Lantern slides (22) of underwater images, diagrams, illustrations and charts, undated

The lantern slides consist of graphs, charts, maps and several bottom photographs, and are numbered MC24-1 through MC21-22 in the lantern slide collection. These slides were likely used by Von Arx for classroom instruction, and many were made from illustrations from his publications. Of the approximately fifty lantern slides that were included in the collection, images identified as illustrating Vox Arx's published papers were removed as were images taken from other published works; images of people, instruments and ships, or images not included in the collection either through his published papers or photograph collection were kept.
