MEMOIR OF CALEB B. HOSE. 
395 
observations recorded by Charles Babbage;* but the matter during 
the past sixty years has not attracted the attention it would seem 
to deserve. 
Rose’s careful lists of fossils, and his remarks on their geological 
and geographical distribution are most valuable, for he clearly 
recognised that succession of forms belonging to ditferent stages in 
the Chalk, that are now ranged into “ zones.” 
Coming to the “Diluvium,” lie remarked that “the boulders, 
so abundantly found in the clay, inclose organic remains which 
enable us to determine that their parent rocks are situated fifty, 
nay hundreds of miles apart from them. Without noticing the 
fragments of primitive rocks (which are more difficult to identify, 
in consequence of their not containing organic remains), I may 
particularise boulders from the old red sandstone , mountain 
limestone, alum-shale of Whitby, blue lias, cornhrash limestone , 
Septaria of the Oxford and Kimmeridge clags, &c., all inclosing 
oxuvire that indubitably determine from what strata they were 
disrupted.” llis descriptions of this mixed accumulation, which 
we now know to bo Glacial Drift, is exceedingly accurate ; but we 
cannot wonder that ho remarks (cautiously enough) that the facts 
“all combine to render it highly probable that the transport of 
these materials could not have been effected by any other agent 
than the Noachian Deluge.” An account of the organic remains of 
this Drift formed the subject of his earliest geological paper (1828) ; 
and he then maintained, from the absence of contemporaneous 
“marine testacea,” that the deluge must have been produced by 
freshwater. As he remarks in a letter to S. Woodward (1834): 
“ I cannot yet desert the Scriptural account of the Deluge.” 
Rose’s name will always be connected with the “ Brickearth of 
the Nar,” which he introduced to the attention of geologists. 
Arthur Young, in his ‘ Agricultural Survey of Xorfolk,’ had indeed 
described the shelly mud with oysters, as being used by farmers in 
the proportion of ten loads to an acre, as a good dressing for land. 
Rose collected and determined the fossils, and traced out the 
extent of the strata. His earliest account appeared in 1836, and 
he then recorded many of the species, including not only Mollusca,

quoted and enlarged upon by Be la Becke, ‘ Researches in Theoretical 
Geology/ 183-t, p. 98.
