THE storage and transfer of aesthetic emotion explain yet another fact, with which indeed I began this little book: namely that the word Beautiful has been extended from whatever is satisfactory in our contemplation of shapes, to a great number of c

"I use a paper prepared with iron sesquioxide rendered sensitive to light by tartaric or, better, citric acid in concentrated solution. This paper, after desiccation and exposure to light, possesses the property of reducing the solution of silver
The Artigues process, so called, is, without any doubt, the best to be employed for the reproduction of plans and drawings in lines. It is simple, expeditious, and yields black impressions on a very pure white ground which are absolutely permanen
The images are veiled. This defect may result from various causes, viz.: 1st. The stock ferric oxalate solution is impaired by a partial reduction of the ferric salt into ferrous oxalate. The solution should be preserved in an o
In all the photographic processes by precipitation of metallic oxides the quality of the paper has a great influence on the results. When the paper is not well sized and not well calendered, the sensitizing solution is absorbed, instead of simply
"A capital process for many purposes," says Mr. Burnett, "is to float or steep the paper in a mixed solution of bichromate of potash and sulphate of copper, as for Hunt's chromotype process.(36) I have mixed gelatine, or occasionally grape sugar,
