6. That as there is no general Rule that admits not of some Exception, so there is in this Ocean a Tract of Sea wherein the Southerly and South-West Winds are perpetual, _viz._ all along the Coast of _Guinea_, for above five hundred Leagues together, from _Sierra Leona_ to the Isle of St. _Thomas_; for the South-East Trade Wind having pass'd the Line, and approaching the Coast of _Guinea_ within eighty or 100 Leagues, inclines towards the Shore, and becomes S. S. E. and by Degrees, as you come nearer, it veeres about to South, S. S. W. and in with the Land South-West, and sometimes West South-West; which Variation is better express'd in the Mapp hereto annexed, (_Vide Plate 2_) than it can well be in Words. These are the Winds which are observ'd on this Coast when it blows true, but there are frequent Calms, violent sudden Gusts call'd _Tornado's_, from all Points of the Compass, and sometimes unwholsome foggy Easterly Winds, call'd _Hermitaa_ by the Natives, which too often infest the Navigation of these parts. 7. That to the Northwards of the Line, between four and ten Degrees of Latitude, and between the Meridians of _Cape Virde_, and of the Eastermost Islands that bear that Name, there is a Tract of Sea wherein it were improper to say there is any Trade Wind, or yet a Variable; for it seems condemn'd to perpetual Calms, attended with terrible Thunder and Lightning, and Rains so frequent, that our Navigators from thence call this part of the Sea the _Rains_; the little Winds that are, be only some sudden uncertain Gusts, of very little Continuance and less Extent; so that sometimes each Hour you shall have a different Gale, which dies away into a Calm before another succeed, and in a Fleet of Ships in sight of one another, each shall have the Wind from a several Point of the Compass; with these weak _Breezes_ Ships are oblig'd to make the best of their way to the Southward through the aforesaid six Degrees, wherein 'tis reported some have been detain'd whole Months for want of Wind.
