or layers of different colour and texture. The alternate bands 
or rings are coloured, one of a very delicate but pronounced 
pink, and the succeeding one of yellowish white ; each band 
one-third to one-half an inch in width. A preliminary micro- 
scopic section reveals undoubted organic structure reminding 
one of the stromatopora. A broken nodule is a very striking, 
not to say handsome object ; and so far as I can learn it has 
not been described or observed before from the Great Oolite 
rocks. A full description is reserved for another communication. 
A short way north of Foss Cross Station is the Stony 
Furlong Cutting, called by the contractor and his men, the 
“summit” cutting, from the fact that the highest point of the 
line is here, and is six hundred and thirty-seven feet above sea 
level. It isa little short of three-quarters of a mile in length, 
and is in places over forty feet in depth. 
I think it no exaggeration to describe this as the very finest 
section of the Great Oolite exposed in the whole Cotteswold 
area, and its investigation may profitably occupy the geologists 
of the Club for some time to come. It is absolutely unique in 
some of its features. 
The following account of it must not be taken as more 
than a rough preliminary survey, as at the time of writing 
it is not completely excavated, and access to the bulk of it is 
difficult, and to some parts of it still impossible. 
The beds dip southwards as a rule at an angle of about 
4—5°, and altogether a depth of strata of about sixty-five feet 
is exposed. There are three instructive faults in the cutting 
which are not quite clearly understood at present. 
At some future time it will be necessary to supplement this 
account, when a more carefully detailed examination has been 
made. So far as it goes, however, it will be found fairly 
accurate.
