1728 Quotes

Most of his [Euler's] memoirs are contained in the transactions of the Academy of Sciences at St. Petersburg, and in those of the Academy at Berlin. From 1728 to 1783 a large portion of the Petropolitan transactions were filled by his writings. He had engaged to furnish the Petersburg Academy with memoirs in sufficient number to enrich its acts for twenty years a promise more than fulfilled, for down to 1818 [Euler died in 1793] the volumes usually contained one or more papers of his. It has been said that an edition of Euler's complete works would fill 16,000 quarto pages. (Florian Cajori)
The French botanist and chemist Henri-Louis Duhamel de Monceau (1700–1782) identified a fungal disease on the bulbs of saffron crocus (now named Helicobasidium purpureum) and illustrated its sclerotia on the bulbs. His report was read to the Academie royale des Sciences in April 1728; it was "wellconceived, thorough, and conclusive, and led to his election as adjoint chimiste in the same year” (Eklund 1971:223). Duhamel discovered that this fungus spreads underground from one bulb to another. In his Éléments d'agriculture (two volumes, 1762; English edition, 1764), he also accepted insects as a cause of some plant diseases. View quote

During the period in which the theory of phlogiston reached its zenith, four names stand out in bold relief. They are those of Joseph Black (1728–99), Henry Cavendish (1731–1810), Karl Wilhelm Scheele (1742–86), and Joseph Priestley (1733–1804). Of these men the last three were steadfast adherents of the theory, while Black seems to have been indifferent, devoting himself to his researches and placing his own interpretation upon his results.
