Pretty big doctors, I learned later, all of them from Boston.

They had taken a cadaver from the refrigerator and stood it in a certain position.

Then the one man had struck it on the head with the mallet with all the force he could summon.

Of course it knocked the corpse down--I'm telling you, it was gruesome, even to an interne! The last I saw of them, the doctors were working with their microscopes--evidently to see what effect the blow had produced." "What was the idea ?" "Never found out.

They're pretty close-mouthed about that sort of thing.
You see, opposite sides in a trial are always carrying out experiments and trying their level best to keep the other fellow from knowing what's going on.
