divining rod

The painting is of a human heart set inside a wind-up music box that has a metal rod poking out of the pulmonary artery.

And there shall come forth a rod out of the root of Jesse, and a flower shall rise up out of his root.

A connecting rod worked a balance-beam, which worked the air-pump, feed-pump, and plug-rod for moving the valves.

A piece of iron sticking out from the cross-head carried the plug-rod for working the gear-handles.

Thereafter we were buffeted like chips in the swirling maw of a whirlpool; we fought our way rod by rod.

This is a minute, slender rod, which lies within and between the pus-corpuscles (Fig. 125), and is negative to Gram's stain.
