VI. <i>The effective resistance and inductance of a helical coil</i>

Abstract

Eff'ective Resistance and Indttctance of a Helical Coil.77 of the rods and cones on the retina (only the main essentials of which are referred to in this paper)~ seem to be still the subject of much discussion among physiologists to whom we must look for the exact interpretation of their bearing on problems in photometry.Dr. Edridge Green, for instance, in a recent lecture before the Optical Society*, expressed his dissent from the theory oF vision based on the supposed bebaviour of the rods and cones, and expressed the view that visual impulses are only received through the latter organs.But the general phenomena on which the theory mainly rests, and which have been utilized in this paper, seem to be well authenticated.
