Note cc — BOOK VIII.

The Aleppo-Galls, wherewith we make Ink, may be reckoned of this Number, being hard, and no other than Cases of Insects which are bred in them; who when come to Maturity, gnaw their Way out of them; which is the Cause of those little Holes observable in them. Of the Insects bred in them, see Philos. Transact. Nᵒ. 245. Of this Number also are those little smooth Cases, as big as large Pepper-Corns, growing close to the Ribs under Oaken-Leaves, globous, but flattish; at first touched with a blushing red, afterwards growing brown; hollow within, and an hard thin Shell without. In this lieth commonly a rough, white Maggot, which becomes a little long winged, black Ichneumon-Fly, that eats a little Hole in the Side of the Gall, and so gets out.
