success = Erfolg Bateson has “results”, we follow Sherwood; see p. 7, s. 9.

Gärtner Mendel quotes Gärtner quite literally, although quotation marks are missing. Gärtner stated in his book on plant hybrids that he could not agree with “the opinion of those naturalists … who dispute the stability of plant species and assume a continuous progressive development of vegetable species” (mit der Meinung derjenigen Naturforscher […], welche die Stabilität der Pflanzenspecies bestreiten, und eine stäte Fortbildung der Gewächsarten annehmen); see Carl Friedrich Gärtner, Versuche und Beobachtungen über die Bastarderzeugung im Pflanzenreich (Stuttgart: Hering, 1849), p. 475. Gärtner refers to p. 154 of his book for further discussion, where it becomes clear that the naturalists he attacks are “natural-philosphical botanists” (naturphilosophische Botaniker) such as Gottfried Reinhold Treviranus (1776–1837), Franz Joseph Schelver (1778–1832), Heinrich Gottlieb Ludwig Reichenbach (1793–1879), Augustin François César Prouvençal de Saint-Hilaire (1779–1853), Marc-Antoine Puvis de Chavannes (1776–1821), Jean Baptiste Julien d’Omalius d’Halloy (1783–1875) and Isidore Geoffroy Saint-Hilaire (1805–1861); see op. cit., pp. 154–156. Of these, only Treviranus and Isidore Geoffroy St. Hilaire would ring a bell with most historians of the life sciences today. Mendel seems to have relied on Reichenbach’s Flora Germanica (1830–1833) for taxonomic information; see p. 6, s. 15. For some reason, Gärtner abbreviates Reichenbach’s first names as “T. L.” rather than H. G. L., but the title “Hofrath”, as well as the cited article from the journal Isis, edited by the prominent Naturphilosoph Lorenz Oken (1779–1851), reveal his true identity.

progressive development = Fortbildung Bateson and Sherwood have “evolution”. The prefix fort- designates a movement away from something, as in Fortschritt, the German word for “progress”.
