He states that the brain was extracted by poking a hole in the thin bone at the top of the nostrils, the ethmoid bone. A large bronze needle with a hooked or spiral end was used to perform this procedure. However, it has never been clear how such a large organ was removed through such a small hole. It had been speculated that the Egyptians would insert this hook through the nose and the brain could be pulled out in pieces. It proved very difficult to remove using this method. Ronn and Bob improvised. With the corpse lying on its back, they inserted the hook through the nose and managed to pulverize the brain tissue into an almost liquid state. Then they turned the body over onto its stomach, and the liquefied brain tissue drained out through the nostrils. Palm wine and frankincense was used to flush and clean the cranial cavity.
