July 3^d 1869. Variability under nature   Important^t1
I think it agrees best with what we see under Dom. that characters become & long remain fluctuating, & only occasionally actually new characters «parts» appear^t2.— By Pangenesis we can understand that changed conditions have affected affinities of tissues & gemmules.—
That conditions are concerned in causing var.^y we may infer from domestications & monstrosities & sports or modifications; & from the same species varying more in one locality than another — New effect of chemical composition Lawes & Gilbert — it is absurd to say that plants growing ever^t3 closer together can expand to same conditions & their parents before them.— Again plants in New Zealand being so variable — &^t4 this agrees with fluctuations of characters long remaining    Again all spe. of Rubus, are descended from 1 progenitor & yet some few sp. are not highly variable — How about Hieracium, Cirsium &c. ask Nägeli? Again I think most protean genera are large — Is not Epigæa of Meehan an exception? & this w^d indicate that variability is caused & is inherited, & there is evidence from Hybrids that variability strongly is transmitted, & this is just as possible as Trimorphism or Dimorphism being transmitted — (over
