Magnetism is stated to act as a line, electricity as a surface, and chemistry as a solid; for all which Mr. Coleridge refers to certain physical experiments. The predominance of magnetism is characterised by reproduction, that of electricity by irritability; and irritability, which first appears as muscle, gradually rises into sensibility as nerve. The limits of a mere introduction will not permit me to examine Mr. Coleridge's first principles more in detail; and I can but briefly notice their application to the successive stages of ascent, from the first rudiments of individualised Life, in the lowest classes of the mineral, vegetable, and animal creation, to its crown and consummation in the human body. Beginning with magnetism, by which, in its widest sense, he means what he improperly calls the first and simplest differential act of Nature (he should rather have said the first and simplest conception that we can form of a differential
