Strongest objection to my theory - is that there must have been enormous development of Pterodactyle forms - probably nearly as much as Birds before Lias of Plants before Coal - And this whole time from lowest Silurian to now a mere latter fragment of time since life entered on this planet - well may mind stages & recoils - Think of which analogy of recent progress in Geology leads to.

Objection of not finding series in any one formation weak - for without formation being accumulated with scarcely any change of condition - there would be migration of the coexistent forms (3 sets in Lias. Strickland)

Moreover rare species are changed

The first appearance of Mammal & Bird & under form - Bats Pterodactyle, Libellula &c & perfect is most serious difficulty to my theory

Shells perfect in lowest Silurian not objection

Europe graduating from Pelagic condition - several remarks over paper (aaa) my only answer - Earliest forms of Reptiles not perfect

Also of Fish??? Reptile-like Fish =

Thinking about first appearance of perfect Bats in Eocene - it looks like perfect forms coming from other planet but by my theory Bat before it became perfectly winged probably would be confined animal, like man before reason made him cosmopolite & hence little chance of finding any but perfect Bat in fossil State – (was world in Secondary period so many separate worldlets like Australia??

develops few forms there found.
