We have learned many curious facts from photographic portraits which we were slow to learn from faces. One is the great number of aspects belonging to each countenance with which we are familiar. Sometimes, in looking at a portrait, it seems to us that this is just the face we know, and that it is always thus. But again another view shows us a wholly different aspect, and yet as absolutely characteristic as the first; and a third and a fourth convince us that our friend was not one, but many, in outward appearance, as in the mental and emotional shapes by which his inner nature made itself known to us. Another point which must have struck everybody who has studied photographic portraits is the family likeness that shows itself throughout a whole wide connection. We notice it more readily than in life, from the fact that we bring many of these family-portraits together and study them more at our ease. There is something in the face that corresponds to _tone_ in the voice,--recognizable, not capable of description; and this kind of resemblance in the faces of kindred we may observe, though the features are unlike. But the features themselves are wonderfully tenacious of their old patterns. The Prince of Wales is getting to look like George III. We noticed it when he was in this country; we see it more plainly in his recent photographs. Governor Endicott's features have come straight down to some of his descendants in the present day. There is a dimpled chin which runs through one family connection we have studied, and a certain form of lip which belongs to another. As our _cheval de bataille_ stands ready saddled and bridled for us just now, we must indulge ourselves in mounting him for a brief excursion. This is a story we have told so often that we should begin to doubt it but for the fact that we have before us the written statement of the person who was its subject. His professor, who did not know his name or anything about him, stopped him one day after lecture and asked him if he was not a relation of Mr. ----, a person of some note in Essex County.--Not that he had ever heard of.--The professor thought he must be,--would he inquire?--Two or three days afterwards, having made inquiries at his home in Middlesex County, he reported that an elder member of the family informed him that Mr. ----'s great-grandfather on his mother's side and his own great-grandfather on his father's side were own cousins. The whole class of facts, of which this seems to us too singular an instance to be lost, is forcing itself into notice, with new strength of evidence, through the galleries of photographic family-portraits which are making everywhere. In the course of a certain number of years there will have been developed some new physiognomical results, which will prove of extreme interest to the physiologist and the moralist. They will take time; for, to bring some of them out fully, a generation must be followed from its cradle to its grave.
