Harshaw made no comment as they were shown; they added nothing to what he already knew but did confirm and substantiate.  The ash tray when floating near the ceiling had been out of camera angle, but its leisurely descent and landing had been recorded.  The pistol's image in the:' stereo tank was quite small but, so far as could be seen, the pistol had done just what the box appeared to have done: shrunk away into the far distance without moving.  Since Harshaw had been gripping it tightly when it had shrunk out of his hand, he was satisfied - if "satisfied" was the right word, he added grumpily to himself. "Convinced" at least.
