Of Shells. 
Part I. 
The LITTLE ROUGH WILK. Nerites Turbine 
rugofo. 
The LITTLE KNOBED WILK. Nerites Turbine tuber 
rato. 
The GREAT ROUND-MOUTH'D SNAIL ; with a 
Pearl colour. Cochlea cxlata. Here are three of thefe 5 of 
which two, are each above i a foot wide. Their pearly 
glofs,on the outfide is artificial 3 within,natural.The natural 
colour without is fometimes green, with white and bay 
fpots. 
One way whereby it receives a bright pearl colour, is 
by being fteeped in Vinegar 3 which eats away the rough 
and duller furface. 
The GREAT NAVLE-SHELL. Vmbilicus marinus 
Indie us major. It is the lid of the Cochlea C aetata 3 and hath 
its Name from its lhape. Very well defcribed by Wormius. 
The LITTLE NAVLE-SHELL, with wrinkled edges. 
A SECOND, with the Convex fide more plainly wind-

A THIRD, with the fame fide befprinkled with a great 
company of fmall round knobs. 
The little Navle-Shell is well exprefs'd by Olearius,Tab.^.

or Stone in the Neck. But if the fame, efpecially a good 
big Pebble with one fide flat, like a Painters Mullet, were

from that, as from the application of this {hell. 
(b) Lib. de The Women in France, faith Boetius, (b) nimio Menfium 
Lapld. & fiuore labor antes, commonly take this fhell reduced to a 
fine powder, which they find to be a very good remedy, 
and keep it as a Secret.
