In the Month of Augujl Oyflers are fup-*

opened an Oyfler on the fourth of Augujt , 
and took out of it a prodigious Number of 
minute Oyflers all alive, and fwimming 
brifkly in the Liquor, by the Means of cer¬ 
tain exceeding fmall Organs extending a little 
Way beyond their Shells, which he calls their 
Beards. In thefe little Oyflers he could dif-

one Egg is like another. 
As for the Size of thefe Embryo-Oyflers, 
he computes, that one hundred and twenty 
of them in a Row would extend an Inch ; 
and, confequently, that a globular Body, 
whofe Diameter is an Inch, would, if they 
were alfo round, be equal to one Million
