The decennium extending from 1550 to 1560 was the good period of Ivan IV.'s reign, when he deliberately broke away from his disreputable past and surrounded himself with good men of lowly origin.
The greater part of this is debitable, as just pointed out, to the first year, in which the mortality, calculated upon the number of births, ranged, in the decennium 1895-1904, between 70 per mille, in the exceptionally favourable circumstances of the Australasian States, to nearly 270 in European Russia.
The succeeding decennium is the culminating period of Scottish Presbyterianism, when, having successfully resisted the crown, it not only was supreme in Scotland but exercised a decisive influence over England.
In the United States the rate of increase per decade was as follows: In England and Wales the rural population increased in the aggregate during the first half of the 19th century, but at a gradually diminishing rate; in the second half of the century the population declined with varying regularity, until the decennium 1891-1900, when there was an increase.
