levies, drawn from this general supply, and of all the machinery of communication, provisioning, and so forth. They will not be necessarily the “social superiors” of their commands, but they will naturally exercise the same authoritative command in warfare that a doctor does in a sick-room.] or for the naval and mercantile services, or into research and the literature of science. Some also would pass on to study for the profession of medicine through more special work in Chemistry and Physiology, and some with a proclivity for drawing and design would become architects, designers of appliances, and the like. The idea of the ordinary development of this course is not so very remote from what already exists in Great Britain as the Organized Science School, but, as with all these courses, it would be done in varying degrees of thoroughness and extension under varying conditions. This is the first of my three alternative College courses. The second course will probably seem less acceptable to many readers, but all who are qualified to speak will testify to its enormous educational value. It is what one may speak of as the Biological Course. Just as the conception of Energy will be the central idea of the Natural Philosophy course, so the conception of Organic Evolution will be the central idea of the Biological Course. A general review of the whole field of Biology--not only of the Natural History of the present but of the geological record--in relation to the known laws and the various main theories of the evolutionary process will be taken, and in addition some special department, either the Comparative Anatomy of the Vertebrata chiefly, or of the plants chiefly, or of several Invertebrated groups chiefly, will be exhaustively worked out in relation to these speculations. The first of these alternatives is not only probably the most invigorating mental exercise of the three but bears also more directly upon the practical concerns of life. Physiology will be taken up in relation to this special exhaustive study, and the “Elementary Physics of the Schooling” stage will be prolonged up into a treatment of Chemistry with especial reference to biological problems. Through such a course as this students might pass to the study of medicine just as well as through Natural Philosophy, and the medical profession would profit by the clash of the two types of student. The biological course, with its insistence upon heredity and physiological facts, would also give the very best and gravest preparation in the world for the practical concerns of motherhood. From it students would pass on illuminated to the study of psychology, philosophical science, and educational method. The training in the discussion of broad generalization, and much of the fact involved, would be a most excellent preliminary to special theological study and also to the advanced study of economics and political science. From this course also artists of
