there need be no commercial difficulty between the photographer and newspaper proprietor on the score of supply. A multiplication of negatives or Woodbury's process, would afford all the necessary facilities for producing the prints in large numbers. Many new fields for the good of photography are opening up. Pathological works have been photographically illustrated with some amount of success. But far pleasanter fields are open to enterprising photographers in the faithful representation of natural objects, such as flowers, fruits, ferns, grasses, shrubs, trees, shells, seaweeds, birds, butterflies, moths, and every variety of animal life, from the lowest orders to the highest. I believe the time is not far distant when the best works on all the physical sciences will be illustrated by coloured photographs. Those very beautiful German photographs of flowers recently introduced show most conclusively of what photography is capable as a help to a study of the natural sciences. The flowers are not only photographed from nature, but exquisitely coloured after the same fountain of truth; and the sense of reality, roundness, and relief which they convey is truly wonderful. Hitherto the colouring of natural objects photographed from nature has been a very difficult thing to accomplish; but now it is done, and with a marvellous success. The monochromatic process is also making great strides in advance. Those very beautiful transparencies, cabinet size, of the Queen and Royal Family are now to be seen in most of the photographic picture shop-windows in town and country. These transparencies are the productions of the Disderi Company, by Woodbury's photo-relief process, and the results now obtained are really beautiful, both in effect and colour, and sold at a very low price. But the _chef d'oeuvre_ of all monochromatic effects has just been achieved by the triple labours of Mr. Macnee, the artist, and Mr. Annan, the photographer, of Glasgow, and Mr. J. W. Swan, of Newcastle. The subject in question is a work of art in every respect. The original is a full-length portrait of Lord Belhaven, painted by Daniel Macnee, and now in the Royal Academy Exhibition. A photograph taken from the painting by Mr. Annan was worked up in monochrome by the eminent artist, from which another negative was taken by the same skilful photographer, and placed in the hands of Mr. J. W. Swan to be printed in carbon, which the latter gentleman has done in the most admirable manner. Altogether, the result is the most satisfactory reproduction by photography that has ever been placed before the public, and is less like a photograph and more like a fine mezzotint engraving than anything I ever saw. Mr. Annan is now publishing the work on his own responsibility, and a specimen of it can be seen at the offices of "The Autotype Printing and Publishing Co.," 5, Haymarket, London. Mr. Hill, of Edinburgh, is also about to publish, in
