A RH^TIC SECTION AT REDLAND. 
the name of " New Clifton," and a low hill, on which Cold- 
harbour Farm stands, has been cut through for the main 
road, exposing Lower Lias, Rhsetic, and Upper Trias beds. 
Owing to small anticlinals, which give a somewhat wavy 
appearance to the section, the dij) is not very easy to 
determine, but it may be reckoned at some 2° or 3° N. 60° E. 
The cutting is about 5 to 7 feet in depth ; but being on a 
slope, by measuring at various points the section shown 
opposite has been obtained. 
The Black Shales probably continue downwards for 
another 4 feet or 5 feet ; but although the Tea-green and 
Red Marls crop out a short distance away, the junction is 
not exposed. 
Of the sections previously recorded, that of Pylle Hill ^ so 
nearly resembles the above that the marginal letters used 
by Edward Wilson have been added for purposes of com- 
parison. Owing to the thinning out of some beds, also to 
changes in composition of others, this co-relation is in a 
few cases only approximate. Pylle Hill shows 17 feet of 
Rhsetics. This section (allowing for 5 feet unexposed) gives 
only about 14 feet, the priucipal loss occurring in bed " M," 
which measures 4 feet 11 inches in E. Wilson's section. 
Many of the beds are of the usual character, and require 
no special comment, but bed K " is very fossiliferous, 
being in some horizons full of the pretty little water plant 
known as Naiaditps acuminatus. This plant has been 
found at other local sections by Stoddart, Tawney, Wilson, 
etc., but it is doubtful if any better specimens have ever been 
unearthed than those from this bed, where it occurs in 
profusion. The excellence of preservation in many instances 
is remarkable, considering the friable nature of the rock.
