at St. Winnow ; and in the near neighbourhood of these barrows 

 had been found gold ornaments. He was desirous to mention this, 

 in order that persons might not be discouraged by the want of 

 immediate success in the examination of these barrows near 

 Truro. 



Stonehenge. There was exhibited, from Mr. Whitley (one 

 of the Secretaries of the Institution), a plan of Stonehenge, with 

 its encircling bank and ditch, and its avenue. In the explanation 

 accompanying the plan, Mr. Whitley stated that it was made by 

 him for the purpose of testing the statement that a line from the 

 altar-stone over the " Friar's Heel," through the middle of the 

 Avenue, was in the direction of the sun at its rising on the longest 

 day. The bearing or angle of this line with the True North was 

 determined mth great exactness ; and the Sun's true amplitude, 

 when he is about one of his diameters above the horizon, was 

 shown to be, on the 21st of June, very nearly in the direction 

 of a line from the altar over the Friar's Heel ; so that, looking 

 from the altar-stone, a line through the entrance to the Temple, 

 over the " Slaughtermg-stone " and the " Friar's Heel," would be 

 exactly in the direction of the Sun when on the horizon on the 

 longest day. It was therefore probable that this Temple had 

 some relation to worship of the Sun. — Mr. Whitley added, that 

 the outer circle of the Temple had consisted of 30 stones, placed 

 upright. The inner circle is of unhewn sUones — some of granite, 

 probably from Dartmoor ; but many of hornblende rock, like that 

 of the Lizard. The large stones are of tertiary sandstone, the 

 *' Sarsen Stones " of the Chalk Downs. Many of the barrows 

 have a ditch around each, from which the earth was taken for 

 their formation ; and in some places there are t\vin barrows, the 

 ditch surrounding the two. All the barrows, and also the ad- 

 jacent camps, were formed in the same manner, by removal of soil 

 from a surrounding ditch ; indicating that they were made by 

 the same people. The Hill-Castles in Cornwall shew the same 

 mode of construction.
