[21] See some remarks on this head with respect to sheep by Mr. Wilson, in ‘Gardener’s Chronicle,’ 1863, p. 15. Many striking instances of this result are given by M. Malingié-Nouel (‘Journ. R. Agricult. Soc.,’ vol. xiv. 1853, p. 220) with respect to crosses between English and French sheep. He found that he obtained the desired influence of the English breeds by crossing intentionally mongrelised French breeds with pure English breeds.
