Extract

DURING recent years considerable progress has been made in the study of the palaeontology of the Coal-measures. Attention has been directed to the flora, and to the marine and non-marine faunas. Although it is undesirable to attempt a complete revision of the classification of the Coal-measures until further work has been carried out, it may be useful to indicate certain conclusions which appear to be in accord with present knowledge.

page 498 note 4 Perhaps it is unnecessary to comment here on Mr. Bisat's use of the term Staffordian, proposed by Kidston to replace his term Transition Coal-measures. It is very undesirable that such a term should be extended, unless the floral evidence requires it, to include on the one hand those measures which Kidston called Radstockian and on the other the Middle Coal-measures.
