I pull out the leg of a live Spider and put it to soak for an hour in disulphide of carbon, which dissolves fat.
The disulphide, IrS2, is formed when powdered iridium is heated with sulphur and an alkaline carbonate.
I put the leg to soak for a quarter of an hour in disulphide of carbon, the best solvent of fatty matters.
By heating the disulphide in a current of hydrogen, germanious sulphide, GeS, is formed.
