Canopic jars were used to house the internal organs of the deceased. Each jar was protected by a god and displayed on the jar lid, one of the four sons of Horus. Hapi (ape headed) for the lungs, Imsety (human headed) for the liver, Duamutef (jackal headed) for the stomach and Qebsenuef (falcon headed) for the intestines. This particular jar underwent scientific testing in 2004 and apparently it still contained traces of the spices and resins used on the organs as well as and traces of the organs themselves.In 2004 Doctor Stephen Buckley ,then of The University of York, performed gas chromatography & mass spectrometry upon the jar's contents. The university's testing revealed organs had been coated in a blend of conifer (cedar) resin and pistacia resin. The tests also indicated the jar had contained alcohol, specifically date palm wine which has antiseptic properties and was used to preserve the body and entrails. Testing also revealed the presence of an aromatic spice, most likely cinnamon or cassia.Following more recent research work on human remains from Yemen,York were were able to narrow down the specific organ contained in Djedifankh's jar.By examining the presence of key acids (eg. bile acids),the researchers were able to work out the original type of animal headed jar lid.The result of the key acid analysis showed the presence of human bile. This indicates that the jar was used for the stomach. So originally the jar would have had a lid with the head of Duamutef, the jackal-headed god.
