affords but an imperfect Refemblance 

 of a Sole. In effed:, Mr. Dejlandes* 

 as it appears by the Memoirs of the 

 Royal Academy of Sciences, 1722, 

 took a confiderable Quantity of thefe 

 Shrimps, and preferved them alive 

 in a Veffel of Sea- Water, where 

 after the Space of twelve or thirteen 

 Days he found eight or ten little Soles. 

 He repeated the Experiment fe- 

 veral Times, always with the lame 

 Succefs. After this he kept alive 

 in Sea-Water Soles alone without 

 any Shrimps for a confiderable Time, 

 and tho' they Spawned in the Veffel, 

 yet the Spawn came to nothing; from 

 whence he concludes, that thefe Ob- 

 jects found upon Shrimps are really 

 the Embryoes of Soles, as they ap- 

 peared to him to be in the Microfcope, 

 and that the Spawn of the Sole re- 

 quires the Affiftance of the Shrimp 

 to hatch it. Mr. Dejlandes might 

 have placed this Confequence in a 

 much better Light, and excluded 

 effectually all Objedtions, had he ta- 

 ken the Precaution to have counted 

 the Number of the fuppofed Em- 

 bryoes upon a fmaller Quantity of 

 Shrimps, and compared the Increafe
