind; even Neptune and his strange retinue were not allowed to excite a disturbance on board the ship, by the usual ceremony of baptising those who crossed the line for the first time. The night was bright and clear; the poles of the heavens were already resting on the horizon, and the full moon hung above our heads in glorious majesty; Vega, Arcturus, Spica, Scorpio, in which Jupiter just then shone, and the feet of the Centaur, were bright in the firmament; the Southern Cross had attained a perpendicular position indicating the hour of midnight, when, according to calculation we were at the place where heaven and earth were in equilibrium and crossing the equator steered into the southern hemisphere. With what ardent hopes, with what inexpressible feelings did we enter this other half of the world, which was to present us with an abundance of new scenes and discoveries! Yes, this moment was the most solemn and sacred in our lives. In it we saw the longings of earlier years accomplished, and, with pure joy and enthusiastic foreboding, indulged in the foretaste of a new world so rich in the wonders of nature.

It was not till we had passed the equator, that the constant S.E. wind began to equal in strength the N.E. wind of the northern hemisphere. Violent rains were less frequent, but in their stead insulated groups of clouds of various forms were piled up in the blue ether. The nights, on the other hand, were more serene, and the southern constellations, new to us as pilgrims from the north, though far inferior in number and splendor to those of the north, shone brightly in the azure firmament. Falling stars illumined the night more frequently than in the northern zone, andNoctiluca miliaris from "Illustrirtes Thierleben", 1879. Thanks to Princeton U. generally fell towards midnight in the south, and towards morning in the northeast. The temperature of the water, still more that of the air, appeared to become considerably lower than that in the same northern latitude, but the moisture of the air, phosphorescence and gravity of the sea water began to increase. Our frigate rapidly cut the deep blue waves of the southern ocean, which, as they dashed against the stern, fell, on cloudy days, in numerous rainbows, or in the night, filled with countless luminous animals (Noctiluca oceanica nob.), shone like sparkling fire. Here, too, as in the northern torrid zone, swarms of flying-fish flew around, and the swift tunny-fish kept pace with our vessel. The sun appearing in a glow of red behind thick mists, or the pale moon, afforded us a majestic prospect when they rose or sunk into the ocean.
