effect whatever onproteids, he has made a study of the formation of albumin in plant cells, and finds there is a labile or active albumin in living matter chemically unlike the ordinary albumin stored in seeds and eggs. This exists as a reserve material in plants and undergoes chemical change by the same influences causing death to protoplasm. By many experiments it is shown that the chemical activity of cells is akin to the phenomena of catalysis. The conclusion is reached that there is an oscillation of atoms, or peculiar mode of motion, existing in labile proteids which is the source of vital activity; this being in its turn "but one of the vicissitudes of solar energy."
