Paper Models of Spheres, M. Schilling No. 43, Carton Ser. No. 7, Cones
notes: label: Description
content: In the nineteenth and early twentieth century, students studying technical subjects often learned about the representation of surfaces by equations in courses in solid analytic geometry. Schools in Europe, the United States, and Japan sometimes purchased models to illustrate such surfaces. The firm of Martin Schilling in Leipzig published these two as part of a series of paper models (the “Carton” series) designed by Alexander Brill and first issued in 1874. Unfolded properly, and placed on a stand, each of the tan models forms a cone. One consists of twenty-six and the other of twenty-four intersecting circles (the two smallest circles are missing from the second model). The lines of intersection and the circles are numbered. The models are stored in light green paper envelopes. A mark on each envelopes reads: Karton-Modelle (/) von Flachen zweiter Ordnung. (/) Nr. 7. (/) Kegel. (/) Verlag von Martin Schilling in Halle a. S. Another mark reads: Leipzig. The envelopes are stored in a black paper box with the other Carton models.
