17th. Even though I went about busily, there was nothing in particular to see apart from a sort of spittle on the grass everywhere. The common people call it frog-spit and, when you wipe it off, a small insect is left behind; flesh-coloured, like a small grasshopper though still immature – a sure sign that that is what it will become even though it has not yet learnt to do leg-kicks.4 I wiped off this liquid and let the creature sit there. An hour after I had arrived there was once again a sort of frothy bubble, which demonstrates that the insect blows out this froth itself, thus protecting itself against the strong heat of the sun which would otherwise quickly cause its delicate skin to dry out.
