The liver cells are seen to contain a large globule of fat which pushes the cell nucleus to one side - giving the signet-ring appearance.
The heat is sufficient to keep the resulting lead oxide fused, and the porous cupel has the property of absorbing melted lead oxide without taking up any of the metallic globule, exactly in the same way that blottingpaper will absorb water whilst it will not touch a globule of mercury.
I can trace my family back to a protoplasmal primordial atomic globule.
The remaining litharge was absorbed by the porous cupel, leaving a globule of metallic silver about 99.9% pure.
Each female can produce up to half a million tiny eggs, each containing a globule of oil that makes the egg buoyant.
