-- Note --
It should be noted in the treatment of this problem that the middle wire was assumed not to be the same as the mean of all the wires, as of course perfect construction of the reticule would demand.
The correction for the middle to the mean wire as found upon page 61 is only 0[superscript][?delta?][/superscript].019 a correction smaller than the probable error so that no correction in practical work can be made for this wire.
The mean and the middle wire may then be assumed as the same.
