    I n the human Kind, one of the largeft of thefe feminal Animalcula, when view'd through a Microfcope that magnifies 680 times in Diameter, appears to be about a lixth Part of an Inch ; and therefore its real Diameter, when reduced to a Sphere or Globule, cannot exceed Part of an Inch ; and therefore the lolid Content of one of thefe little People, is not more than TToooo^ooooo Part of a Cubick Inch. Now I fhail here fuppofe a Child when firft born to weigh fix Pounds, which is a middle Size for Children that come to Perfection. And fince the fpecifick Gravity of fuch a Body is very nearly the fame with that of Blood, the folid Content will be 160 Cu¬ bick Inches, quam proxima. And from hence it follows, that the Bulk or Magni¬ tude of an Infant at the Birth, is to the Magnitude of the feminal Animalculumu, or the fame Creature at the Moment of Conception, in the Proportion of 19200000000000 to 1. But the Logarithm of 19200000000000, is 13283801; which divided by 301030, the Logarithm of 2, gives 4412; and confequently 19200000000000, is fomewhat more than the 44th Power of a, the natural mean Interval, from the Conception to the Birth, is nine Lunar Months, containing 266 Days. Now 266, divided by 4412, quotes 6 ; That is.
