Eeduction of the Observations. — The method adopted in reducing the observations was, in all 

 essential respects, the .same as that exjilained in Prof. McLeod's report, in connection with the 

 difference of longitude between J\Iontrcal and Toronto. The equations of condition were weighted 

 when less than tive wires were observed by multiplying them by the following numbers : .956, .900, 

 .800, .633, according as the number of wires observed was 4, 3, 2 or 1.
