Photo with a microscope attributed to John Marshall as the maker in the front and a microscope made by Giuseppe Campani in the back.
A tiny slice of a dandelion stem under on a petri dish under the lens.
Magnified view of the dandelion stem slice when it was hydrated, showing vibrant greens in coloration.
Magnified view of the dandelion stem slice when it was almost dried, becoming more shriveled in form and brown in coloration.
Back to the #MuseumBoerhaave to work with two rare compound microscopes from the 17th-c., one made by Giuseppe Campani and another attributed to John Marshall as the maker. So many new thoughts emerged from observing how colors and form changed under the lenses. #VisualizingTheUnknown #histsci
