Léonce Élie de Beaumont (1798-1874), geologist. 3 L.A.S. and 1 L.S. to geologist Félix de Francq. Paris, 1853-1858 and undated. 10 pp. in-4 and in-8, one at the heading of the Academy of Sciences. Nice correspondence on the earth arc theories of Félix de Francq. He sends him some proofs "so that you can eliminate some printing errors []. I draw your attention to the 2 and 4 in the table which seem to me to be mistakes. I put my visa on and I promised the Bachelier's printing house, rue du Jardinet n°12, that the proof would be sent back tomorrow morning". He hopes to go and see him soon in Dyck and do some geological races with him. "I read with great interest everything you were kind enough to write to me about the 50 new circles whose submerged and emerged parts you have still measured. These measurements confirm on a large scale the law which you made known in the brief you read at the academy, and you seem to me to possess already the elements of a very important addition to that brief; but perhaps you will gather an even greater number by measuring the arches which are increasingly inclined at the equator until they reach the polar regions. Like you, I saw with great pleasure the appointment of Mr. d'Orbigny to a chair of Paleontology and I am very grateful to Mr. Fourtoul for this. On behalf of the Academy of Sciences, he acknowledges receipt of his third handwritten dissertation "De la formation et de la répartition des reliefs terrestres", which will be analysed by Dufrénoy, Senarmont and himself. In a last long letter (4 pp. in-4), he comments on his 4th thesis which he presented to the academy in the session of March 15; he explains the procedure within the commission for its approval and printing. "Your globe, your instruments and your small demonstration devices are still in my office at the Institute, ready to be placed before the commission.
