_Second Victim._--Pardon me, Sir, I am not trifling, I have sound reasons for what I say. Your education, Sir, has apparently been neglected. Wait one moment, and I'll give you a new idea, which will contribute materially to your happiness. You will at once admit, I take it, that oxygen and carbonic acid stand at opposite poles in their relations to the respiratory system; also, that said dock-smell was a mixture of carbonic acid of various kinds, and of different degrees of intensity; and, lastly, that animal and vegetable life are complements of each other,--correlatives, so to speak. _First Victim._--Sartin: that's Natur' an' common sense. _Second Victim._--Now, then, plants naturally absorb carbonic acid and give off oxygen during daylight. At night, the process is reversed: then they absorb oxygen and give off carbonic acid. In a similar, but reverse way, man, who was plainly intended to inhale oxygen and exhale carbonic acid in his waking hours, should, in his sleeping hours, in order to be consistent with himself and with Nature, inhale only dense carbonic acid and exhale oxygen. Men and plants make Nature's see-saw: one goes up as the other goes down. Hence it follows as a logical sequence, that the truly wise man, who seeks to comply with the laws of Nature, and to fulfil the great ends of his existence, will choose for his sleeping-apartment the closest quarters possible, and will welcome the fumes which would be noisome by day. For my part, therefore, I feel profoundly grateful even for one night of this little crib. It has already done much for me. I feel confident that it has contributed greatly to my span of life. I am deeply beholden to the owners, to the captain, yea, to all the crew. And for the blessed dock-smell I shall ever be thankful:-- "'T were worth ten years of mortal life, One glance at its array." It will not be amiss to say to you, Mr. Rink, that this theory is sanctioned by one of the leading ornaments of the French Academy. He has advocated it, in an elaborate treatise, with an eloquence and power worthy of its distinguished author. He shows, in passages of singular purity, that beasts, whose instincts teach them far more of the laws of Nature than our reason teaches us, always retire to sleep in a place where they can obtain the closest, healthiest air. In the last communication sent to me on this subject by the learned Professor, he proves conclusively that---- _First Victim._ (His artillery now rumbling down the heights on the full gallop.)--I snum, that's awful! Wal, I never see,--'t beats the Dutch! No kind o' use talkin' with sech a chap. Never see so much nonsense in one head 's that critter's got in his. VIII.--JENTACULAR. A barrow-tone full of groan and creak, trundling along through the well-known bravura commencing,-- "In Koeln, a town of monks and bones," etc.
