adversely eloquent comment on the principles of secrecy and restriction, in any art or science, like photography, which requires the varied suggestions of numerous minds and many years of experiment in different directions before it can be brought to a state of workable certainty and artistic and commercial applicability. Had Reade concealed his success and the nature of his accelerator, Talbot might have been bungling on with modifications of the experiments of Wedgwood and Davy to this day; and had Daguerre not sold the secret of his iodine vapour as a sensitiser, and his accidentally discovered property of mercury as a developer, he might never have got beyond the vapoury images he produced. As it was, Daguerre did little or nothing to improve his process and make it yield the extremely vigorous and beautiful results it did in after years. As in Mr. Reade’s case with the Calotype process, Daguerre threw the ball and others caught it. Daguerre’s advertised improvements of his process were lamentable failures and roundabout ways to obtain sensitive amalgams—exceedingly ingenious, but excessively bungling and impractical. To make the plates more sensitive to light, and, as Daguerre said, obtain pictures of objects in motion and animated scenes, he suggested that the silver plate should first be cleaned and polished in the usual way, then to deposit successively layers of mercury, and gold, and platinum. But the process was so tedious, unworkable, and unsatisfactory, no one ever attempted to employ it either commercially or scientifically. In publishing his first process, with its working details, Daguerre appears to have surrendered all that he knew, and to have been incapable of carrying his discovery to a higher degree of advancement. Without Mr. Goddard’s bromine accelerator and M. Fizeau’s chloride of gold fixer and invigorator, the Daguerreotype would never have been either a commercial success or a permanent production.

      Another important event of this year was the importation of the first photographic lens, camera, &c., into England. These articles were brought from Paris by Sir Hussey Vivian, present M.P. for Glamorganshire (1889). It was the first lot of such articles that the Custom House officers had seen, and they were at a loss to know how to classify it. Finally they passed it under the general head of Optical Instruments. Sir Hussey told me this, himself, several years before he was made a baronet. What changes fifty years have wrought even in the duties of Custom House officers, for the imports and exports of photographic apparatus and materials must now amount to many thousands per annum!

      Having described the conditions and state of progress photography had attained at the time of my first contact with it, I think I may now enter into greater details, and relate my own personal experiences from this period right up to the end of its jubilee celebration.

      I was just fourteen years old when photography was made practicable by the publication of the two processes, one by Daguerre, and the other by Fox Talbot, and when I heard or read of the wonderful discovery I was fired with a desire to obtain a sight of these “sun-pictures,” but the fire was kept smouldering for some time before my desire was gratified. Nothing travelled very fast in those days. Railroads had not long been started, and were not very extensively developed. Telegraphy, by electricity, was almost unknown, and I was a fixture, having just been apprenticed to an engraving firm hundreds of miles from London. But at last I caught sight of one of those marvellous drawings made by the sun in the window of the Post Office of my native town. It was a small Daguerreotype which had been sent there along with a notice that a licence to practise the “art” could be obtained of the patentee. I forget now what amount the patentee demanded for a licence, but I know that at the time referred to it was so far beyond my means and hopes that I never entertained the idea of becoming a licencee. I believe some one in the neighbourhood bought a licence, but either could not or did not make use of it commercially.

      Some time after that, a Miss Wigley, from London, came to the town to practise Daguerreotyping, but she did not remain long, and could not, I think, have made a profitable visit. If so, it could scarcely be wondered at, for the sun-pictures of that period were such thin, shimmering reflections, and distortions of the human face divine, that very few people were impressed either by the process or the newest wonder of the world. At that early period of photography, the plates were so insensitive, the sittings so long, and the conditions so terrible, it was not easy to induce anyone either to undergo the ordeal of sitting, or to pay the sum of twenty-one shillings for a very small and unsatisfactory portrait. In the infancy of the Daguerreotype process, the sitters were all placed out-of-doors, in direct sunshine, which naturally made them screw up or shut their eyes, and every feature glistened, and was painfully revealed. Many amusing stories have been told about the trials, mishaps, and disappointments attending those long and painful sittings, but the best that ever came to my knowledge was the following. In the earliest of the forties, a young lady went a considerable distance, in Yorkshire, to sit to an itinerant Daguerreotypist for her portrait, and, being limited for time, could only give one sitting. She was placed before the camera, the slide drawn, lens uncapped, and requested to sit there until the Daguerreotypist returned. He went away, probably to put his “mercury box” in order, or to have a smoke, for it was irksome—both to sitter and operator—to sit or stand doing nothing during those necessarily long exposures. When the operator returned, after an absence of fifteen or twenty minutes, the lady was sitting where he left her, and appeared glad to be relieved from her constrained position. She departed, and he proceeded with the development of the picture. The plate was examined from time to time, in the usual way, but there was no appearance of the lady. The ground, the wall, and the chair whereon she sat, were all visible, but the image of the lady was not; and the operator was completely puzzled, if not alarmed. He left the lady sitting, and found her sitting when he returned, so he was quite unable to account for her mysterious non-appearance in the picture. The mystery was, however, explained in a few days, when the lady called for her portrait, for she admitted that she got up and walked about as soon as he left her, and only sat down again when she heard him returning. The necessity of remaining before the camera was not recognised by that sitter. I afterwards reversed that result myself by focussing the chair, drawing the slide, uncapping the lens, sitting down, and rising leisurely to cap the lens again, and obtained a good portrait without showing a ghost of the chair or anything else. The foregoing is evidence of the insensitiveness of the plates at that early period of the practice of photography; but that state of inertion did not continue long, for as soon as the accelerating properties of bromine
