Of Shells. 
Part I. 
The LITTLE ROUGH WILK. Nerites Turbine 
rugofo. 
The LITTLE KNOBED WILK. Nerites Turbine tube- 
rato. 
The GREAT ROUND-MOUTH'D SNAIL , with a 
Pearl colour. Cochlea ccelata. Here are three of thefe 3 of 
which two, are each above > 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 5 which eats away the rough 
and duller furface. 
The GREAT NAVLE-SHELL. Vmbilkus viarinus 
bidicws 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- 
ing like a Navle. 
A THIRD, with the fame fide befprinkled with a great 
company of fmall round knobs. 
The little Navle-Shell is well exprefs'dby Olearius,Tab.^ 
Fig. 7. Here are feveral of them kept in a Glafs. 
Not only this, but other turbinated fhells have their lid. 
Which, as Mr. Lyfter well obferves, is as it were another 
Valve. 
Spirit of Nitre droped upon this Shell, rifeth up with a 
ftrong eferrefcence. The admirable Virtue of this Shell is 
(a) Mufeum experienced, faith Wormius, (a) by men of very good 7iote, 
in ftainching of Blood 3 the flat fide hereof being only applied, 
with Spittle , to the Forehead. 'Tis ufual to lay a cold Key 
or Stone in the Neck. But if the fame, efpecially a good 
big Pebble with one fide flat, like a Painters Mullet, were 
apply 'd to the Forehead, I lhould expedt as good advantage 
from that, as from the application of this fhell. 
(b) Lib. de The Women in France, faith Boetius, (b) nimio Menfium 
Lapid. fiuore labora?ites, commonly take this fhell reduced to a 
fine powder, which they find to be a very good remedy, 
and keep it as a Secret. 
The LESSER ROUND-MOUTH'D SNAIL, with a 
ihorter knobed Turban.
