170 On the Meteors of 13th November, 1833. 
tic of 74 degrees, which is the inclination of the sun’s equator, as 
has been observed heretofore, respecting the zodiacal light. Gen. 
DeWitt observed the same at Albany, also, early in February, and 
describes it ‘ as extending towards, but not reaching Aldebaran.” 
Since this light was first observed by me on the Ist of December, 
it has advanced in the order of the signs through the constellations 
Sagittarius, Capricornus, Aquarius, Pisces, Aries and Taurus.* 
Let us now inquire whether its different positions will be such as 
the supposed comet would assume, as seen from the earth. 
The aphelion of the comet being in 21° of Taurus, we may esti- 
mate its true anomaly from that point at intervals of ten days during 
the whole period of its revolution, or 182! days, and we shall have 
the positions of the body in its orbit at each of these times. Compa- 
ring these with the corresponding positions of the earth, we shall de- 
termine the relative places of the comet and the sun. They will be 
as expressed in the following table.
