Human skull and mandible with cut-aways to show the details of nerves and teeth. The label says “George Ashmead, Philadelphia”…there was a druggist listed in Philadelphia by that name from 1875-1892, so it must be from that time period. From the personal collection of Dr. Melton’s Palace of Wonders.

Skulls crusted in salt from Lake Assal, Djibouti. he local vendors find skulls of antelope and camels and put them in the water for a few days and they come out glazed. The salt comes from Lac Assal (Salt Lake), the lowest point in Africa and, at 155 meters below sea level, the third lowest depression on earth. It is the second most salinated lake in the world, after Don Juan Pond in Antarctica.

These gifs depict the moment a mineral forms. Researchers at the Pacific Northwest National Laboratory trained a powerful microscope on the birth of calcium carbonate crystals, a process called nucleation.

To see the unpredictable moment when the seed of a crystal starts rapidly growing, they mixed high concentrations of sodium bicarbonate and calcium chloride in water. They then focused a transmission electron microscope that produces images in real time on the solution.

"This is the first time we have directly visualized the formation process," said materials scientist James De Yoreo. "We observed many pathways happening simultaneously. And they happened randomly. We were never able to predict what was going to come up next."
