Model van een hydrostatische pers before 1867

This photograph by F.W. Funckler, taken before 1867, shows a model of a hydrostatic press. The model, made primarily of glass and metal, demonstrates the principles of fluid pressure and the application of force through a hydraulic system. This apparatus would have been used in scientific education to illustrate the fundamental concepts of physics. The image likely comes from a catalog of scientific instruments, highlighting the importance of visual aids in scientific learning.
