Product details 'Silex quartzum'
'Silex quartzum'
Eight specimens of flint pebbles, generally split or sectioned, from various locations including from near London and from Norwich in Norfolk. Plate 88 from British mineralogy: or coloured figures intended to elucidate the mineralogy of Great Britain, by James Sowerby, volume 1 (London, R.Taylor & Co., 1804). The accompanying text states that 'Flint pebbles, so universally known in the vicinity of London, are not so well known everywhere...The forms and colours of common flints are extremely various, and they give strong indications of being formed by infiltration and aggregation...They are often useful, as at Sandown Castle, near Deal, to defend the coast from the encroaching ocean.' The plate is inscribed: 'Augt. 1 1804. Published by Jas. Sowerby, London.'
Original: engraving. 1804
