ABSTRACT
Although the daguerreotype has hardly been in existence for four years, it already ranks as one of the most prominent inventions of the present day, leaving scarcely any thing to look for in the way of improvement. It is true that it remains to find the means of reproducing the natural colours of objects. Although there seems no dream too marvellous in the progress of discovery, still the idea of fixing the colours of the object in the camera obscura is so little in accordance with the present state of science and with the properties of the known elements, that one must be satisfied with the process as it is.
