series shewn in the fifth cutting west of Bourton-on-the-Water 
Station (Op. cit. p. 123). It will be noticed that there is a very 
considerable difference between them, both in thickness and in 
general lithological details. 
There are two more cuttings before the tunnel is reached ; 
but as these cuttings only illustrate again the strata from the 
Gryphea-grit upwards, they afford no fresh details. 
It may be advantageous to give a generalized section of 
the strata which have been discussed in this paper. The letters 
for the beds are, to a certain extent, the same as those used in 
my paper on the Bourton line, so as to facilitate comparison.
