But it is important that the observations should be closely compared with one and the same definite system of elements; and, as by leaving out decimals nothing would be gained in point of convenience in computing, there was no reason for altering in any respect the elements given by calculation.

The expression for , developed according to the above numbers, is as follows: for the sake of brevity stands for , and for .



We may here add the completely developed expressions for the three components of the magnetic force.
