gators and institütions of learning would henceforth be able to obtain (at a reasonable price) duplicates of whatever originals were in a demand sufficiënt to warrant their reproduction. Such systematic reproduction of unique manuscripts and rare printed works would materially benefit the civilization ,of the future, both because it would disseminate what is now confined in one or two centres of learning, and because it would obviate, through this multiplication of copies, ,the possible loss of scientific and literary material by the destruction in part or whole (as formerly at Alexandria, or recently at Turin and the Vatican) of any ,one of the famous Old World libraries. The possession of one or more facsimiles would also enable the library possessing the original to preserve it from wear and tear"
But it seems that the great difficulties connected with such an enterprise. and the reasons why the first plans of Mr. Hartwig and Mr. du Rieu miscarried,, were not sufficiently known to Mr. Gayley. At least, he did not speak of them. His plans were discussed at the Liège Congress, but this did not lead to any result worth mentioning, in spite of the written recommendation which was given by a scholar of great name and authority, Mr. Sal. Reinach of Paris.
He1) complained very much about the high prices which some publishers ask for reproductions and demanded that the different librarians should co-operate to attain the result that no publication should cost more than 2 francs per leaf („feuillet"). For such' a price many an „avide éditeur" would certainly be willing to work without finantial or other support. At Leyden, at least, the work is done much cheaper. The eleven parts of the Codices which have now appeared in the Leyden enterprise consist of 2598 folios and cost altogether not more than 3569.50 francs; namely :
