sperm

SPERM, n. [L. sperma.]

1. Animal seed; that by which the species is propagated.

2. The head matter of a certain species of whale, called cachalot. It is called by the French blanc de baleine, the white of whales. It is found also in other parts of the body; but it is improperly named, not being a spermatic substance. Of this matter are mad candles of a beautiful white color.

3. Spawn of fishes or frogs.
