Experimental observations of the bootstrap and Pfirsch-Schl̈ter currents, predicted by neoclassical transport theory, are presented. Detailed measurements of the parallel plasma currents in a toroidal octupole agree, within the separatrix, with theoretical predictions. Observations of the spatial structure, collisionality, and toroidal field dependence of the complete current and the ion portion of the current are discussed.
