The examples had been sent to the Photographic Society with the hope of selling them for the benefit of the widow, but the Society was too wise to invest in such evanescent property. However, a subscription was raised both in England and France for the benefit of the widow and orphans of Niépce de St. Victor. December, 1870, was marked by the death of one of the eminent pioneers of photography. On the 12th, the Rev. J. B. Reade passed away at Bishopsbourne Rectory, Canterbury, in the sixty-ninth year of his age. I have already, I think, established Mr. Reade's claim to the honour of being the first to produce a photographic negative on paper developed with gallic acid, and I regret that I am unable to trace the existence of those two negatives alluded to in Mr. Reade's published letter. Mr. Reade told me himself that he gave those two historic negatives to Dr. Diamond, when Secretary to the Photographic Society, to be lodged with that body for safety, proof, and reference; but they are not now in the possession of the Photographic Society, and what became of them no one knows. Several years ago I caused enquiries to be made, and Dr. Diamond was written to by Mr. H. Baden Pritchard, then Secretary, but Dr. Diamond's reply was to the effect that he had no recollection of them, and that Mr. Reade was given to hallucinations. Considering the positions that Mr. Reade held, both in the world and various learned and scientific societies, I don't think that he could ever have been afflicted with such a mental weakness. He was a clergyman in the Church of England, an amateur astronomer and microscopist, one of the fathers of photography, and a member of Council of the Photographic Society, and President of the Microscopical Society at the time of his death. I had many a conversation with him years ago, and I never detected either weakness or wandering in his mind; therefore I could not doubt the truth of his statement relative to the custodianship of the first paper negative that was taken through the lens of a solar microscope. Mr. Reade was a kind and affable man; and, though a great sufferer on his last bed of sickness, he wrote loving, grateful, and Christian like letters to many of his friends, some of which I have seen, and I have photographed his signature to one of them to attach to his portrait, which I happily possess. In 1871 the coming revolution in photography was faintly heralded by Dr. R. L. Maddox, publishing in the _British Journal of Photography_, "An Experiment with Gelatino-Bromide." Successful as the experiment was it did not lead to any extensive adoption of the process at the time, but it did most unquestionably exhibit the capabilities of gelatino-bromide. As that communication to the _British Journal of Photography_ contained and first made public the working details of a process that was destined to supersede collodion, I will here insert a copy of Dr. Maddox's letter _in extenso_. "An Experiment with Gelatino-Bromide.
