Blackcaps eat the berries of the honey-suckles. Mrs J. White, after long & severe campaign carried on against the Blattae molendinariae, which have of late invaded my house, & of which she has destroyed many thousands, finds that at intervals a fresh detachment of old ones arrives; & particularly during the hot season: for the windows being left open in the evenings, the males come flying in at the casements from the neighbouring houses, which swarm with them. How the females, that seem to have no perfect wings that they can use, can contrive to get form house to house, does not so readily appear. These, like many insects, when they find their present abodes over-stocked, have powers of migrating to fresh quarters. Since the Blattae have been so much kept under, the Crickets have greatly encreased in number.
