Gizzard of Worms
Oct 20th 1880 — I found to day embedded in castings in sand
Pot I 2 of the Black glass — beads (with inside packed with sand) & a fragment of blue glass — This proves that worms both hard objects — incredible, considering proved powers of taste, that they mistook them for food. These beads show no signs of abrasion.
(N.B. In Ch IV I have discussed pretty fully about the sucking of stones) I have only just alluded to stones in gizzard in Ch I.
