Tom. 19 p. 73. G. Cuvier remarks that true system of classification depends on taking organs of most influence, or most constant — says that Botanists are obliged to depend on constancy, because use of parts not well known in plants — constancy with zoologists being "moyen subsidiaires." — (I do not agree one iota, high as authority is. Jussieu & MIrbel were right in constancy going with connection of organs.)

Tom. XX. A. Risso Mem. sur l'Hist. des Orangers &c.

p. 188. Correlation "Citrus aurantium fructu variabilis" a var. of common orange, which has the leaves on new shoots rounded-oval "tachetees" spotted with yellow, & borne on petioles with heart-shaped wings; when these are fallen, they are succeeded by leaves more elongated, narrower & undulated, of a pale green "liserées" (bordered?) de jaune, situated on long petioles without wings — The front at first (ie when young) oblong, &c changes in form when ripe & are at first sweet & then become bitter. (The first fact good to quote to show change, from correlation of organization or external causes, & independent of selection &c.)
