Having learned to recognize the constellations and their chief stars on sight, one other step, an extremely easy one, remains to be taken before beginning your search for the planets buy the American Ephemeris and Nautical Almanac for the current year. It is published under the direction of the United States Naval Observatory at Washington, and can be purchased for one dollar.
LALANDE recommended to BONAPARTE to double it. The First Consul took his advice: and the French now have tables that greatly surpass those which are used in England. A copy of these have, I understand, been sent to Mr. MASKELYNE, our Astronomer-Royal at Greenwich. The French having at length procured able calculators, are now able to dispense with the English Ephemeris.
On one thing, however, we can decide; life itself is encompassed with gloom; sorrow and anxiety await even those upon whom the stars shed their most golden influence. We know not one day what the next shall bring! no; I repeat it; no in spite of your scheme, and your ephemeris, and your election of happy moments.
The arrangement of the Navigator's Ephemeris then devised has been continued in the British Almanac to the present time. A good deal of matter has been added to the British Almanac during the forty years and upwards which have elapsed, but it has been worked in rather by using smaller type and closer printing than by increasing the number of pages.
Greenwich noon is 18h 51m 48s, Washington mean time; so the ephemeris which gives data for every Greenwich noon may be considered as referred to the meridian of Washington giving the data for 17h 51m 48s, Washington time, every day.
At high acceleration the Sirius drove toward the Jupiter-Earth-North plane, and Brandon calculated from his own bearings and from the current issue of the "Ephemeris" the time at which Stevens' reply should be received. Two minutes before that time he was pacing up and down in front of the ultra-receiver, and fifteen seconds after it he snapped: "Come on, Perce, get busy! Shake a leg!"
The names in hyphens are those given in a paper on the nautical instrument of the Arabs by Jas. The learned secretary appears not to have heard the legend of Shaykh Majid, for he alludes to the "Majidi Kitab" or Oriental Ephemeris, without any explanation. The western points are named like the eastern. North-east, for instance is Ayyuk el Matlai; north-west, Ayyuk el Maghibi.
"In order," says he, "to defray the expense of the Ephemeris for two years, I have been obliged to compose a vile prophesying Almanac, which is scarcely more respectable than begging, unless from its saving the Emperor's credit, who abandons me entirely, and would suffer me to perish with hunger." These Ephemerides, from 1617 to 1620, were published at Linz in 1616.
Although on that occasion, owing to the position of the earth, invisible in the northern hemisphere, Sir Thomas Brisbane's observatory at Paramatta was fortunately ready equipped for its recapture, which Rümker effected quite close to the spot indicated by Encke's ephemeris. No great comet is of the "planetary" kind.
For the fish, harried this way and that by so many of your disciples, is exceeding shy and artful, nor will he bite at a fly unless it falleth lightly, just above his mouth, and floateth dry over him, for all the world like the natural ephemeris.
