PORTO-SANTO, an island of the Atlantic Ocean, on the coast of Africa, and the least of those called the Madeiras. It is about 15 miles in circumference, and produces but little corn; however, there are oxen and wild hogs, and a vast number of rabbits. There are trees which produce the gum or rosin called dragon's blood; and there is likewise a little honey and wax, which are extremely good. It has no harbour, but good mooring in the road. It belongs to the Portuguese, and is 300 miles west of the coast of Africa. W. Long. 15. 5. N. Lat. 32. 30.
