Macmillan and Co. have made arrangements for the issue in New York and London of a "Dictionary of Philosophy and Psychology" under the editorial supervision of Professor Baldwin of Princeton University. The work is to have the following general features:

1. It will contain concise definitions of all the terms in use in the whole range of philosophical study (philosophy, metaphysics, psychology, ethics, logic, and c).

2. It will contain such historical matter under each term as may be necessary to justify the definition given and to show that the usage suggested is the outcome of the progress of philosophy together with special historical articles.

3. It will have very full bibliographies both of philosophy generally and of the special topics which are connected with it.

The following assignments of topics with the names of the authorities who will contribute original matter are already announced:
