Notes.

The article presents information on various publications. From John P. Kennedy, State Librarian of Virginia, there is a bulky Calendar of Transcripts, including the Annual Report of the Department at Archives and History. The preparation of a manual of theoretical biology for the general scientific public is really a far more difficult enterprise than in days of Herbert Spencer's "Principles of Biology," when protoplasm could be regarded as simple homogeneous fluid. The latest issue of the Harvard University Bibliographical Contributions deserves wide advertisement and circulation.
