This one has a chook feather study and then some views of a prepared slide of a cross-section of a spinal cord (no doubt some poor wee beastie's) In the bottom left image I adjusted the colour balance in Photoshop to digitally "stain" the image, in the hope of bringing out a bit more detail. The bottom right image is a close-up of the left...you can *almost* see the individual neurons crossing and connecting. Once again, thanks for indulging me! :-)>
