Shore fuficiently. This is evidently confirmed by com-' 
paring the Specimens from this Coafiy recited in the 
Works of our mofi celebrated * 'Naturaliftsy with thofe 
in the enfuing Catalogue. The Author doubts not that 
many curious Specimens have efcaped his InquirieSy and 
as the Cliffs ^are daily dropping their Contents more or 
lefsy he is fully affured that there will always remain 
a Variety fuffcient to gratify every Lover of the Studyy 
whenever they may choofe to take a Trip thither. But 
alas I One difagreeable Circumftance attending a con- 
Jiderable Part of the Foffils here coileSledy is, that they 
are fo much impregnated with Pyritical Matter, that 
after being for fame Time placed in a Cabinet, the 
Salts thereof fhoot and entirely deftroy them. Happy 
would it be, could feme certain Remedy be difeovered 
whereby this Accident might be prevented. The Lofs 
of many valuable Specimens by this Caufe, together 
with his Difiance from any inquifiiive and able 
NaturalifiSy at laft induced the Author to difpofe of 
his whole Coll&Bion to Ingham Foster, Efpy

Mr. Dale, and Dr. Hill.
