out of the strata in oiir cliffs, seems to indicate that since this deposit took plsee I 
there can have been no violent disturbance in this strata. The coincidence of af 
having found the same remains, especially the crocodile, in a group in the saoe I 
strata, and at the^ same height or thereabouts from high*waier mark on both couS, 
strikes one as indicadve of the space occupied by the freshwater lake orriTff.u the 
time of their deposit, being nearly similar, or equivalent to that now occupwdh

Oh J}elrilus derived from the London Clay and deposited ifl the Red Craj. 
By the Rev. J. S. Henslow. 
Peculiar nodules in the red crag at Felixtow in Suffolk had been fermeriy Co#- 
aideretl by the author to be of coprolitic origin ; hut it bad since been sstbfactorilf 
shown lliat they were detrital routerials from the London clay. Xodules contakiiij 
^ j cent, of phosphate of lime occur in great abundance at Coldifsttria 
the London clay j and those in the crag are only nodules of this deieriptioadightlj 
roiled and somewhat modified by having had a poitioo of iron pyrites courwOTto 
oxide of iron. Itwai the author's object to show also that the Cewtolites ducriW 
by Professor Owen, numerous fragments of bones, and nvany highly mioeralijsd fMflb 
ottnd in the cra^ must be classed as detrital materials from the London clay. Rt 
genuine crag fossils are readily separable from those of the eocene period ky dnif 
out being mmeralized ; and such is the case with fish'bonea, crustacean and otieffe* 
n^na, as well as with the testacean shells, so abundant and well-known in the eng. 
There are hollow nodules of oxide of iron in the same beds, with other detntsl 
ni^itenus; audit was considered that these had been derived from decomposed nodulB 
of aulnhuret of iron, so common in the London clay. The materials which hsdbr' 
ntshed the phosphate of lime to the nodules first noticed appear to hare been derirw 
from decomposed bones, teeth, and crustaceans.
