I have sub mitted to the paper manufacturer all of the plants, the lurks the common vegetables, and the papers that are at the back o volume are the results of my experiences. I wish to prov these materials may be substituted for \h: usual papcnmkm terials, which become rarer each da ay an thi tha ma u have been the first Monsieur, to appreciate the ;\dv:m('\ge of s discovery and I emPlore you to permit me to show the public the results of m knowledge." Delisle had i prccukd by Dr. Schiffer in the us of materials to replace rags for papermaking, but the specimen made by Schiffer were fabricated with an admixture of linen an cotton. Delisle, however, used nothing but the fibres of the plant in the making of his paper and he therefore claimed greater accomplishments than his predecessor. The question was carried before the Académic des Sciences and a report relating to \hc wor of the two scientists was presented on November 18, 1786. Thi report was signed by Berthollet, Lavoisier et Sage and s(:\md tha the papers of Delisle contained almost no linen or cotton whil those of Dr. Schiiffer contained considerable rag fibre.
