others prostrate, the fruitful subject of monographs without 
number and still a mystery in its object, its erectors, its date, 
and its method of erection. Lithological knowledge has not even 
yet decided the nature of all its stones. The Sarsens of the 
exterior circle, and of the trilithons in the outer ellipse, of the 
Friar’s heel or gnomon, and three outlying stones, can easily be 
recognized, but the exact geological age of this stratum is doubtful, 
and also how in that distant and ignorant age such heavy masses 
could have been brought from the Marlborough downs, where the 
Sarsens of Avebury still stand, and the same stones called “ grey 
-wethers”” abound in the valleys. There is even more doubt of 
the nature and origin of the menhirs of the inner circle and 
ellipse, which are of igneous rocks, and not to be found nearer 
than S. David’s Head or Cornwall. Some are of syenite, green- 
stone and siliceous schist, and the guardian to this monument of 
Antiquity pointed out four stones, which are certainly not of 
either of these rocks, The so-called “ Altar Stone” is peculiar 
to itself, of micaceous sandstone, and standing on this horizontal 
slab at the summer solstice the sun is seen to rise at 3.44 a.m. 
__ exactly over the point of the gnomon. The Vice-President of the 

Club, the Rev. H. H. Winwood, standing on this stone, gave the 
_ Members an interesting dissertation on this abstruse structure, 
_ and related how on the first visit of the Field Club to Stonehenge, 
on June 24, 1867, he was present, and was most likely the sole 
survivor of that excursion. The Members slept at Amesbury on 
that occasion, and walked in the dark to await the rising of the 
sun, which he well remembered was observed most favourably, 
and seen from the Altar Stone through the eastern trilithon to 
stand exactly on the apex of the Friar’s heel. A most exhaustive 
series of papers is printed in the Wiltshire Archeological Magazine, 
vol, xvi., written by the late Mr. William Long, which mention 
all the writers of early date. on Stonehenge from Henry of 
Huntingdon’s Chronicle of the 12th Century to those of the 
present day, and attempt to define the motive of the erection
