flattened, and with the capitals of the attached shafts 
octagonal instead of round. Shafts, as in Somersetshire, 
are very often carried up from the pier to support the 
roof. Exceptional forms of pier also oceur, as I shall have 
occasion to point out when I come to desceribe particular 
examples. 
But the great difference in the internal elevations is to 
be found in the clerestory. In Somersetshire a single 
window, sometimes, as at Wells, Bruton, and Martock, of 
great size, but more commoniy of moderate dimensions, 
is placed over each arch. In almost all the grand East- 
Anglıan examples, two clerestory windows, as I have 
already mentioned, are placed over each arch, produeing 
those illimitable ranges of windows, which have so striking 
an external effect, and which reduce the clerestory wall to 
a nonentity, leaving hardly anything but a system of glass 
and mullions. 
Now as this arrangement of the clerestory tends so con- 
spieuously to diminish the amount of unocceupied space in 
the upper part of the wall, this has perhaps led to its 
being far more common than in Somerset, though still 
very far from the general rule, to fill the spandrils above the 
main arches with panelled ornaments of various kinds. 
When, as frequently happened, roof-shafts were carried 
up from the piers, while a shaft was also made to spring 
from the top of the arch, the spandril became so promi- 
nently marked as a piece of blank wall, that the idea of 
filling up the space in some way or other must have been 
imperatively suggested. I remarked in a former paper 
that in such a case it was far better to treat this space as 
a spandril, like that over a doorway, than to continue the 
elerestory window downwards, in the form of panelling. 
In the former case, while the whole design is artistically
