MEMOIR OF CALEB B. ROSE. 
It was not until 1835 — 36 that Eose published his most important 
paper, £ A Sketch of the Geology of West Norfolk,’ which contained 
tire results of his observations made during the previous seventeen 
years. Geologists at the present day are hardly content to wait so 
long a time before recording their facts and conclusions ; the 
consequence is that, while more pi’olific in producing papers, the 
results appear often in an attenuated form, and lack the sterling 
value of some of the earlier and more matured pieces of work. 
Eose tells us that in arranging and publishing his geological 
notes, he but responded to an appeal made by Dr. Fitton, from the 
chair of the Geological Society at the Annual General Meeting 
of the Fellows in 1828, in the following words : 
“ But those who are deprived of the privilege of travelling even in 
England, must not suppose that they can be of no service as geologists : or 
if they belong to our bod}', that they are thus released from their obligation 
to be active in our cause: and there are two descriptions of persons, — the 
resident clergy, and members of the medical profession in the country, — to 
whom what I am about to saj r may be more particularly deserving of 
attention. Such persons, if the}' have not yet acquired a taste for natural 
science, can hardly conceive the interest which the face of the country in 
their vicinity would gain, however unpromising it may appear, by their 
having such inquiries before them; how much the monotony of life in 
a remote or thinly inhabited district would thus be relieved; nor how much 
benefit they might confer on the natural history of their country.” 
It is interesting to note that Fitton appeals to the clergy, for, as 
previously remarked, their attitude was often opposed to scientific 
inquiry. He, however, had admirable examples in Buckland, 
Conybeare, and Sedgwick; while in Norfolk, John Gunn, James 
Layton, and others devoted themselves in a humbler way to the 
search after truth. 
In his paper on West Norfolk, Eose took as the eastern limit of 
His observations a line drawn from W ells to Thetford. Commencing 
with an account of the oldest strata, he shows how difficult it is to 
fix a plane of division between the Oxford and Kimmeridge Clays, 
on account of the local absence of the “Coral rag beds.” His 
careful record of facts, and the fossils which he determined, enable 
us, however, to identify the horizon of the Corallian beds at Denver 
Sluice, and in a deep well-sinking at Lynn ; for the recent observa- 
tions of Thomas Eoberts in Cambridgeshire and Lincolnshire, show 
that the “Coral rag,” or Corallian beds, as they arc now called, are.
