I will give you an instance.

-- One of these fellows -- a great fighter -- he had fought perhaps forty times, -- he was bragging about it; 'he had fought such one and such one,' he said; -- 'perhaps he ought to have fought Herder, in order to say that he was the best man with the sword of all the German students, -- perhaps he ought to have met Herder, but he didn't care about it!' And a young fellow that heard him, that was by, he took it up; 'Sir,' said he, 'Herder is my friend -- you must fight him -- come to my room to-morrow morning at seven o'clock -- he will meet you;' -- 'very well,' they agree upon the matter togezer.

The next morning he come bouncing into my room at a quarter after seven -- 'Herder! Herder! come on! -- Lessing is waiting to fight you in my room.' -- 'What is the matter ?' -- 'O, Lessing said so and so, and I told him you would fight him at seven, and it is a quarter past' -- 'Well, you tell him I didn't know of this, I am not keeping him waiting; I will come directly.' -- I was not up.

So I got myself dressed, and in ten minutes I was there.

A duel is finished when they have given twelve blows" -- "Twelve on each side, Mr.Herder ?" "Yes -- when they have both of them given twelve blows apiece.
Before we begun, Lessing and me, I whispered to somebody who stood there, that I would not touch him unless he touched me; and then I would give it to him in the ribs.
