most of seven thick beds, capped by many thin beds, whose 
seams and coating are ochreous and yellow at the upper* 
part, where is a small filling up of a sort of magnesian 
marie, in which hundreds of perfect calcareous crystals lie 
loosely imbedded, from the size of the tenth of an inch to 
half an inch. This elevation of beds I take by computa- 
tion to be above 100 feet ; it is cut off by a slip coated 
thinly by spar, as most of our slips are - 
Next are, 
Three great beds of 12 feet each - 
Two more subdivided ------ 
One of 
Two of seven - - - - - - 
A mass being a perpendicular wall - 
Under which appears another slip facing the south 
with a surface : next are, 
Six beds— -coated by a thin regular bed - 
Another followed by three other smaller - 
Another slip of 20 feet ------ 
Two more beds 12 feet each - 
One bed 9 feet; one 7 feet; one 9 feet ; one 4 ; one 3 feet ; 
one 6 feet -------- 
One 4 feet ; one 3 feet ; one 6 feet ; one 5 feet - - - 
Six small beds, one and a half foot each - 
And here ends the Great Quarry at the second boundary
