162 Mr. Davy’s Account of some analytical Experiments , &c. 
I have examined a fossil from near St. Austle, in Cornwall, 
very similar to the fossil from Barnstaple in all its general 
chemical characters ; and I have been informed, that an analysis 
of it, made by the Rev. William Gregor some months since, 
proves that it consists of similar ingredients. 
Dr. Babington has proposed to call the fossil from Devon- 
shire JVavellite, from Dr.WAVEL,the gentleman who discovered 
it but if a name founded upon its chemical composition be pre- 
ferred, it may be denominated Hy dr argillite , from tty water, 
and u^yCKKoc clay.
