Abstract
BOTH these volumes are by “practical men,” and they are characterised to the full, if we may say so, by the advantages and the disadvantages that might be expected to result from this fact. Each has a critical and, to a certain extent, supplementary introduction by Mr. W. Gamble, so that the reader may feel fully assured that he is in safe hands, (i) Mr. Horgan goes clearly and concisely over the subject as he has practised it, and as he is a man of great and prolonged experience, his instructions cannot fail to be of value to the student, whether or not he has arrived at the stage of workman. But it is not a treatise on the subject. The author leaves theory quite on one side, though here and there he justifies his directions by a shrewd statement of the trouble likely to follow variations of them. Perhaps the chief matter to notice is that Mr. Horgan uses collodion, while in this country gelatine plates have largely replaced it.
