PURPOSE:To enable the fixation of almost all kinds of plants in natural state, by immersing a plant in a preliminary hardening liquid and treating the surface of the plant with a hard layer-forming agent. CONSTITUTION:Plant rich in soft tissue, such as whole grass of cresson, flower or sprout of orchids, young leaves of maple, fig, etc., is immersed in a preliminary hardening liquid of a hydrophilic organic solvent such as acetone, methanol, etc., for 5-30min immediately after collection. The immersed plant is surface- treated with a hard-layer forming agent such as cyanoacrylate resin monomer to fix the plant with the synthetic resin. The fixation can be carried out in a short time, i.e. within about 10-40min without impairing the natural beauty of the plant. The process can be applied to small animal, insect, fish or shellfish only by changing the preliminary hardening liquid to a protein-coagulation liquid such as formalin. Especially, the process is effective in preventing the damage of fixed specimen with vermin when applied to the preparation of insect specimen.
