Another volume has been added to this series, and another

valuable guide to the geological succession of plants ; and the policy of allowing illustrations to explain themselves where possible has certainly produced an interesting botanical history. The early Palaeozoic, the Devonian, and the Carboniferous forests and eras are profusely illustrated, and will afford much pleasure to students who will also not despise the remarks Sir J. W. Dawson offers to them on the general laws of origin and migration. The author has managed to economise space and avoid cramming in his history of plants. It is written in a terse, clear, and forcible manner.
