About this work

Description

Polarised light micrograph of a cross section of a cat tongue. This sample is from a vintage prepared slide from the period 1870 - 1905. Blood vessels were injected with dye (iron or silver preparation; black) before fixing and sectioning the tissue in order to visualise the capillaries in the tissue. This was a newly developed technique at that time. The rounded papillae (raised protrusions or bumps on the tongue) at the edge of the tongue can be clearly seen. Horizontal width of image is 3 mm.
