MEMOIR OF CALEB B. ROSE. 
sphere of professional labour, while the work of his leisure hours 
brought him into correspondence with many of the leading geologists 
and microscopists of his day. 
In 1859 Eose retired from practice and went to reside at 
25 King Street, Great Yarmouth, where he passed the remainder 
of his days. Here he continued his geological observations, and 
they afforded him ample scope and solace after his busy professional 
career. In October, of the same year, he accompanied John Gunn, 
Prof. Prestwich, and Sir John Evans on a visit to Iloxne ; and he 
again visited the locality in the following autumn. He records 
the finding, by the Eev. S. \V. King, of two Celts or Hint- 
implements : one in brickearth four feet from the surface, the other 
from gravelly shingle between the brickearth and the lluviatile 
bed that underlies it.* 
Eose paid some attention to the Glacial Drifts near Yarmouth, 
and ventured to doubt the occurrence of a lower Boulder Clay, 
speaking of the “ Lower Drift ” that occurs beneath the [Chalky] 
Boulder Clay, as a ferruginous loam with sands and gravels, while 
he employed the term Upper Drift for the gravels, &c. that overlie 
the Boulder Clay.t He refers also in one of his papers (1859) to 
a “drifted mass of chalk lying upon the Kimmeridge Clay in a pit 
at Ely.” ]; This statement is interesting, as some controversy 
subsequently arose on the mode of occurrence of the Chalk at this 
locality : and the rock was eventually proved to be a Boulder. 
In 1860 he drew the attention of John Gunn and Professor 
Prestwich to the deep boring at Bacon’s Brewery at Yarmouth, 
whereby the presence of the London Clay and Woolwich and 
Heading series was for the first time notified in Norfolk. || Eose 
himself has given some account of the boring, § and notes the 
presence of ten feet of Crag above the London Clay. The occurrence 
of Crag has always been a doubtful matter. Eose recorded the 
occurrence of B alarms, Mytilus edulis, and Tellina balthica. §
