The FLAT BOLTHEAD. Anchorites. Of affinity with that well described by Wormius (b) (b) Mus. lib. 1. Sect. 2. c. 13. with the Title of Silex venabuli ferreum Cuspidem exactè referens. By Moscardo, (c) with that of Pietre Ceraunie; who also figures it with three or four Varieties. This like those, is a perfect Flint, and (c) Mus. lib. 2. c. 50. semiperspicuous. 'Tis likewise in the same manner, pointed like a Speer. Having at the other end, like those of Moscardo, a short Handle. But moreover, hath this peculiar, that 'tis pointed or spiked also backward on both sides the Handle; with some resemblance to an Anchor, or the Head of a Bearded-Dart: from whence I have nam'd it. 'Tis likewise toothed on the edges, and the sides as it were wrought with a kind of undulated sculpture, as those before mention'd.
