- To find the Altitude of a star when passing
the Meridian -
- Add together the Co latitude of the place and the
declination when they are of the same names
- or take their difference when they are of contrary names.
- The Altitude to be reckoned from the South when the
latitude is North and from the North when the
latitude is South - but when the sum exceeds
90degrees it is to be taken from 180degrees and reckoned
from the opposite point of the horizon -
- When the compliment of the Stars declination is less than
the latitude of the same name it will not rise
or set but pass the Meridian below the poles
11 H. 58 M. 0 S after it has passed the Meridian above
the pole and the latitude may thence be found
by rules laid down in page 189. (Norie) -
- The meridian on least altitude at that time
is found by subtracting the compliment of the
declination from the latitude which Altitude is
to be reckoned from the North or South according
to the latitude. -
