Praises MT’s observations and asks her to repeat experiments on the the relation of sexes of butterflies to the nutrition of the larvae.

Is glad she will publish her observations on Drosera.

Asks her to probe worm-holes on grassy slopes with a knitting needle to ascertain whether they come out at right angles to the slope or to the horizon.
