The absence of sulphureted hydrogen in samples of unfiltered effluent, which have been kept for about six weeks in stoppered bottles, is also a fact of importance. The settled sewage was not in this condition, as it rapidly underwent putrefaction, even in contact with air, in two or three days.
Accordingly they procured their information most carefully, completed their map, and laid down the reported lake in its supposed position, showing the Nile as both influent and effluent precisely as had been explained by the natives. Speke expressed his conviction that the Luta N'zige must be a second source of the Nile, and that geographers would be dissatisfied that he had not explored it.
The meeting point of these two natures is the mind, the causal nature being influent and the apparent nature being effluent. There are four questions which at once suggest themselves for discussion in connexion with this bifurcation theory of nature. These questions are not really separable. They merely constitute four distinct starting points from which to enter upon the discussion of the theory.
Experiments are being made with more or less promise of success in the direction of the chemical treatment of this liquid so as to purify its effluent water, and retain in a solid form, and in combination with certain valuable added ingredients, all of its undissolved impurities. None of these processes can as yet claim consideration in regulating public works.
It was not necessary to ascend higher, there being nothing about the river itself to repay exploration of it. The question, "Was the Rusizi an effluent or an influent?" was answered for ever. There was now no doubt any more on that point. In size it was not to be compared with the Malagarazi River, neither is it, or can it be, navigable for anything but the smallest canoes.
By this process the soluble organic matter is reduced to a condition favorable to the further and complete purification by natural agencies. "Fourth. The effluent is not liable to secondary putrefaction." Mr.
The results of the first year's efforts were that over two million tons were shipped beyond the Nore, ten thousand tons of floating refuse were cleared away, and the liquid effluent was largely purified.
It seems to me impossible that such happiness can last. 'Faint heart! I chided him. 'It is for you I tremble, he said. 'If if He stopped. 'My darling, forgive me! How I pitied him! How I enveloped him in an effluent sympathy that rushed warm from my heart! He accused himself of having disturbed my existence. Whereas, was it not I who had disturbed his?
The effluent water is not of course chemically pure, but sufficiently so to be turned into any ordinary stream. The second invention rests on a curious fact in chemistry, namely, that caustic soda or potash will absorb steam, forming a compound which has a much higher temperature than the steam absorbed.
He reports as follows: "The reduction of organic matter in solution is the crucial test of the value of a purifying agent, for unless the organic matter is reduced, the effluent will putrefy and rapidly become offensive. "I have not observed in any of the unfiltered effluents from this process which I have examined any signs of putrefaction, but, on the contrary, a tendency to oxidize.
