[6 verso (blank)]
You can select cattle & sheep for horns & yet no difference in calves — how is this in young pigeons — dogs — cattle? As we see the frame of animals can adapt itself to course of life, as in trades there is no reason, why the peculiarities shd be born, — may come in corresponding time of life of offspring — No peculiarity in external
structure can be concepcional, as limbs &c &c only appear late in pregnancy, & then may just as well be born a tendency to alter or assume some form late in youth, — only facts can decide —
some peculiarities may be early impressed & others later — All poultry with same down-feathers.
