Research and Writings, 1858 - 1985 May Be Restricted

Series contains the laboratory data and some writings of the DEI Research Division. The series is organized in four groups: laboratory notes, optical measurements of subjects, draft writings, and Professor Charles N. Haskins' calculations. The laboratory notes are the raw and transferred data of experiments on topics such as image asymmetry and stereoscopic vision. The second group, optical measurements, is the raw and finished data of individual test subjects' measurements performed on various optical apparatus such as the horopter and haploscope. The initials of some test subjects are recognizable as DEI staff. The third group is the draft writings of DEI members. Some of the drafts were revised and published. (Publications are cataloged and accessed via the Dartmouth College Library Online System.) Within this material are “chronological files” which are mostly article drafts written by Ames, Bannon and Ogle. The files contain some correspondence, as well. The last section of the series is Professor Charles N. Haskins' calculations in the subjects of binocular perspective and physiological optics.
