CHAP. VI. Of the Sickliness, Healthfulness, and Fruitfulness of Seasons.

1. HAving spoken of Casualties, we come next to compare the sickliness, healthfulness, and fruitfulness of the several Years, and Seasons, one with another. And first, having in the Chapters afore∣going mentioned the several years of Plague, we shall next present the several other sickly years; we meaning by a sickly Year, such wherein the Burials exceed those, both of the precedent, and subsequent years, and not above 200 dying of the Plague, for such we call Plague-Years; and this we do, that the World may see, by what spaces, and intervals we may hereafter expect such times again. Now, we may not call that a more sickly year, wherein more die, because such excess of Burials may proceed from increase, and access of People to the City onely.

Page  40 2. Such sickly years were 1618, 20, 23, 24, 1632, 33, 34, 1649, 52, 54, 56, 58, 61, as may be seen by the Tables.

3. In reference to this Observation, we shall pre∣sent another, namely, That the more sickly the years are, the less fecund, or fruitfull of Children also they be, which will appear, if the number of Chil∣dren born in the said sickly years be less, then that of the years both next preceding, and next following; all which, upon view of the Tables, will be found true, except in a very few Cases, where sometimes the precedent, and sometimes the subsequent years vary a little, but never both together. Moreover, for the confirmation of this Truth, we present you the year 1660, where the Burials were fewer then in either of the two next precedent years by 2000, and fewer then in the subsequent by above 4000. And withall, the number of Christnings in the said year 1660 was far greater then in any of the three years next afore∣going.

4. As to this year 1660, although we would not be thought Superstitious, yet is it not to be neglected, that in the said year was the King's Restauration to his Empire over these three Nations, as if God Almigh∣ty had caused the healthfulness and fruitfulness there∣of to repair the Bloodshed, and Clamities suffered in his absence. I say, this conceit doth abundantly counter∣poise the Opinion of those who think great Plagues come in with Kings reigns, because it hapned so twice, viz. Anno 1603, and 1625, whereas as well the year 1648, wherein the present King commenced his right to reign, as also the year 1660, wherein he commenced Page  41 the exercise of the same, were both eminently health¦full, which clears both Monarchie, and our present King's Familie from what seditious men have surmised against them.

5. The Diseases, which beside the Plague make years unhealthfull in this City, are Spotted Feavers, Small Pox, Dysentery, called by some The Plague in the Guts, and the unhealthfull Season is the Autumn.
