 ... DR. DIAMOND recommends, as the most effectual mode of stopping them, a little gamboge neatly applied with a camel-hair pencil. Where a great intensity is desired, Indian ink may be applied in the same manner, taking care in both cases to smooth off the edges with a dry brush. The cyanide of potassium applied in the same way, but with very great care, will remove the black spots. Before it appears to have quite accomplished its object, a negative should be immersed in water, as ...

... sufficient degree is not altogether satisfactory; but apart from this the necessity of maintaining such low temperatures, far below that of the coldest winter's night, renders the idea wholly inadmissible for all domestic installations. Willgerodt suggested removing sulphuretted hydrogen by means of potassium hydroxide (caustic potash), then absorbing the phosphine in bromine water. For many reasons this process is only practicable in the laboratory. Berge and Reychler proposed extracting both sulphuretted hydrogen and phosphine ...
