5 That sight thereof bred cold congealed fear:
That > [So that] congealed > frozen
6 Which to increase, and all at once to kill,
at once > at one time; hence: at a stroke
7 A cloud of smothering smoke and sulphur sere
sere > yellow; or perhaps: searing
8 Out of his stinking gorge forth steamed still,
gorge > throat; maw still > continually
9 That all the air about with smoke and stench did fill.
