First printing of Pasteur's first report on the silkworm disease. Between 1855 and 1865 a widespread epidemic among silk worms called pebrine alarmed the south of France, so much so that finally, in 1865, it drew national attention. In June 1865 the government sent Pasteur down to investigate the disease, and the first report was already finished by the 25th of September, the paper offered.
