These Tables were computed by the following rule; viz., To the constant log. 0. 978604,* add the log. co-sines of the latitude and the declination ; the sum, rejecting 20 from the index, will be the log. of a natural number, which, being subtracted from the natural co-sine of the difference between the latitude and the declination, when they are...
