Belonging to the same period of time as another
The population of India is the largest aggregate yet brought within the scope of a synchronous and uniform enumeration.
Copper would thus have been but seldom used unalloyed; and the relatively synchronous appearance of bronze in Europe, and the scanty "finds" of copper implements, are explained.
In another form devised by Callendar," a revolving contact disk is placed on the shaft of an alternator, or of a synchronous motor driven by the alternating current under test.
The first synchronous census of the colony, as it was then constituted, took place in 1865, on a fairly comprehensive schedule.
The most important innovation, however, was the transfer of the responsibility for filling up the schedule from the overseers to the householders, thereby rendering possible a synchronous record.
