Spheroidal concretions from the Yarra estuary which were to found to contain plant-remains were described by Mr. Chapman recently in this journal. The structures in themselves are of considerable interest to geologists, and also to palæobotanists from the fact that they contain “matted fragments of woody and foliaceous-material.” They were made the subject of some comparisons with the calcareous concretions from the Lancashire Coal-measures, and as a result certain general considerations were brought forward, which call for comment, and which are of sufficient importance to receive attention.
