Hopes readers will send information on the permanence of cross-bred plants and animals. No one doubts that cross-bred productions tend to revert in various degrees to either parent for many generations. But are there not cases of crossed breeds of sheep and pigs that breed true? CD believes occasional cross-breeding of varieties is advantageous in nature as well as under domestication. [See reply to this letter by J. O. Westwood, Gard. Chron. (1860): 122.]
