A IV S ; and hereby the Defedls in the Stone ftem to 
be fupplied with a right Nunriber of Letters in each Vacu- 
ity, and this I the rather apprehend to be right, becaule 
'tis now a Year fince I communicated the fame to an in- 
genious Gentleman, Dr. Cay of tfew-Caflle (who was the 
Perfon that courteoufly fent me the Copies of both) and 
I hear not itis difapproved by any Critick upon the Place. 
VIL Of the Manner of thp Generation, of Eels. 
By Mr. Benjamin. Allen. 
THE Manner of the Generation of Eefsj as familiar 
a Subjefl: as it is, has been a Queftion unrefolv'd 
ever fince Ariftotle^ and reputed Spontaneous : And the 
Reafon of the Difficulty of difcovering it , is the different 
way oPGeneration, and that they brz^& \n February ^ 
a time when few are taken but what are preferved m 
Trunks or Ponds, where they bi-eed nor. This I exa* 
min'd Two Years fince, in fome taken at a Mill , in 
which Holes they breed, efpecially near Gravelly Shal- 
lows, and found one with Egg, another with Six young 
ones in the great Intjeftine, which I call the Strait Bow- 
el- that delcends immediately from the Pylorus until 
the Winding begins ; they were faftned to a very fmall 
Placenta each, which was fixt to the Inteftine, the Mefe* 
raicks at that time were very turgid : The Eggs were 
on the Outfideof the Inteftine. It is certainly Vivipa- 
rous, and feeds notj ac le^aft Grofs, in the Winter, du- 
ring all which they lye ftill till they have difcharg'd 
f heir Young.
