the exad apparent time of the day, which, com-

fiiews how much either of them differ from apparent 
time; in this manner you find the hour of the 
day.

You firft move the plate K until the vernier on it 
cuts the 12 o’clock hour, and, difcharging the fcrew 
to which the declination handle is fixed, turn the 
telefcope down to the horizon, and obferve the point 
which is then in the middle of the field of the tele- 
fcope, or cut by the interfedlion of the crofs wires, 
and a fuppofed line drawn from the center of this 
field, to that point in the horizon, is your meridian 
line, where a mark may be fet up in order to pre- 
ferve itj you may likevvife preferve this line, by the 
azimuth circle, which being made moveable, fhould 
be turned fo as to bring the o of the azimuth plate 
to agree with its vernier, when the telefcope is point- 
ed to the meridian ; this motion in the azimuth plate 
will be found very convenient, fince you may thus 
recover the meridian line by it, and it will ihew the 
exadt azimuth of any objeft the telefcope is diredfed 
to, without diflurbing any other part of the inftru- 
ment : the beft time of the day for making this 
oblervation for finding your meridian, is about three 
hours before noon, or as much after noonj the meri- 
dian of the place may be found by this method very 
nearly, and, if proper allowance be made for re- 
fradtion,
