364 2. Now it is manifest of it self, in which of these years most died; but in which of them was the greatest Mortality of all Diseases in general, or of the Plague in particular, we discover thus. In the Years 1592, and 1636, we find the proportion of those dying of the Plague in the whole to be near alike, that is, about 10 to 23, or 11 to 25, or as about 2 to 5.

3. In the Year 1625, we find the Plague to bear unto the whole in proportion as 35 to 51, or 7 to 10, that is almost the triplicate of the former proportion; for the Cube of 7 being 343, and the Cube of 10 being 1000, the said 343 is not $1/5$ of 1000.

4. In Anno 1603, the proportion of the Plague to the whole was as 30 to 37, viz. as 4 to 5, which is yet greater than the last of 7 to 20 : For if the year 1625 had been as great a Plague year as 1603, there must have died not only 7 to 10, but 8 to 10, which in those great numbers makes a vast difference.

5. We must therefore conclude the year 1603 to have been the greatest Plague year of this Age.

6 Now to know in which of these four was the greatest Mortality at large, we reason thus: |48|

7. From whence it appears, That Anno 1636, the Christnings were about $2/5$ parts of the Burials: Anno 1592 but $1/3$; but in the year 1603, and 1625, not above an eighth: so that the said two years were the years of greatest Mortality. We said that the year 1603 was the greatest Plague year. And
