Dr. BARHAM read the following letter from Mr. Rogers of 
Penrose, accompanying his loan, for exhibition at this meeting, of 
a Hammer-head, of Greenstone, found in the parish of Cury :— 
: Penrose, Aug., 1872. 
Dear Dr. Barham, 
I send for your next Meeting of the Royal Institution of Cornwall, an 
unfinished hammer-head of greenstone, weight 1 lb. 122 ozs. avoirdupois, 
found last year on my estate of Burnow in Cury parish, a foot under surface, 
in a furze croft which was being broken for tillage. 
There is a small ancient earthwork near the centre of the estate, Oa. Ir. 
23p. in size; and the farm of Penvores, where the two-looped palstave* was 
found also last year, is not far off. 
The hammer-head is thus noticed by my friend Mr. Augustus W. Franks, 
keeper of antiquities in the British Museum: 
‘Your stone hammeér-head is rare for England. We generally consider 
‘such specimens as unfinished pierced axe-heads. Whether rightly or not, 
“Tam not certain. I have a very similar specimen here (Christy Collection) 
“from Denmark.” 
The Burnow specimen is precisely similar in form to a perfectly per- 
forated specimen in the British Museum, foundin the Thames, but apparently 
of rather more compact stone than this. It also has the same abrasion of 
one surface. 
See Photograph No. 16 of Pre-historic series of British Museum Photo- 
graphs. 1872. : 
Yours sincerely, 
JOHN J. ROGERS.
