Antique Victorian Microscope Slides

Since this was a part of the time period, and is pretty amazing,
here is a peek at a (probably) lost art.

In the 1800's, "exhibition slides were often considered to be the pinnacle of the commercial mounters art, considering the degree of difficulty in their preparation. Combining various objects, often many 100s (or 1000s!) of individual butterfly or insect scales, diatoms, spicules, etc.; each piece was individually selected and assembled to create pictures or complex geometric arrangements."
