Triumphs and wonders of the 19th century, the true mirror of a phenomenal era, a volume of original, entertaining and instructive historic and descriptive writings, showing the many and marvellous achievements which distinguish an hundred years of material, intellectual, social and moral progress .. . nn, of Vienna, the highest authority on this subject,said that it was the most comprehen-sive study of a meteors path ever ac-complished. Six years were spent inmaking the computations. Self-illumined by the heat evolved instriking the various layers of the earthsatmosphere, it became sufficiently brightto be first seen when seventy milesabove the surface of the earth. It waswithin forty miles of touching us atthe time it was over the Hudson River,when the great heat acquired by itsrapid transit caused it to burst into twomasses, which — like Hiela:s comet.—continued to pursue separate courses,side by side, until they were lost toview in their ascending flight, being lastseen from the deck of a vessel off theisland of Nantucket. No part of the fire-ball struck theearth. Its orbit was an hyperbola, acurve not often found in nature, andsuch that it can never come near usagain unless, by the superior attraction of some celestial body, its coursemay be changed, and a new orbit JAMES H.

Its main purpose was to extend astronomical know-ledge, so that navigators might better find the position of their ships at institution retains its prominence. All the longitudes on our maps arereckoned from it, and Greenwich time is used on every ship that traversesthe ocean. The Nautical Almanac, issued by the Observatory, was anindispensable part of the outfit of every sea captain until, in 1852, theUnited States provided its own American Ephemeris, a collection of tablesof the motio
