gives excellent results, and which can be modified with extreme ease, is the following : -

One part of this may be mixed with an equal quantity of stock eikonogen. If development hangs fire at all, or the plate shows signs of under-exposure, add gradually, or drop by drop, watching the action after each addition -
Caustic potash ... ... ...... 120 grs.
Distilled water, to ... ... ... ... 1 oz.
Of the application of eikonogen to lantern and bromide work we cannot speak at present, but in our opinion it is far superior to ferrous oxalate or hydroquinone for this purpose. It is advisable when using eikonogen to employ the acid fixing bath, as obviating all stains, and hardening the film and preventing frills and blisters, which are liable to occur when forcing plates with caustic alkalies.- The superiority of eikonogen over pyro and hydro-quinone is manifest, particularly in developing snap-shot and portrait work, as, no matter how dense the high lights and how weak the shadows, the resulting prints are far softer and more harmonious than would be the case with the other two reducing agents. It gives an image of a bluish black or grey colour, free from any brown tinge, as is the case with pyro, and development has, therefore, to be carried rather farther than old pyro workers are accustomed to.
