Playing With Dead Things: The Mummification of Beavis I, Part Four: More of the Same.

The lungs and liver, being the other two organs of ritual significance, got their own box of natron and went the way of the stomach and intestines before them.

I don't remember where we got any of these boxes. Jesus, I hope we don't need them again.

After they're dried, they'll each have their own canopic jar, built to order from red pottery clay. And what's gonna happen to YOUR intestines after you croak, huh?

Urination is strictly forbidden in the fields of Osiris. Probably makes him feel inadequate about his wooden dingdong.

We took this opportunity to clean out the rest of the organs Egypt had decided Beavis wouldn't need. Kidneys, fat bits, spleen-like structures, various glands. After that was over and done with...

Looks pure to me.

...this was all Beavis had left. He'd need it for the scales, of course.

After a bit of a debate, we decided to leave the heart where it was, New Kingdom style, instead of cutting it out and replacing it with a scarab, Old Kingdom style. Beavis is a thoroughly modern rat.

He always hated baths.

A second, equally disturbing antiseptic bath...

Bought this locally. It's one of the very few things I didn't have to ask the Internet for.

...and he's ready to be packed with bundles of natron wrapped in muslin. This muslin. This muslin right here.

Just so you know, the inside of a rat smells like a poorly-ventilated basement. I remembered that smell from high school; I'd dissected a rat in biology class, but assumed at the time that the musty smell was either the result of the preservatives, or a prolonged stay in the school basement, crammed together in their little vats of yellowing alcohol. Guess not.
