Variety m1 is supposed to have produced two varieties, namely m 2 and s2, differing from each other, and more considerably from their common parent (A). We may continue the process by similar steps for any length of time; some of the varieties, after each thousand generations, producing only a single variety, but in a more and more modified condition, some producing two or three varieties, and some failing to produce any. Thus the varieties or modified descendants, proceeding from the common parent (A), will generally go on increasing in number and diverging in character.

Messer Gasparinod'Oria (as I have heretofore told you) questing as a common Pyrat onthe Seas, tooke us and sent us home to his house as slaves, where(as yet) he detaineth him. I would likewise have you send into Sicily,who informing himselfe more amply in the state of the Countrey, mayunderstand what is become of Henriet my Father, and whether he beliving or no.
