Publisher's Synopsis
Excerpt from Abstracts of Theses Presented by Candidates for the Master's Degree at the August Convocation, 1930
The present study is a fundamentally different approach to the whole problem. The aim Of the present writer is to determine the magnitude and character and range of the photo-electric effect of excised eyes of animals occupying different positions in the genetic series. The apparatus involved consists chiefly of a delicate spectrometer, and a quadrant electrometer. Of course there are many other items of an accessory character. The method employed is to excise an eye from any given form and use it as a source of electromotive force in a cir cuit of which the quadrant electrometer is one part. When the eye is inserted into the circuit, light of a definite known wave length is admitted into the eye, and in this way an electromotive force is generated and is indicated by the action of the quadrant electrometer. Wave lengths all the way along the visible spectrum are admitted into the eye, and the concomitant effect noted. The complete study aims to be a record Of such an effect secured from a variety Of animals at different stages of the evolutionary process.
