Conjecture was vain; so after a futile attempt to find additional globules by drilling, the seekers left again with their new specimen—which proved, however, as baffling in the laboratory as its predecessor. Aside from being almost plastic, having heat, magnetism, and slight luminosity, cooling slightly in powerful acids, possessing an unknown spectrum, wasting away in air, and attacking silicon compounds with mutual destruction as a result, it presented no indentifying features whatsoever; and at the end of the tests the college scientists were forced to own that they could not place it. It was nothing of this earth, but a piece of the great outside; and as such dowered with outside properties and obedient to outside laws.
