Professor Pollock's Last Lecture.

Sir Frederick Pollock will deliver the fifth and last of his series of lectures on the "Expansion of the Common Law," in the New Lecture Hall at 12 o'clock today, his subject being "The Law of Reason--Natural Justice in the Common Law."

Professor Pollock spoke yesterday on "The Law of Reason--The Law of Nature and of Nations." After defining the law of reason he showed how it had been derived from the ethical speculations of great philosophers. He outlined the growth of equity and spoke of the limitations of its field of usefulness. In the latter part of his lecture he explained the law of nations and refuted the assertion that the law of nature was the supreme authority.
