Being the latter part of the 69th, and the beginning of the 70th,

year of the Independence of the United States of America; the 6558th year of the Julian Period; the latter part of the 5605th and the beginning of the

5606th, year since the creation of the world, according to

the Jews; the 2598th year (according to Varro) since the foundation

of Rome; the 2592d year since the era of Nabonassar, which has been

assigned to Wednesday, the 26th of February of the 3967th year of the Julian Period, which corresponds, according to the chronologists, to the 747th, and, according to the as

tronomers, to the 746th year, before the birth of Christ; the 2621st year of the Olympiads, or the first year of the

656th Olympiad, beginning in July, 1843, if we fix the era of the Olympiads at 7751 years before Christ, or at or about the beginning of July of the year 3938 of the Julian

Period; the latter part of the 1260th, and the beginning of the 1261st

year (of twelve lunations) since the Hegira, or flight of Mahomet, which, as is generally supposed, took place on the 16th of July, in the year 662 of the Christian era.

The sign + is prefixed to the latitude, or declination, of the Sun, or other heavenly body, when north, and the sign when south; but the former prefixed to the hourly motion of the Moon in latitude, indicates that she is approaching, and the latter that she is receding from, the north pole of the ecliptic.

The letters M. A., m. a., denote Morning and Afternoon.

The Mahometan Era dates from the filight of Mahomet to Medina, July 16th, A. D. 662.

The Mahometan year is purely luñar; it consists of 12 synodical periods of the Moon, or of 354 days, 19 times in a cycle of 30 years, and 11 times of 355 days. The average length of this year is therefore 35438 days, which differs only thirty-three seconils from the truth ; a degree of exactness that only could have been attained by a long series of observations. But as no allowance is made for the excess of 11 days in the length of a tropical year over the time of 12 revolutions of the Moon, it is obvious that in about 33 years, the above months will correspond to every season and every part of the Gregorian year.

The unit of tude at any place, is the height at that place of that tide which arrives about a day and a half after the time of New or Full Moon, when the Sun and Moon at the moment of conjunction or opposition are at their mean distance from the Earth, and in the plane of the celestial equator.

This unit of altitude, which must be derived from observation for each place, multiplied by the quantities in the above table, gives the height of the spring tides at that place during the present year.

By the above table it appears, that the highest tides of 1845 will be those of February S, August 19, and September 17.

The actual rise of the tide, however, depends so much upon the strength and direction of the wind, that it not unfrequently happens that a tide, which would, independently of these, have been small, is higher than another, otherwise much greater. But when a tide, which arrives when the Sun and Moon are in a favorable position for producing a great elevation, is still further increased by a very strong wind, the rise of the water will be uncommonly great, sufficient perhaps to cause damage.

The formula, from which these tides were computed, is, however, strictly true only for Brest and its vicinity, and must be regarded as a very uncertain approximation for the coast of the United States.

The following table contains the Unit of Altitude of several ports and places on the coast of America, according to the best authorities.
