TitleUnpublished paper, 'On various phenomena of refraction through semi-lenses or prisms producing anomalies in the illusion of stereoscopic images' by Antoine Claudet
DescriptionHaving observed that photographic pictures representing flat surfaces when examined in the refracting stereoscope have the appearance of concavity, Claudet has endeavoured to discover the cause of this phenomenon, and to explain it. In order to ascertain if this peculiar effect can be attributable to some imperfection in the lenses of the camera obscura which had produced the photographic pictures, or to a property of the stereoscope itself, he tests the stereoscope without photographic images. For this experiment he places under each tube of the stereoscope a diagram composed of vertical and horizontal lines crossing each other. He describes his experimental results.

Includes 23 figures in the text. Annotations in pencil.
