inches in length, and three-fourths of them are shed horns, in- 
dicating that they are at present not far removed from their original 
locality, and confirm at the same time the tradition that this part 
of the sea, called the Holmes, was originally a Forest.” It is 
interesting also to note here that, judging from a pencil drawing 
preserved among his papers, he was evidently aware of the 
peculiarity of the double curvature of the tusk of the mammoth, 
which was supposed not to have been noticed until 18G4.'"' 
Later on (23rd March, 1820) in another communication to Dr. 
Fitton, ho added : “ In putting my notes together of the different 
sections of the crag strata, I was struck with the regular occurrence 
of nodular flints reposing on the chalk. Wherever a section has been 
made in tho crag strata of Norwich, with one exception, tliero 
lias been found a layer of these flints, from twelve to eighteen 
inches in thickness, reposing on the chalk ; reasoning from analogy 
wo should say that the chalk in these instances had been subject to 
tho action of currents of water previous to the deposition of the 
shells ; as the appearance of the flints perfectly agrees with the 
like phenomena going on at Foulness point, Cromer, and at Trim- 
mingliam beach on our coast ; at tho latter place they are by no 
means so numerous, which may bo accounted for from the im- 
mature state of the flints in the chalk at that place. The chalk 
under these flints is perforated as if by pholades.” f 
This year (April, 1829) he submitted to his friend Mr. Amyot 
somo “ Fragments illustrating the History of Norwich Castle,” in 
which he pointed out the resemblance of its ornaments to those of 
Saxon date ; thus agreeing with other writers that the building 
was erected before the Conquest. J In May he communicated some 
“ Observations on the Found Towers of Norfolk,” to the Society 
of Antiquaries. Having traced out their distribution on a map, 
he found that they were not peculiar to the lino of British track- 
ways, and were more frequent in those parts of Norfolk where

t These notes were not published at the time, though the substance of 
them is given later on in his Geology of Norfolk. This explanation is the 
same as that independently arrived at by Mr. Ilarmer, aud published about 
two years ago. Quart. Journ. Geol. Soc., Yol. xxxiii., p. 134.
