Not illustrated. 1896 Excerpt: ...heterodromous in order to secure this excitation, a fact previously referred to in connection with the galvanometer experiments, and interesting since the partial immunity of this organ to electrical currents, unlike that of Twpedo is evidently more pronounced for currents of a direction similar to those of its own activity. The records of the response resemble, in their general features, those previously described, but differ, inasmuch as they are fused with the residuum of the induced current. The response to homodromous stimulation will be referred to in detail later, as it presents certain special features. The Response to the Heterodromous Induction Current. The organ was excited by the break of a current produced by 5 volts in the primary coil, the core of which was removed and the secondary coil placed fully over it. The record of the response to heterodromous stimulation in Plate 2, fig. 8, shows first a few oscillations at the break of K3 and then the rhythmical peripheral response. The initial response effect shown in the negative is interfered with by the residuum of the exciting shock. It commences 007 second after the induction current, and is followed by 13 successive similar effects, and probably many others which were not recorded on the plate. The time interval from the commencement of one change to that of its neighbour averaged 008 second, hence the successive changes occurred at rate of 120 per second. The temperature of the organ was 15 U. Section 5.--The Influence of Temperature on the Time Relations of the Heterodromous Resj)onse. The organ strip was placed upon a glass vessel as a stage capable of being warmed and cooled by running water, and the response to direct excitation by the heterodromous induced current was then recorded whe...
