Louis Jacques Maude Daguerre, whose name is for ever associated with the photographic process, of which he was the discoverer, died on the tenth of July, in Paris, in the sixty-second year of his age. He was a man of extreme modesty and great personal worth, and was devoted to art. He was favorably known to the world before the announcement of his discovery of the Daguerreotype. His attempts to improve panoramic painting, and the production of dioramic effects, were crowned with the most eminent success. Among his pictures, which attracted much attention at the time of their exhibition were, The Midnight Mass, Land-slip in the Valley of Goldau, The Temple of Solomon, and The Cathedral of Sainte Marie de Montreal. In these the alternate effects of night and day, and storm and sunshine, were beautifully produced. To these effects of light were added others, from the decomposition of form, by means of which, for example, in The Midnight Mass, figures appeared where the spectators had just beheld seats, altars, &c., and again, as in The Valley of Goldau, in which rocks tumbling from the mountains replaced the prospect of a smiling valley. The methods adopted in these pictures were published at the same time with the process of the Daguerreotype, by order of the French Government, who awarded an annual pension of ten thousand francs to Daguerre and M. Niepce, jr., whose father had contributed towards the discovery of the Daguerreotype. Daguerre was led to experiments on chemical changes by solar radiations, with the hope of being able to apply the phenomena to the production of effects in his dioramic paintings. As the question of the part taken by him in the process to which he has given his name, has been discussed sometimes to his disadvantage, it appears important that his position should be correctly determined. In 1802, Wedgwood, of Etruria, the celebrated potter, made the first recorded experiments in photography; and these, with some additional ones by Sir Humphrey Davy, were published in the journals of the royal institution. In 1814, Mr. Joseph Nicephore Niepce was engaged in experiments to determine the possibility of fixing the images obtained in the camera obscura; but there does not appear any evidence of publication of any kind previously to 1827, when Niepce was in England. He there wrote several letters to Mr. Bauer, the microscopic observer, which are preserved and printed in Hunt's _Researches on Light_. He also sent specimens of results obtained to the Royal Society, and furnished some to the cabinets of the curious, a few of which are yet in existence. These were pictures on metallic plates covered with a fine film of resin. In 1824 Daguerre commenced his researches, starting at that point at which Wedgwood left the process. He soon abandoned the employment of the nitrate and chloride of silver, and proceeded with his inquiry, using plates of metal and glass to receive his sensitive coatings. In 1829 M. Vincent Chevalier
