Durrell is aware that great apes become melancholy if they’re alone in captivity, and worries that N’Pongo will sink into depression if he doesn’t have a companion. It’s notable that when he and Jacquie decide to find N’Pongo a mate, they do so on similar terms as a parent making an arranged marriage for a child. They aren’t just looking for a young female gorilla, but a “wife” for a “husband.” The gorillas don’t have a choice about their future relationship, but Durrell tries to bring them together as compassionately as he can. This seems at odds with his outdated and racist comparison of Nandy’s scar to an “African” hair parting. Although this reference is another moment where Nandy is anthropomorphized, it’s also an offensive comparison, especially as it’s associated with the violence and danger of her capture.
