14. An example, to illustrate the method of computing by 
these theorems, may now be proper. 
Let it be required to compute A and B by the 1st and 3d 
theorems, in Art. 12. when the two planets are Venus and the 
Earth. 
This arithmetical work may stand as follows, in three co- 
lumns, the logarithms being in the middle, and the numbers 
corresponding to them on the two sides ; where a distinction 
is made, which is too obvious to need any description. By this 
arrangement, a frequent repetition of words, number, and lo- 
garithm, will be avoided.

* AH these constant logarithms are to be written on a slip of paper, for the sake of 
expedition in the use of them.
