 to Aleppo, and this it is: That keeping a particular account and memorial of the dayes of the departure and arrival of the Ships in the Ports of Alexandria, of Alexandretta, and this of Venice; in comparing sundry of them, which I did for my curiosity, I found that in exactness of account the returns hither, that is the voiages from East to West along the Mediterrane, are made in less time then the contrary courses by 25. in the Hundred: So that we see that one with another, the Eastern windes are stronger then the Western.

.I am very glad I know this particular, which doth not a little make for the confirmation of the Earths mobility. And although it may be alledged, That all the Water of the Mediterrane runs perpetually towards the Straits-mouth, as being to disimbogue into the Ocean, the waters of as many Rivers, as do discharge themselves into the same; I do not think that that current can be so great, as to be able of it self alone to make so notable a difference: which is also manifest by observing that the water in the Pharo of Sicily runneth back again no less towards the East, than it runneth forwards towards the West.

It hath been received by the Peripatetick Schools, that the Element of Fire, and also a great part of the Aire is carried about according to the Diurnal conversion from East to West, by the contact of the Concave of the Lunar Orb, as by the Vessel their container. Now without going out of your track, I will that we determine the Quantity of
