From Francis Darwin   [1873]

New University Club, | St. James’s Street. S.W.

Dear Father

Klein says the water ought to be changed every day1   I should think you might draw if off with a syphon, which Jim could rig up with glass tubing & indiarubber ditto— I found I could pour off a good deal of water by stretching a bit of gauze over the lip of the basin.

I left a bit I used on the fern heap in Deadman’s corner; but I should think the syphon wd be best— Please tell G the Revalenta shop is shut today.2 Klein says his discovery about toads’ ova does not bear on pangenesis.3 I don’t know why he said it was good for you.

Yr affec | Frank Darwin
