* This expression was added to leave Liberty for a further inquiry, whether the Experiment, which hereby appears convincing as to the main thing intended to be proved may not admit the having something further debated, and annext about some circumstantial thing or other.it weighs very near * or altogether as much in Water, as the self same portion of liquor would weigh in the Air.

The same day we repeated the Experiment with another sealed Bubble, larger then the former (being as big as a great Hen-egg,) and having broken this under water, it grew heavier by 7. drachms and 34. graines; and having taken out the Bub1e, and driven our the water into a counterpois'd Glass, we found the transvasated liquor to amount to the same weight, abating 6 or 7 graines, which it might well have lost upon such acccompts, as have been newly mentioned.

FRom England to Cape Finis Terræ in Gallicia in 44. degr. North Lat. the Winds are as variable as with Vs; onely the Bay of Biscay is more subject to storms, and the Sea more rough, and the Waves running very high.

From thence to 34. degr. The Wind is variable also, but if you be within 100 leagues of the European Continent, it is generally inclined to North-East

From 34 degrees, if you be inclining to the coast of Africa, or about the Meridian of the Canaries, the Wind is so certain, and constantly at North-East (or within two points) that it is rare to find it otherwise. Yet in Winter, upon the coast of Africa there are sometimes Westerly storms, that are violent, but of no long continuance. And in Summer, when it is sometimes calme, the Air will come variably. These North-East-Winds hold most commonly to 8. degrees North-Latitude, and then begin the Tornado Winds, which are most part confined between 8. and 4. degrees North-Latitude. They are sel-
