Brown (cheerfully). With the assistance of the Public Press, to be sure I can. See here, I will give you the solution to the problem, as told by the Journals, "without puzzling technicalities."
Jones. I hang upon your words with an impatience that politeness—the outcome of civilisation—alone renders endurable.
Brown. Then you must know that Dr. KOCH has discovered that the remedy for tuberculosis consists of a glycerine extract of a pure cultivation of tubercle bacilli, the local effect of which, when injected into a healthy guinea-pig, produces a nodule found at the point of inoculation, which, when a second puncture is perpetrated, causes what may be called the bacillary fluid to be brought into the current of its circulation, so that the infected tissue may react upon the agent which it had previously been able to resist. I am not quite sure that I have got the exact words, but that's the idea. Simple, isn't it?
Jones. Very! [Exeunt severally.
