45. The fmall round Mufcle (b) is lefs frequent than the reft. I 

 found fome of them in a piece of water at Brome-Haugh, near 

 Chipchace, with the deprejjed orbiculated Cochlea. It is of a globofe 

 figure, of the fize of a fmall hazel-nut, and of a dark olive 

 hue. 



The exterior coat of the Mytuli, and other fhells, may be eafily 

 taken off by boiling in any ftrong Lixivium, or lye, and their in-

 rious flower, or grotto-works, or for medical ufes. The interior 

 pearly fubftance of the MytuH, reduced to powder, is of equal 

 efteem in medicine with crabs eyes or pearls.
