Sometimes spectators of these duels faint--and it does seem a very reasonable thing to do, too.
Both parties to this fourth duel were badly hurt so much that the surgeon was at work upon them nearly or quite an hour--a fact which is suggestive.

But this waiting interval was not wasted in idleness by the assembled students.

It was past noon, therefore they ordered their landlord, downstairs, to send up hot beefsteaks, chickens, and such things, and these they ate, sitting comfortable at the several tables, whilst they chatted, disputed and laughed.

The door to the surgeon's room stood open, meantime, but the cutting, sewing, splicing, and bandaging going on in there in plain view did not seem to disturb anyone's appetite.

I went in and saw the surgeon labor awhile, but could not enjoy; it was much less trying to see the wounds given and received than to see them mended; the stir and turmoil, and the music of the steel, were wanting here--one's nerves were wrung by this grisly spectacle, whilst the duel's compensating pleasurable thrill was lacking.
Finally the doctor finished, and the men who were to fight the closing battle of the day came forth.
