The lakes which receive no rivers, and from which no rivers issue, are greater in number than those just spoken of; these lakes are kinds of pools where the rain water collects; or may proceed from subterraneous waters, which issue in form of springs, in low places, where they cannot afterwards find any drain. The rivers which overflow may likewise leave stagnate waters in the country, which may remain for a long time, and only be replenished by other inundations. The sea has often inundated lands and formed saline lakes therein, like that at Haarlem, and many others in Holland, to which, no other origin can be attributed; or by losing its natural motion, might quit some land, and leaving water in the lowest places may have formed lakes, which have continued to be supported by rains. In Europe there are many small lakes of this kind, as in Ireland, Jutland, Italy, in the country of the Grisons, Poland, Muscovy, Finland, and in Greece. But all these lakes are very inconsiderable. In Asia there is one near the Euphrates, in the desert of Irac, more than 15 leagues long: another in Persia nearly of the same extent, and on which the towns of Kelat, Tetuan, Vastan, and Van, are situated; another small one in Chorazan near Ferrior; another in Independent Tartary, called Lake Levi; two in Muscovy Tartary, another in Cochinchina, and one in China very large, and not far distant from Nankin; this last, nevertheless, communicates with the adjacent sea, by a canal several leagues in length. In Africa there is a small lake of the same kind in the kingdom of Morocco; another near Alexandria, which appears to have been left by the sea; another very considerable one formed by the rain in the desert Azarad, about the 30th degree latitude; this lake is eight or ten leagues long; another still larger on which the town of Gaoga is situate, in the 27th degree; another much smaller, near the town of Kanum, under the 30th degree; one near the mouth of the river Gambia; many more in Congo, about the 2d or 3d degree of south latitude; two more in the country of the Caffrees, one called the Lake Rufumbo, of no great length, and another in the province of Arbuta, which is perhaps the greatest lake of this kind, being about 25 leagues in length by seven or eight in breadth; there is also one of these lakes at Madagascar, near the east side, about the 29th degree of south latitude.
