and has impressed me, combined with considerations as to other areas, 
with the possibility that we have here a transitional bed connecting 
the Upper Lias and Inferior Oolite, equivalent to the simiiar bed 
(termed by Dr. Lycett “the cynocephala stage”) of Frocester Hill 
and the Cotswold district. 
I would here acknowledge the consideration and courtesy of Mr. 
Bass in preserving and presenting me with many fossils found in 
his pit. 
Another good section of these beds is temporarily open on the pre- 
mises of the County Lunatic Asylum, situated at m, at the eastern 
outskirt of Northampton, and about a mile and a quarter S.E. of 
Mr. Bass’s pit. This will serve further to illustrate the variable 
character of these beds.

One set of joints in this section have a direction N.W. and S8.E. ; 
and the crevices are frequently filled with a soft white material, 
which, upon analysis by the recently deceased Dr. Berrill (formerly 
a student at the School of Mines), was shown to be allied to 
allophane. 
The general coincidence of the lower part of this section with 
the same portion of the last, classed under E, is observable. 
The fossils obtained by Dr. Berrill from this excavation have 
been courteously presented to me by the representatives of the 
lamented gentleman, who was cut off in early prime, and in the midst 
of an active career, by an attack of fever, in December last. A list 
of these fossils is given in the tables; but I may notice here the re- 
markable way in which delicate casts of the tests of Zrigonie, Tan- 
eredia axiniformis, and some other small shells have been preserved 
(showing in the same specimens, perfectly, the exterior sculpture and 
the internal hinge), also impressions of a fragment of Cidaris Fowleri 
and of a spine of Cidaris Wrightii, the abundance of Pinna cuneata, 
and the state of preservation of many of the tests of the shells 
found.
