But how these phantom figures vanished! How rapidly they changed from ghostly and almost invisible shadows to solid, visible, and all but tangible forms under the magical influence of Goddard's and Claudet's "bromine accelerator," and Fizeau's "fixing" or gilding process! How Mercury flew to the lovely and joint creations of chemistry and optics, and took kindly to the timid, hiding beauties of Iodine, Bromine, Silver, and Light, and brought them out, and showed them to the world, proudly, as "things of beauty," and "a joy for ever!" How Mercury clung to these latent beauties, and "developed" their charms, and became "attached" to them, and almost immovable; and consented, at last, to be tinted like a Gibson's Venus to enhance the charms and witcheries of his protégés! Anon was Mercury driven from Beauty's fair domain, and bright shining Silver, in another form, took up with two fuming, puffy fellows, who styled themselves Ether and Alcohol, with a villainous taint of methyl and something very much akin to gunpowder running through their veins. A most abominable compound they were, and some of the vilest of the vile were among their progeny; indeed, they were all a "hard lot," for I don't know how many rods--I may say tons--of iron had to be used before they could be brought into the civilized world at all. But, happily, they had a short life. Now they have almost passed away from off the face of the earth, and it is to be hoped that the place that knew them once will know them no more; for they were a dangerous set--fragile in substance, frightful abortions, and an incubus on the fair fame of photography. They bathed in the foulest of baths, and what served for one served for all. The poisonous and disgusting fluid was used over and over again. Loathsome and pestiferous vapours hovered about them, and they took up their abode in the back slums of our cities, and herded with the multitude, and a vast majority of them were not worth the consideration of the most callous officer of the sanitary commission. Everything that breathes the breath of life has its moments of agony, and these were the throes that agonised Photography in that fell epoch of her history. From the ashes of this burning shame Photography arose, Phoenix-like, and with Silver, seven times purified, took her ethereal form into the hearts and _ateliers_ of artists, who welcomed her sunny presence in their abodes of refinement and taste. They treated her kindly and considerately, and lovingly placed her in her proper sphere; and, by their kind and delicate treatment, made her forget the miseries of her degradation and the agonies of her travail. Then art aided photography and photography aided art, and the happy, delightful reciprocity has brought down showers of golden rain amidst the sunshine of prosperity to thousands who follow with love and devotion the chastened and purified form of Photography, accompanied in all her thoughts and doings by her elder sister--Art.
