PHILOSOPHY OF ETHICS. Critical and constructive review of ethical theories. Psychological questions as to the nature and origin of moral faculty ruled out as irrelevant. Two hours. HISTORY OF PHILOSOPHY. From Descartes to the present time. Five hours. The Philosophical Club, organised in 1886, has since that time maintained stated meetings for the furtherance of its members in philosophical studies. Last year, under the auspices of the University, a special course of five lectures on Educational Psychology was given before large audiences by William T. Harris, LL. D. The topics treated were as follows: 1. Introspection contrasted with external Sense Perception. 2. Mental Pictures _versus_ General Ideas. 3. The Logical Constitution of Sense Perception. 4. Physiological Psychology. 5. The Psychology of Mathematics, Æsthetics, and Ethics. The courses are for single terms only. B. P. BOWNE. JOHNS HOPKINS UNIVERSITY.

SOME NEWLY-DISCOVERED LETTERS OF HOBBES. By the _Editor_. _Our Space-Consciousness._ In this article Mr. Herbert Spencer replies to criticisms, by adherents of Kantian doctrine, of objections contained in §§ 326-335 of _The Principles of Psychology_. He objects that the disciples of Kant "cannot imagine how it is possible that our space-consciousness can have arisen out of that which was not originally a space-consciousness."
