The in-plane resistivity {rho}{sub {ital ab}} of 60-K YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital y}} is equal to (340{plus minus}30) {mu}{Omega} cm at 290 K and varies approximately linearly with temperature {ital T}. The anisotropy {rho}{sub {ital c}}/{rho}{sub ab} increases from {similar to}100 to 2000 as {ital T} decreases from 290 to 80 K. In the four crystals studied {rho}{sub {ital c}} is observed to increase monotonically with decreasing {ital T}. This is an intrinsic property of the normal state which has not been explained by conventional transport theory.
