174 ASTRONOMY. 
104. With the help of a celestial glose, the same end may be attained 
more readily, by setting up the sphere for the place of observation, as also 
for the day and hour of observation. It is then only necessary to look in 
what direction and at what elevation above the horizon any star is found on 
the globe, and then direct the eye towards the corresponding part of the 
heavens, to be able to identify them on both spheres. In this way, for 
instance, it might be observed by means of the celestial globe, that at 73 
o’clock of Jan. 18, a star of the first magnitude, Capella, stands a little to the 
south-east of zenith, outside of the milky way. It is then only necessary at 
that time to look a little to the south-east, out of the milky way, actually to 
see Capella. 
105. Knowing the twelve constellations of the zodiac, it will not be diffi- 
cult to find the visible planets, Mercury, Venus, Mars, Jupiter, Saturn, and 
even Uranus, in these constellations, distinguishing them with certainty from 
the fixed stars by their peculiar appearance and their varying position with ° 
respect to the neighboring stars.
