FIG. 8-SPLIT SHELL DISCLOSING EMBEDDED PEARLS. 



Pearls embedded in the shell are generally found 

 in close proximity to the hinge, and in splitting 

 shells open to examine a " blister," an embedded 

 Pearl has often been found (see Fig. 8.), at a place 

 where the surface of the shell gave no indication of 

 its presence.
