Note 15 — ANGERMANLAND.

This cavern has been visited by other naturalists since the time of Linnæus, among whom was Dr. Olaf Swartz, the present Bergian Professor of Botany at Stockholm, well known by his various excellent publications, who gathered here the same Byssus (cryptarum) which Linnæus found in the other cavern at Brunæsberget. Both their original specimens are now in my possession.
