MATERIA MEDICA AND THERAPEUTICS.

ON THE THERAPEUTIC DIFFERENCES IN ELECTRIC CURRENTS, AND ON THE ELECTRO-DIAGNOSTIC EXPLORATION OF THE EXTENT OF THE FIELD OF VISION.

—C. Engelskjön has an extended article on this subject in the Nordiskt Medicinskt Arkiv, which is summed up as follows:

1. The experiences with patients suffering from cutaneous vascular neuroses, have demonstrated that in their local application upon the skin of the subject, with the use of the electric water bath, the two forms of electric currents exercise an inverse action upon the vessels, in that the faradic current dilates the vessels spasmodically contracted, while the galvanic current contracts the vessels that are actively dilated. In conformity with this difference of action, the faradic current produces simultaneously an increase, and the galvanic current a lowering of the temperature. There is no difference in the two poles of the galvanic current.
