Messrs. Bell and Daldy have in preparation a volume of

photographs, chiefly illustrative of places mentioned in the Queen's book. The photographs have been prepared by a process discovered by Mr. Joseph Adam, the specialty of which seems to be this, that it enables the artist to give the full impression of distance. We have seen three of them, and they are really remarkable ; one in particular, a view of Loch Katrine, having a singular softness, as if the artist had been able to photograph the air through which in real life the spectator would be looking. If ever photographers discover the secret of colour, a picture of this kind will beat any water-colour it is possible to paint. The only defect of a photograph like this, as compared with a line engraving, is that it requires a little more careful adjustment of light, but then the actual scene has that defect too.
