From A. R. Wallace 4 February 1866
Summary
Looks forward to reading Variation.
Explains how two or more female forms occur in one species through selection. The physiological problem remains of how each produces offspring like the other without intermediates. Is not CD’s case of varieties that will not blend the physiological test of a species needed for "complete proof of the origin of species"?
"Travels" postponed.
