a, a, a. Layers of flint nodules, alternating with chalk strata.

' sponges, but of so perishable a nature as to leave but few 
traces of their organization, save their general form. Speci- 
_ mens may however yet be found with the structure pre- 
_ served, for many years elapsed after the first discovery of 
_ flint ventriculites, before I obtained examples that threw 
‘ light on their origin and formation.
