RECENT DISCOVERIES IN HEREDITY AND THEIR BEARING ON ANIMAL BREEDING.*
PROFESSOR W. E. CASTLE
EVERY breeder of animals is familiar with the great complexity of hereditary processes. He knows that characters of the most varied sorts are inherited. These relate not only to general size and proportions, but also to the structure of individual parts; and not merely to structural, but to functional peculiarities as well.
V. Prices and the International Movement of Metallic Money.
VII. Stability of Exchange.
VIII. The Value of Paper Money.
PROFESSOR J. LAURENCE LAUGHLIN
THE development of thinking about money is the most interesting portion of the history of political economy. The first dawn of economic principles came with the discussion of monetary phenomena, and monetary science has not only always had a peculiar practical interest of its own, leading to its constant appearance in political campaigns in all countries, but it has also had an organic life persisting in its full vigor to the present day.

I.Of Consciousnesses Simpler than Human Consciousness.
DR. HENRY RUTGERS MARSHALL
WHEN we are trying to think clearly we are wont to be disturbed if our friends accuse us of wandering from the sure grounds of science and entering the jungle of metaphysics. Nevertheless, it must be acknowledged that, without realizing it, all men do really devote a fair proportion of their thought to problems which, strictly speaking, are of a metaphysical nature : and the question as to the relation of ‘ mind to body,' which has an entrancing interest for so large a body of thoughtful people, is clearly one in reference to which no one can take a definite position without at the same time assuming an attitude in relation to fundamental metaphysical principles.
THE PREPARATION AND PROPERTIES OF COLLOIDAL MIXTURES.*
PROFESSOR ARTHUR A. NOYES
IT was by the well-known investigations of the English physicist, Graham, published in the seventh decade of the last century, that the general attention of scientists was first drawn to the existence of a class of homogeneous mixtures, differing materially in their properties from ordinary solutions, such as those of salt and sugar.
