In the figures of plates 3 and 5, the letters _n.f._, _n.p._, &c., are affixed to the proper quadrants.

It is to be remembered that the quadrants thus indicated are measured either way from the point and feather of the diametral arrows.
Next, of the apparent annual motion of the stars.

This takes place in exactly the same manner as the daily motion.

If we view the sky at eight o'clock on any day, and again at the same hour one month later, we shall find that at the latter observation (as compared with the former) the heavens appear to have rotated by the _twelfth part_ of a complete circumference, and the appearance presented is precisely the same as we should have observed had we waited for two hours (the _twelfth part_ of a day) on the day of the first observation.
* * * * * Our survey of the heavens is supposed to be commenced during the first quarter of the year, at ten o'clock on the 20th of January, or at nine on the 5th of February, or at eight on the 19th of February, or at seven on the 6th of March, or at hours intermediate to these on intermediate days.
We look first for the Great Bear towards the north-east, as already described, and thence find the Pole-star; turning towards which we see, towards the right and downwards, the two guardians of the pole ([beta] and [gamma] Ursae Minoris).

Immediately under the Pole-star is the Dragon's Head, a conspicuous diamond of stars.
