In their passage through the press I have, however, had many opportunities to consult and refer to Mr. Thirlwall's able and careful work.
 The passage in Aristotle (Meteorol., l. I, c. 14), in which, speaking of the ancient Hellas (the country about Dodona and the river Achelous), the author says it was inhabited by a people (along with the Helli, or Selli) then called Graeci, now Hellenes (tote men Graikoi, nun de Hellaenes) is well known. The Greek chronicle on the Arundel marbles asserts, that the Greeks were called Graeci before they were called Hellenes; in fact, Graeci was most probably once a name for the Pelasgi, or for a powerful, perhaps predominant, tribe of the Pelasgi widely extended along the western coast - by them the name was borne into Italy, and (used indiscriminately with that of Pelasgi) gave the Latin appellation to the Hellenic or Grecian people.
 Modern travellers, in their eloquent lamentations over the now niggard waters of these immortal streams, appear to forget that Strabo expressly informs us that the Cephisus flowed in the manner of a torrent, and failed altogether in the summer. "Much the same," he adds, "was the Ilissus." A deficiency of water was always a principal grievance in Attica, as we may learn from the laws of Solon relative to wells.

 According to some they were from India, to others from Egypt, to others again from Phoenicia. They have been systematized into Bactrians, and Scythians, and Philistines - into Goths, and into Celts; and tracked by investigations as ingenious as they are futile, beyond the banks of the Danube to their settlements in the Peloponnese. No erudition and no speculation can, however, succeed in proving their existence in any part of the world prior to their appearance in Greece.

 All those words (in the Latin) which make the foundation of a language, expressive of the wants or simple relations of life, are almost literally Greek - such as pater, frater, aratrum, bos, ager, etc. For the derivation of the Latin from the Aeolic dialect of Greece, see "Scheid's Prolegomena to Lennep's Etymologicon Linguae Grecae."
 The Leleges, Dryopes, and most of the other hordes prevalent in Greece, with the Pelasgi, I consider, with Mr. Clinton, but as tribes belonging to the great Pelasgic family. One tribe would evidently become more civilized than the rest, in proportion to the social state of the lands through which it migrated - its reception of strangers from the more advanced East - or according as the circumstances of the soil in which it fixed its abode stimulated it to industry, or forced it to invention. The tradition relative to Pelasgus, that while it asserts him to have been the first that dwelt in Arcadia, declares also that he first taught men to build huts, wear garments of skins, and exchange the yet less nutritious food of herbs and roots for the sweet and palatable acorns of the "fagus," justly puzzled Pausanias. Such traditions, if they prove any thing, which I more than doubt, tend to prove that the tribe personified by the word "Pelasgus," migrated into that very Arcadia alleged to have been their aboriginal home, and taught their own rude arts to the yet less cultivated population they found there.
 See Isaiah xxiii.
 The received account of the agricultural skill of the Pelasgi is tolerably well supported. Dionysius tells us that the Aboriginals having assigned to those Pelasgi, whom the oracle sent from Dodona into Italy, the marshy and unprofitable land called Velia, they soon drained the fen: - their love of husbandry contributed, no doubt, to form the peculiar character of their civilization and religion.
 Solinus and Pliny state that the Pelasgi first brought letters into Italy. Long the leading race of Italy, their power declined, according to Dionysius, two generations before the Trojan war.
 Paus. Arcad., c. xxxviii. In a previous chapter (II.) that accomplished antiquary observes, that it appeared to him that Cecrops and Lycaon (son of Pelasgus and founder of Lycosura) were contemporaries. By the strong and exaggerating expression of Pausanias quoted in the text, we must suppose, not that he considered Lycosura the first town of the earth, but the first walled and fortified city. The sons of Lycaon were great builders of cities, and in their time rapid strides in civilization appear by tradition to have been made in the Peloponnesus. The Pelasgic architecture is often confounded with the Cyclopean. The Pelasgic masonry is polygonal, each stone fitting into the other without cement; that called the Cyclopean, and described by Pausanias, is utterly different, being composed by immense blocks of stone, with small pebbles inserted in the interstices. (See Gell's Topography of Rome and its Vicinity.) By some antiquaries, who have not made the mistake of confounding these distinct orders of architecture, the Cyclopean has been deemed more ancient than the Pelasgic, - but this also is an error. Lycosura was walled by the Pelasgians between four and five centuries prior to the introduction of the Cyclopean masonry - in the building of the city of Tiryns. Sir William Gell maintains the possibility of tracing the walls of Lycosura near the place now called Surias To Kastro.
 The expulsion of the Hyksos, which was not accomplished by one sudden, but by repeated revolutions, caused many migrations; among others, according to the Egyptians, that of Danaus.
