第 14 頁 - Nor could he long cling to the theory that God had deliberately deceived his children, however pious the reason for deception might be. So in 1853 Peirce advanced another theory, namely that science and the Bible have equal authority, but in different spheres: We acknowledge . . . that science has no authority to interfere with the Scriptures and perplex the Holy Writ with forced and impossible constructions of language.

India-rubber was for many years only known as a means of erasing pencil-marks, and that gutta-percha was, until very recently, only used for axe-handles, we shall be inclined to study new applications of old materials in a very hopeful spirit. THE following papers were presented, and most of them were read, but no copy of them has been furnished for publication : — I. MATHEMATICS AND PHYSICS. 1.
