IV. Longitudes and approximate Latitudes of the Moon, at Paris
midnight commencing the civil day.

(3.) 2005 b.c, April 8, Long. 357° 4' 56", Lat. 59' South, increasing.
(4.) 506 b.c, Mar. 27, Long. 342° 37' 49", Lat. 58' North, increasing.
(5.) 1652 b.c., April 21, Long. 194° 49'39", Lat, 1° 33'North, increasing.

To the Sun's longitude in No. (1) I have added 7', and to that
in No. (2) I have added 13', as a rough allowance from midnight at
Paris to sunrise at Thebes: and from the altered places I get the
following:—

V. Sun's r.a. and n.p.d. at sunrise.

(1.) 1322 b.c., July 20, r.a. 6h 58m 55s, n.p.d. 66° 47' 32".
(2.) 1985 b.c, Jan. 2, r.a. 17h 41m Is, n.p.d. 113° 55' 43".

VI. With these, and the star-places above, and the latitude of
Thebes 25° 44/ North, the following times of rising are com-
puted—
