P.S.I do not accompany this public letter with a private note to Dr.
Priestly, because communications of that nature carry an appearance of bravado, which, even in exercising the right of a necessary defence, appear to me imcompatible with decency and politeness.
THE ZODIACAL SIGNS AND CONSTELLATIONS.
(Compiled by the publisher from recognized authorities.) The Zodiac is an imaginary girdle or belt in the celestial sphere, which extends about eight degrees on each side of the Ecliptic.

It is divided into twelve portions, called the signs of the Zodiac, within which all the planets make their revolutions.

The Zodiac is so called from the animals represented upon it, and is supposed to have originated in remote ages and in latitudes where the camel and elephant were comparatively unknown.

This pictorial representation of the zodiac was probably the origin, as M.Dupuis suggests, of the Arabian and Egyptian adoration of animals and birds, and has led in the natural progress of events to the adoration of images by both Christians and pagans.
"The Signs of the Zodiac, (says Godfrey Higgins in The Anacalypsis) with the exception of the Scorpion, which was exchanged by Dan for the Eagle, were carried by the different tribes of the Israelites on their standards; and Taurus, Leo, Aquarius, and Scorpio or the Eagle--the four signs of Reuben, Judah, Ephriam, and Dan--were placed at the four corners, (the four cardinal points), of their encampment, evidently in allusion to the cardinal points of the sphere, the equinoxes and solstices, when the equinox was in Taurus.

(See Parkhurst's Lexicon.) These coincidences prove that this religious system had its origin before the bull ceased to be an equinoctial sign, and prove also, that the religion of Moses was originally the same in its secret mysteries as that of the Heathen, or, if my reader likes it better, that the Heathen secret mysteries were the same as those of Moses." The Ecliptic, a great circle of the sphere, (shown on the preceding map by two parallel lines), is supposed to be drawn through the middle of the Zodiac, cutting the Equator at two points, (called the Equinoctial points), at an angle with the equinoctial of 23 degrees 28 minutes, (the sun's greatest declination), and is the path which the earth is supposed to describe amidst the fixed stars in performing its annual circuit around the sun.
