Since that time I have frequently communicated with these 
gentlemen, also with the Rev. Peter Hawker of Wood- 
chester rectory, Minchinhampton, and Dr. Carpenter of 
Lyme ; and have received from them many specimens I had 
not seen before, some of which it was difficult to determine

of a third communication to this Society. 
There is also another reason for bringing forward these 
facts, and for doing so without any unnecessary delay ; for, 
as my former papers were the means by which I acquired 
them, their being made known to the public, may lead those
