at the boundary between the two kingdoms. It is between the river Halys, and 

 the river Melas, on which was the ancient city Melitene. The river Melas runs 

 eastward into the Euphrates. At half an hour after 12, the shade entered on the 

 Caspian sea, and at 1 on the Kalmuc Tartary. 



We see here an authentic parapegma in ancient history, deduced from astro- 

 nomy : and we see a remarkable instance of a most furious war terminated by 

 the intervention of an eclipse. 



XXXIV. A further Account of the Giants' Causeway in the County of Antrim 

 in Ireland. By the Rev. Richard Pocock, LL.D., F.R.S. p. 226. 



Dr. P. having taken another, and more particular view of the country about 

 the causeway, states that he went about 2 miles to a peninsula called Donseverik, 

 where he saw some tendency in the rock towards this work of nature ; and going 

 about half a mile farther, came to the beginning of the pillars in the sea cliff, 

 about 5 miles from the causeway : and the shore and cliffs being shaped mostly 

 in little semicircular bays, he had many beautiful views of the upper and middle 

 strata of pillars : in one particularly they had much the appearance of ruined 

 porticos one over the other ; and turning the little end of a spy-glass, it appeared 

 something like the ruins of Palmyra, as a view of them is represented in a copper- 

 plate, published in the Philosophical Transactions. This wonderful work of 

 nature is continued on in the cliffs for about a quarter of a mile beyond the 

 Giants' Causeway. 



He saw it again in the road to Coleraine, 5 miles to the west of the Cause- 

 way, in a low hill a furlong to the south of the road, and 2 miles to the south 

 of the sea. The pillars here are small ; and being about a mile and a half from 

 Ballimagarry, where the earl of Antrim has a ruined house, lately burnt down 

 it served as a quarry for building part of that house, in which he saw a great 

 number of the stones, and particularly one of Q sides. He saw others near 2 

 miles farther, to the south of the road in a low hill, within 2 miles of Coleraine; 

 so that the whole extends about 1 1 Irish miles, or 14 English. 



Beyond Coleraine, to the east of Magilligan, he saw in the rocks towards the 

 sea-cliffs, the stones in the hills very regular, appearing at a distance much like 

 these pillars. This is 6 computed miles beyond Coleraine, and consequently 

 about 10 English miles from the last pillars. At Fairhead also, a high point of 

 land, 3 miles to the east of Ballycastle, towards the top of it, the rock appears 

 as in grand pillars. They say it is not in joints, but it has something of the ap- 

 pearance of a grand Gothic piece of workmanship. It is a black stone, weighty 

 and brittle : and he had been informed, that it was tried in a glass-house, and 

 that it melted with kelp, so as to make the black glass bottles : which experiment 

 he was told had been made by Mr. Dobbs.
