Dear Mr Darwin,

Mr Codrington’s paper is on the “Superficial deposits of the South of Hampshire and the Isle of Wight” and is published in the Quarterly Journal of the Geological Society Vol. XXVI P. 528.¹ It is one of the most admirable descriptions of the gravels I have seen—

I visited the cutting on the railway near here this afternoon and found that more than three fourths of the pebbles are broken— Some action, violent I think, has cleared them from off the hills above 400 feet above the sea and spread them out in wide sheets below 200 feet—

Mr Farrer has given me some most interesting information respecting the absence of flints over the surface of the greensand in the neighbourhood of Abinger and I am much elated to find it fits in beautifully with my glacial theory—²

Yours very truly | Thomas Belt
