SOME ACCOUNT OF THE 



We may judge with greater or lelTer probability by 

 the appearance of the pearl-fhell, whether they contain 

 pearls or not. Thofe that have a thick calcareous 

 cruft upon them, to which Jerpuhe (Tea tubes) Tubull 

 marini irregular iter intorti, Crijla-gali Chamar lazuras, 

 Lepas tintinabulum, Madreporee, MUlippre, Cellipore, 

 Gorgont<e, SpongLe, and other Zoophytes are f aliened, 

 have arrived at their full growth, and commonly con- 

 tain the bell pearls ; but thofe that appear fmooth, con- 

 tain either none, or fmall ones only. 



Were a naturalift to make an excursion for a few 

 months to Manar, the fmall ifland near Jafna and the 

 adjacent coail, he would dil cover many natural curio- 

 fities, Hill buried in obfeurity, or that have never been 

 accurately described. 



Indeed no place in the Raft Indies abounds more 

 with rare (hells, than theie : for there they remain 

 undiiluibed, by being fheltered from turbulent 

 feas, and the fury of the furf. I will juft name a 

 few of them ; viz. Tellina foliaca Lynn *, Tell, Speng- 

 lerit,Arca culculata -j-, Area No<e,Jolen anatinus Linn.
