I t 2 An 'Examination of the 



laft Stage ; that the fuppofed Embryo 

 Sole is no more than a Matrix, and 

 that there is a continual Succeffion 

 of them fupplied from the Provi- 

 iion of Spawn, each Globule of which 

 may hatch gradually, as the Ani- 

 malcules drop off. In Effect, the 

 Spawn is known by an ingenious Per- 

 fon of my Acquaintance, who, has 

 frequently obferved it, to diminifh 

 infenfibly, and the Cavity to be filled 

 up to a convex Surface by fome o- 

 ther adventitious Matter, which in 

 the Opinion that what I call the 

 Matrix is an Embryo- Sole , he fup- 

 pofed had been exhaufted in the 

 Nourishment and Increafe of it, till 

 the Difcovery of the Animalcules, 

 which put him to a ftand, as well 

 as myfelf. After all, both Opi- 

 nions may have fomething of Truth 

 in them, and the Embryo Sole, if 

 it be fo, perform the fame good 

 Offices to the Progeny of the Shrimp, 

 as the Mother Shrimp does to it. 

 But however that Matter be, the 

 Subject in my Opinion, is well worth 

 Observation., and deferves to be clear- 

 ed up.
