In the middle of June a large specimen of Aphro- 

 dite cirrosa produced an immense number of eggs, 

 probably not fewer than 10,000, or perhaps more. 

 This great profusion, accumulated on the bottom of a 

 glass vessel, was of a reddish hue, each individual 

 ovum being minute, white, and globular to the naked 

 eye; but as they all proved abortive, we are unac- 

 quainted with the form of the embryo, or the history 

 of the progeny to which they give birth.
