MANY of our readers will, no doubt, entertain the belief that the proposal to establish a Museum of Pure and Applied Science, to include what is known as the Patent Museum, recently laid before the Duke of Richmond and Gordon by the President of the Royal Society and other distinguished men of science, has been a thing of sudden growth. Some justification for such a belief may seem to be derived from the Loan Collection of Scientific Apparatus now being exhibited at South Kensington, and many of those who have witnessed its success would like to see it developed into a permanent institution. No doubt, this Collection has helped to bring into practical shape the desire which for years many men of science in this country have possessed of seeing this country possessed of an institution similar to the Paris Conservatoire des Arts et Métiers, which desire has at last taken the form of the all but unanimous memorial on the subject which was recently presented to the Lord-President of the Council, and which we published in a recent number. But the truth is that this memorial is strictly in accordance with an official, recommendation made to the Earl of Granville, then Lord-President of the Council, as far back as the year 1865. At that time the Secretary of the Science and Art Department and Director of the South Kensington Museum, Mr. (now Sir) Henry Cole, along with the late Capt. Fowke, were instructed by the Lord-President to proceed to Paris and report upon the relations between the Conservatoire des Arts et Métiers and the French Patent system.
