On the 8th of December following, Mr. Koenig addressed an advertisement "To the Public" in the columns of The Times, giving an account of the origin and progress of his invention. We have already cited several passages from the statement. After referring to his two last patents, he says: "The machines now printing The Times and Mail are upon the same principle; but they have been contrived for the particular purpose of a newspaper of extensive circulation, where expedition is the great object. "The public are undoubtedly aware, that never, perhaps, was a new invention put to so severe a trial as the present one, by being used on its first public introduction for the printing of newspapers, and will, I trust, be indulgent with respect to the many defects in the performance, though none of them are inherent in the principle of the machine; and we hope, that in less than two months, the whole will be corrected by greater adroitness in the management of it, so far at least as the hurry of newspaper printing will at all admit. "It will appear from the foregoing narrative, that it was incorrectly stated in several newspapers, that I had sold my interest to two other foreigners; my partners in this enterprise being at present two Englishmen, Mr. Bensley and Mr. Taylor; and it is gratifying to my feelings to avail myself of this opportunity to thank those gentlemen publicly for the confidence which they have reposed in me, for the aid of their practical skill, and for the persevering support which they have afforded me in long and very expensive experiments; thus risking their fortunes in the prosecution of my invention. "The first introduction of the invention was considered by some as a difficult and even hazardous step. The Proprietor of The Times having made that his task, the public are aware that it is in good hands." One would think that Koenig would now feel himself in smooth water, and receive a share of the good fortune which he had so laboriously prepared for others. Nothing of the kind! His merits were disputed; his rights were denied; his patents were infringed; and he never received any solid advantages for his invention, until he left the country and took refuge in Germany. It is true, he remained for a few years longer, in charge of the manufactory in Whitecross Street, but they were years to him of trouble and sorrow.
