COST PRODUCTIVE MEANS AND SPECIFIC PRODUCTIVE MEANS, Cost PRODUCTS AND SPECIFIC PRODUCTS
The remaining productive goods have certain specific qualities which distinguish them from cost-means. Consequently, those branches of production where their influence is decisive are distinguishable in their yield from the principal mass in which each branch is balanced against the others. The most conspicuous of this specific group are those which are remarkable for the pronounced scarcity of their occurrence. A spring of mineral water which has specific remedial virtue is an illustration. But even objects which occur more abundantly are to be regarded as specific productive means, provided they may be applied to only one use or a limited number of uses. Thus cinchona-bark is important only in the manufacture of quinine. It would retain its specific character, even though it were obtainable in large quantities.
