PROFESSOR CLERK MAXWELL ON THE ELECTROMAGNETIC FIELD.

least squares to determine what further correction depending on the square of the velocity should be applied to make the outstanding errors a minimum.

The result of this examination showed that the calculated value of L should be multiplied by 1.0618 to obtain the value of L, which would give the most consistent results."

We have therefore L by calculation 430165 metres.
Probable value of L by method of least squares 456748 „
Result of rough experiment with the Electric Balance (see § 46) 410000 „

The value of L calculated from the dimensions of the coil is probably much more accurate than either of the other determinations.
