This would, however, require an incred- ibly rapid cell growth, and we are compelled to assume that although the growth and disappearance of the secreting cells is of the greatest im- portance in furnishing the organic constituents of the milk, these sub- stances are not derived solely from the breaking down of the cells, but 40.
