Left, faid he, the Fifh fee you, for then he will fhed his 
Pearl in the fand : Of which I believed no more, than 
that fome Mufcles had voided their Pearls, and fuch are 
often found in the Sands. 
I conceive that thefe Pearls if once dark will never be 
clear upon any alteration in the Health or Age of the 
Mufcle, or of the Moon and that if the firft Seed be

dark at the other it may be enquired whether the 
Colour ever changed from one to the other, or was 
primigenial, as they ftill continue. I fhall defire your, 
kindneft in (ending me fome Heads of Enquiries, for £

Apothecary as other more, clear, and what better En- 
gines you can direct us unto to take them up, with, no 
place being deeper than i z Feet. 
I fend you alfo herewith fome Stones of aiK Amber 
Colour taken out of a Spring called Cranhoum-.SpriuQ
