- f2 5040.f2See letter from Albert Müller, 28 March 1866 and nn. 2 and 3.
- f3 5040.f3CD's discussion of slave-making by Formica sanguinea and other ant species in Origin, pp. 219--24, was based primarily on observations made by him and the entomologist Frederick Smith in Britain (see Correspondence vols. 7 and 8). CD's observations of slave-making ants, made between 1858 and 1860, are in DAR 205.11: 88--107. CD's information on F. sanguinea in Switzerland was based on Huber 1810.
- f4 5040.f4In Origin, p. 221, CD stated: `I observed a few slaves mingled with their masters leaving the nest, and marching along the same road to a tall Scotch-fir-tree … which they ascended together, probably in search of aphides or cocci.' This passage was unaltered in subsequent editions.
