Summary: (1) It is impossible to say how much one variable depends on another. (2) The meaning
of "dx'_{i}/dx_{k}" is given. (3) The Question "Does x_{i} depend on x_{k}" is meaningless. (4) New form of matrix test for dominance is given. (5) Definitions
given of (a) x_{i}t curve depends on x^{0}_{k}, (b) x_{i}t curve is independant of x^{0}_{k}, (c) x_{i} dominates x_{k}, (d) "parameter".
Summary: I have decided in future to end the Sections with a Summary. It may perhaps force rather more tidiness into the ideas and will be useful for reference.
