Pot III.— Oct 20th 1880

Tiles in Gizzard

10.30' a.m — Pot full of mud from pond & ferruginous sand no or extremely few stones passed down, very damp — 6 worms put in — on surface much broken red tiles, hard, from verandah—

Some of the same but kept in tin box — for comparison.

11.10 a.m Every worm has disappeared & burrowed itself except just tip of tail of 2 of them. Gave them leaves of green & red cabbage, turnip — carrot, celery beet & cherry, all rather oldish leaves

Oct 21st 8 a.m tips of carrot leaf drawn in much blackened or browned — cherry a little gnawed — This blackening must have occurred in abt 12h

22 carrot & cherry still favourite, but very little acted on.

25th Taste of all leaves carrots most preferred & next cherry (Nov. 8th all leaves removed)

Nov 10th many bits of tile in castings — These present exactly same appearance as washed fragments — not at all rounded — nor discoloured. Do they swallow them mainly to carry them down, or may they do some attrition without being rounded.

Nov. 18th many bits of tiles, quite red, in castings & bits of stone — on bit of tile was above 3 mm long & above 2 mm in length; not in the least discoloured. — One worm had evidently picked up much red dust from pounded tiles, so that castings was reddish & it

& it contained an unusual number of bits of tiles. None of them showed any trituration. These worms were feeding on earth for they had no leaves & these make the facts of 100 very little stones in castings that more interesting.

Nov 22d broke earth in pots to pieces — astonishing number of large bits of tiles in holes — some on sides & some embedded quite many dragged down by mainly adhering to worm bodies — quite red. (N.B. kept bits of verandah tiles for several days in acetic acid as red as ever & not corroded also some five leaves dragged far down; but not lining holes neatly.

Nov. 23d — 3 worms examined — 3 minute with gizzards almost empty atoms of tiles in the gizzards of 2 other empty. — 2 other worms had many grains of sand & some small stones in them, but very little vegetable matter or even in one 3 stones of tiles & a concretion, which certainly seem worn. These tiles all tiles red — particles do not appear more worn than the standard bits of tiles which had been washed & then dried. Gizzard particles preserved.

25. examined 2 more worms — much sand & some little stones (& 1 concretion in both — in one 2 atoms of tiles. red.

Trituration.
