Review

The second edition of this well-known and much appreciated book has given the opportunity to the author to incorporate recent views in taxonomic algology, and to make the nomenclature up-to-date. To the interesting chapter “algal habitats” of the first edition a description of the vegetation of the east coast of Canada could be added. The chapter “collection and preservation” being a good and fairly complete narrative already in the first edition has been supplied with a useful note on staining slides made from herbarium material. In contradistinction to the first edition all specific names are written with a small letter.
