[645] This is mentioned by Ovid, Met. xv. 273, 274.

[646] This is again referred to by our author, vi. 31; also by Strabo, and by Seneca, Nat. Quæst. iii. 26.

[648] The river here referred to is the Tanager, the modern Rio Negro. See the remarks of Hardouin and Alexandre in Lemaire, i. 439.

[649] From a note in Poinsinet, i. 302, we learn that there has been some doubt respecting the locality of this river. It is mentioned by Virgil, Æn. i. 244, and it forms the subject of Heyne’s 7th Excursus, ii. 124 et seq. Virgil also speaks of the Timavus, Ec. viii. 6; and Heyne, in a note, gives the following description of it: “Timavus in ora Adriæ, non longe ab Aquileia fluvius ex terra novem fontibus seu capitibus progressus, brevi cursu, in unum alveum collectus, lato altoque flumine in mare exit.” i. 127, 128.

[650] This remark is not to be taken in its full extent; the water of these lakes contains a large quantity of saline and other substances dissolved in it, and, consequently, has its specific gravity so much increased, that various substances float on it which sink in pure water.

[651] According to Hardouin, this is now called the Lake of Andoria, near the town of Casalnuovo; Lemaire, i. 439. Poinsinet calls it Anduria, i. 303.

[652] The petrifying quality of this river is referred to by Ovid, Met. xv. 313, 314; Seneca quotes these lines when treating on this subject, Nat. Quæst. iii. 20.

[653] Aristotle, Strabo, and Silius Italicus, viii. 582, 583, refer to this property of the Silarus; but, according to Brotier, it does not appear to be known to the present inhabitants of the district through which it flows. Lemaire, i. 440.

[654] In a subsequent part of the work, xxxi. 8, our author remarks, “Reatinis tantum paludibus ungulas jumentorum indurari.” We may presume that the water contained some saline, earthy or metallic substance, either in solution, or in a state of minute division, which would produce these effects. It does not appear that anything of this kind has been observed by the moderns in this water.
