The Imperial German official paper, the Reiclis An-zeiger, has the following: - " Mr. Wickersheimer, Preparator at the anatomical and zootomical collection of the University of Berlin, has invented a process of preserving corpses, plants and the single parts thereof. He had taken out a patent for the same throughout the German empire, but has given up his rights acquired thereby, thus allowing any person to use his process. It is described in the certificate of patent thus: I prepare the following liquid, in 3000 g. of boiling water, 100 g. of alum, 25 g. of table salt, 12 g. of salt-petre, 60 g. of potash and 10 g. of arsenic acid are dissolved. Let cool and filter. To 10 litres of this neutral, colorless and odorless liquid, add 4 litres of glycerine and one litre of metyl alcohol. Soaking and impregnating are the general ways of application. If preparations, animals, etc., are destined to be kept in a dry state, soak them, according to size, from 6 to 12 days, after that dry them. The ligaments and muscles of bodies, crabs, beetles, etc., will remain soft and flexible, so that their natural motions and functions can be shown on them. If cut, the muscles will work as they do on fresh corpses. No odor of decay.
Worms and insects remain flexible without having their intestines taken out. Small animals and plants, whenever the natural color is desirable to be preserved, must not be dried but kept in the liquid".
