Such forms are found in various meteorites, sometimes constituting nearly the whole of the mass, sometimes only a small portion of it. This peculiar structure is designated as chondritic, and each individual spherule as a chondrus. Such chondri are usually smaller than a pea. They are generally considered to be drops of matter solidified from a molten condition.
