But just as the chemist is able to build up complex organic compounds from simple substances, so Spencer supposed that organic compounds were evolved in nature. He supposed the evolution of some substance like protein, which is capable of existing in many isomeric forms, and of forming with itself and other elements, substances yet more intricate in composition.

To the mutual influences of its metamorphic forms under favouring conditions, we may ascribe the production of the still more composite, still more sensitive, still more variously-changeable portions of organic matter, which, in masses more minute and simpler than existing Protozoa, displayed actions verging little by little into those called vital.

of the concept of matter, or of the apparent simplicity of life in its humblest expressions, will seek to foreclose the question of the possible origin of living matter from not-living matter. The conclusion which most biologists accept is, that while there is no known evidence of not-living matter giving origin to living organisms, this does not exclude (_a_) the possibility that this once took place, or (_b_) the possibility that it may be made to take place again. It must always be remembered, however, that there is a great gap between a drop of living matter and an integrated living organism. We may firmly say that if living matter was once evolved from not-living matter, it must have been the outcome of long preparatory processes, that if it occurred, we cannot at present suggest
