Unity author Imelda Octavia Shanklin referred to their case in her 1929 book, "What Are You?": "I once heard a missionary tell of seeing two girls who had been rescued from a den of wolves in Asia. As babes they had been abandoned, and, in a measure duplicating the young lives of Romulus and Remus, had been mothered by a female wolf. The children ran fleetly on all fours; they snarled and bit at their captors. The forehead retreated, the lower face protruded in unmistakable likeness to the foster-parent beast that had shown them more of mother love than their human mothers had shown."
