Clifton Hill, had been used for forming the base of the Fountain on the 
Steine, and another which had marked the boundary on the Dyke 
Road, had been carried away to form part of a fernery. A very large 
one used to stand in the Temple field, near Denmark Terrace, but it 
had probably been disposed of in the same way as a flint stone of 
prodigious size, that was once to be seen in Kemp Town—a hole 
having been dug into which it had been placed. 
Mr. ScorT, for the sake of eliciting Mr. Ward’s opinion, said he 
thought that possibly ice agency had something to do with the 
distribution of the Sarsen stones, seeing that erratic blocks had been 
carried some hundreds of miles by the same agency. He thought 
that Dr. Stevens had rather ignored this. 
Mr. WONFOR pointed out that the formations were known from 
which other erratic blocks came ; but there was no known formation 
from which the Sarsens could come. 
Mr. H. VERRALL pointed out several facts which militated 
against this theory; among others, there was no evidence of glacial 
action south of the Thames line. 
Mr. J. CLIFTON WARD, F.G.S., Geological Survey, remarked 
that where rocks were deposited by ice agency many different rocks 
were found ; but the greywethers were not mixed with other rocks. 
From a very close intimacy with ice-borne boulders, he felt pretty 
certain the Sarsens originated as Dr. Stevens had suggested. 
Dr. CoRFE asked if the stones of Stonehenge were not different 
from the greywethers? He had always understood so. 
Mr. G. ScoTr: Most of them are greywethers ; but some are 
not; these had been thought to be presentation stones,
