spherule

The elemental mix in the spherules closely matches that of particles found at two other far-flung sites in Antarctica— one more than 2,750 kilometers away — which suggests that all of the materials originated in the same event.

We recognized that all the oxygen in those spherules is coming from the Earth’s atmosphere.

Considerable areas may sometimes be seen without any yolk-spherule whatever.

What can be more widely contrasted than a newly-born child and the small gelatinous spherule constituting the human ovum?

Lastly, I must tell you about the color of the blue sky which was illustrated by the spherule embedded in an elastic solid.

Imagine the solid to extend miles horizontally and miles down, and imagine this spherule to vibrate up and down.

It is supposed to be of chemical origin, each spherule being an aggregation of particles round a central nucleus.
