present season more than ever entitled to partake of the recreations
offered us, whether theatrical, musical, pictorial, saltatorial, philosophical, or scientific. And so, while simple-minded people are looking into the new almanacs to test the accuracy of the predictions, I must try to fill a page or two with such matters of talk as will bear reproduction in print. First of all, among the discussions and communications at the Astronomical Society, it is stated that the term 'meteoric astronomy' is one which we shall shortly be able to use with almost absolute certainty, as M. Petit of Toulouse has succeeded in determining the orbits of meteors relatively to the sun as well as to the earth. His conclusions are considered valuable, especially with respect to the meteor of August 19, 1847, which, it appears, came 'from the regions of space beyond our system;' having, as is estimated, occupied more than 373,000 years in passing from its point of departure to its fall in the North Sea, near the shores of Belgium! This is another addition to our knowledge of meteoric phenomena which affords promise of further results. Certain members of the same society are still at work on what has been a tedious task--the restoration of the standard yard, rendered necessary, as you will remember, by the destruction of the original in the Parliament-House conflagration, more than ten years ago. The work proceeds slowly but surely, as the extremest pains are taken to insure accuracy, the measurements, bisections, and graduations being read off with a microscope. When finished, it will be centuplicated or more, if necessary, and, as is said, a copy deposited in every corporate town in the kingdom. This restoration of the standard is not so easy a task as would be commonly supposed, for apart from the determination of the yard with mathematical accuracy, alternations of heat and cold have to be taken into account; for, as |
