There are various types of mummification. Preserving the body by dehydration was known as the "most perfect" method. First the brain is removed through the nose. The skull was then purified with drugs. The internal organs are then removed through an incision in the flank. The abdominal cavity is then cleaned and treated with palm wine, herbs, and spices. The body was then placed in natron for 70 days. This completely dehydrated the body before it was wrapped in linen bandages.
