caption: The image shows a black and white drawing of a building with a diagram of a machine in the center. At the bottom of the image, there is some text which reads "mineralogic salines". The machine appears to be a large, cylindrical object with a handle on one side and a nozzle on the other. It has a long, thin metal frame with a curved top and a flat bottom. The text is written in a bold, black font and is surrounded by a white border.
