Letterheads of the Institut de France featuring Minerva wearing a helmet. -The first letter, addressed to Mr. Dessoye in Toulouse, refers to the upcoming examination to be conducted by four eminent scholars: the chemist Eugène Chevreul, the physicist Becquerel, the chemist and botanist Jean-Baptiste Boussingault, and the botanist and mycologist Camille Montagne (1784–1866), of the work titled “Diseases of Common Plants: Potato, Tomato, Eggplant, Beet, and Others Susceptible to Erisyphes Infection.” Autograph signature and greeting by Flourens. -The second letter, addressed to the botanist and physiologist Charles-Raymond MUSSET (1826–1892), professor at the Faculty of Sciences in Toulouse. LOUIS PASTEUR agrees to attend the experiments [most likely related to panspermia and the origins of microscopic life and spontaneous generation] conducted by Musset: “You have expressed a desire for your experiments to be repeated before a commission of the Academy. For his part, Mr. Pasteur has kindly agreed to this request. A committee has been appointed. This committee invites you to come to Paris to conduct these experiments, which will take place from March 1 to 15 […].” The Academy of Sciences will fund this trip.
