three curious People counted, with all the 
Care they were able, as many of the Eggs 
or Row of a female Cod-fifh as weighed a 
Dram, and agreed pretty well in the Num¬ 
ber, which they wrote down. They then 
weighed the whole Mafs ; and fetting down 
eight Times the Sum of one Dram for every 
Ounce, which contains eight Drams, all 
the Sums together produced a Total of nine 
millions three hundred and thirty-four thou- 
fand Eggs *. 
Now fuppofing (as Mr. Leeuwenhoek 
does of the Semen Mafcuiinum of Frogs) that 
there are ten thoufand Animalcules in the 
Milt for each one of the Female Ova in the 
Row, it will follow, that fince the Female 
Row is found to have nine Millions three 
hundred thirty-four thoufand Eggs, the 
whole Milt of the Male may be reckoned to 
contain ninety-three thoufand four hundred 
and forty millions of Animacules: which, 
though greatly fliort of the drib Calculation, 
is almofl feven Times as many as the whole 
human Species. 
To find the comparative Size of thefe 
Animalcules , Mr. Leeuwenhoek placed a 
* Four Millions and ninety-fix thoufand Eggs were com¬ 
puted in the Roe of a Crab ., each of which received itsNou- 
rifhment by a Rope from the Crab's Body, Vide Arc . Nat .
