dayes, at 25, 26, 26½; (the whole height of the smal Cyklindrick glass, whose cavity was about ⅛ of an inch diameter, being about 20. inches; besides a small Spherical bowl at the top, of about ¾ of an inch diameter; and a bowl at the bottom, which contained the liquor, of about 2 inches diameter: the space above the liquor being, at the first composure of it, voyd of Air, save what it had out of the liquor, which, being warm at the first putting in, fill'd the whole cavity, while the Glass was hermetically sealed.)

The Winter following, the liquor seem'd to remain much about the same temper as in the next foregoing. For in December, January, and February, we had at 14½ Frost certain; sometimes at 15. or higher; and the lowest, to which it did that winter descend, was 12¾. The height, in the following Summer, 1666, was usually about 19, 20, 21.; the highest of all, at 25.

About the end of December 1666, and the beginning of January following, it was, in hard frosty weather, at 12, 11., and once at 10½, the weather being very cold, and the liquor (it should seem) becoming some-what less spirituous, having evaporated some of its more subtil parts into the voyd cavity: and it was Frost certain, that winter, about 13½, (an inch lower than the years before,) some-times at 14, or 14½. The usual height, in Summer following, 1667, was about 19, 20, 21, and the highest at 24½.

The Winter-following, it-was scarce certain frost at 13.; but yet sometimes at 14, or a little higher: the lowest, to which it did descend that winter, (being very mild after Christmass,) was at 12. And the following Summer, 1668, usually about 18, 19, 20, the highest of all (the heat of that Summer being but very moderate,) at 22.

The next Winter it was frost certain, about 12½; but sometimes, at 13. or higher: the lowest of all, at 10¼. And in the Summer following, 1669, the highest of all (being but a cool Summer) not much above 20

But now this Christmas, 1669, though I find into be frost certain, about 12¼, and sometimes at higher than 13, yet hath it come some-times lower than 8; and particularly Decemb. 26in
