of typewriting. Eliminating all purely forensic eloquence and exparte
statements, the addresses of counsel in this celebrated suit are worthy
of deep study by an earnest student, for, taken together, they comprise
the most concise, authentic, and complete history of the prior state of
the art and the development of the incandescent lamp that had been made
up to that time. [22]

[22] The argument on appeal was conducted with the dignity
and decorum that characterize such a proceeding in that
court. There is usually little that savors of humor in the
ordinary conduct of a case of this kind, but in the present
instance a pertinent story was related by Mr. Lowrey, and it
is now reproduced. In the course of his address to the
court, Mr. Lowrey said:

else was not said."

Mr. Duncan--"I got three pages a day out of him, too."

Mr. Lowrey--"Well, it was a good result. It always recalled
to me what I venture now, since my friend breaks in upon me
in this rude manner, to tell the court as well illustrative
of what happened there. It is the story of the pickerel and
the roach. My friend, Professor Von Reisenberg, of the
University of Ghent, pursued a series of investigations into
the capacity of various animals to receive ideas. Among the
rest he put a pickerel into a tank containing water, and
separated across its middle by a transpare
