Great colour and clarity in those images, cell walls looks like glass!

Hi Seb,

great images, and what a nice place to collect the material!

What means "flèche de Mathias"?

Interesting to see this Matthias arrow in use.
He did some interesting stuff nearly 20 years ago but it was never recognized very much.

Vivid. It's like I'm looking down the EP on them. Nice work.

Great images! The first image with fleche de Mathias illumination looks almost like some of the enhanced contrast techniques used on modern microscopes, and the arrow can be used with a simple instrument equipped with just a basic Abbe condenser.
