ECLIPSES, 1896. (Astronomical calculations made expressly for The Tribune Almanac by Berlin H.
Wright, Penn Yan, N. Y. There will be four eclipses this year-two each of the sun and moon: I. An annular eclipse of the sun February 13, invisible in the United States. A partial eclipse will be visible in South Africa, at Cape of Good Hope, quite large, and in Brazil, very small. This eclipse returns again February 19, 1914, and in the Antarc. tic Circle. II. A partial eclipse of the moon February 28, invisible in America.
In Europe, Asia and Africa, it will be seen, of 10 digits in size. It returns again March 10, 1914, and will be larger, and visible in North and South America.
III. A total eclipse of the sun, August 8 and 9, invisible in America; visible in Europe and Asia, the total phase being seen in Siberia and Yezo. This returns again August 21, 1914, central in British
N America, Norway, Russia, India.
IV. A partial eclipse of the moon August
OF AUGUST 22-23.

The first six digits occur at No. 2, the last six in No. 4, and when largest, nearly three-quarters of the moon, in NO. 3. Lunar Eclipse,

*August 23. TO FIND THE TIME OF GREATEST ELONGATION OF POLARIS.
TABLE I. By adding the numbers in the annexed table for any given latitude to the time of meridian passage of Polaris (the Pole Star), in Table III, the time of its greatest western elongation is found. If the same number be subtracted instead of added, we get the time of greatest eastern elongation. At the time of either elon

MEAN TIME OF SIDEREAL NOON, OR MERIDIAN
PASSAGE OF THE VERNAL EQUINOX AT WASHINGTON, D. C.,
(For other places, add 9.83 seconds for each hour of longitude east of Washington, and subtract 9.83 seconds for each hour of
longitude west of Washington.)
TIMES OF UPPER MERIDIAN PASSAGE OF POLARIS, OR NORTH STAR, 1896. Surveyors and civil engineers may obtain the variation of the magnetic needle for any place in the United States by directing their compass to the North Star (Polaris) when it is upon the meridian, as given in the table below, for the upper culmination: or 11 hours 58 minutes 2 seconds, before or after, when the star is on the lower meridian. Exact local time is used in the table, and the timeplece used must be correct, and the bearing of the star taken promptly on time, and that bearing will be the true variation of the needle. An error of only a few seconds in the timepiece will vitiate the bearing found; therefore, it will be much better to take the bearing when the star is furthest east or west, at its greatest elongation, as observations made upon it then are not affected materially by small errors of timepieces. To use this table for places west of Washington, add 9.83 seconds for each hour of longitude east of Washington, and subtract 9.83 seconds for each hour west of it. From February 1 to August 1, use the lower culmination.
