HISTORY OF THE OYSTER. 21

 oysters precisely in this state five or six times, as it is 

 scarcely possible out of a large number, even if ob- 

 tained from the same locality, to find two in similar 

 stages. I did not either observe the rounded bodies 

 with radiating lines in those last mentioned.
