The "Tintype" is now being largely practised in America, and is fitted into an envelope or slip, carte-de-visite size. The slip is formed of paper, with an aperture to show the picture, and a flap to fall over it as a protector. I had some of these shown to me a short time ago. The tintype is only another name for the ferrotype or melainotype, which is a collodion positive picture taken on a piece of tin or iron, coated with black japan on the front, and a varnish on the back, to prevent the metal from acting on the bath. The carte-de-visite form of the tintype fitted in the envelope or holder is a very good and ready way of supplying all portraits wanted in a hurry, and its adoption might be found very serviceable to many photographers in England. The American examples that I have seen are very brilliant and beautiful, and, to my mind, next in delicacy of detail and richness of colour to the long discarded but ever beautiful Daguerreotype. I must admit, _en passant_, that the Americans always excelled in producing fine, brilliant Daguerreotypes, and it is much the same with them in the production of glass positives, ferrotypes, or tintypes. The spirit of photography in America and Canada is admirable. Mr. Notman, of Montreal, has long been doing some excellent cabinet pictures representing out-of-door-life, pleasures, and pastimes. Now Mr. Inglis, of Montreal, also produces most beautiful carte-de-visite and cabinet pictures of indoor and out-of-door scenes, such as drawing-rooms, libraries, &c., with suitably arranged and occupied figures in the former, and boating, bathing, and fishing parties in the latter. Some of these pictures have recently been shown to me. They are all very fine examples of photography. The tone and quality of some are beautiful. Many of them are admirably arranged, and exhibit considerable knowledge of composition; but some of them, particularly the interiors, are sadly at fault in their chiaroscuro. They possess no dominant light, or, if they do, it is in the wrong place, leading the eye away from the principal object. In most cases the lights are too scattered, giving a spotty and flickering effect to the picture, which is painful to look at. With his out-of-door scenes Mr. Inglis is more happy, and probably, from his antecedents, more at home. For example, the "Boating Party" is very happily composed, embracing the double form of angular composition--the triangle and the lozenge--and just a little more skill or care would have made it perfect in its lines. The whole scene is well lighted and got up. The boat, foreground of pebbles, stones, shrubs, and trees are all real; the water is represented by tin-foil, wet black oilcloth, or something of the kind, which reflects the forms and colours of objects placed upon or above it. The reflections seem too sharp to be those of water. The plan adopted by Mr. Ross, of Edinburgh, is the best. That gentleman has a large shallow trough fitted up in his studio with
