Mephistopheles.

My duty I’ll commence without delay,

When with the graduates you dine to-day.

One thing remains!—black upon white

A line or two, to make the bargain tight.

Faust.

A writing, pedant!—hast thou never found

A man whose word was better than his bond?

Is’t not enough that by my spoken word,

Of all I am and shall be thou art lord?
