3.1.
It is impossible to give rules that will cover every conceivable problem in capitalization; but by considering the purpose to be served and the underlying principles, it is possible to attain a considerable degree of uniformity. The list of approved forms given in Chapter 4 will serve as a guide. Obviously such a list cannot be complete. The correct usage with respect to any term not included can be determined by analogy or by application of the rules.
