Mayo, when he heard their stertorous breathing close at hand, groped for them and shoved tools into their clutch.

There was a dead silence for a few moments, broken only by the stertorous breathing of the man upon the couch.

It, too, was empty, except for a figure breathing with drunken and stertorous stupor in a chair at one corner.
