Perspex wings with histology slides. Histology slides are prepared by taking a sample of biological tissue and fixing it to preserve the tissue in as natural a state as possible and prevent postmortem decay. The tissue is immersed in a chemical fixative and then embedded in wax to make it hard enough to cut into very thin sections of tissue (usually 5 to 7 micrometers in thickness). It is then passed through baths of solvents which remove the wax, then through graded alcohols, water and finally through baths of haematoxylin and eosin to stain it for better viewing under a microscope.
