Frina , the Orangoutang , makes a tender nurse . The two ' stars ' of the Moscow Zoo are Frine , an orang outing , and Liza , a chimpanzee . Frina ' s consuming passion is for dolls . There is one in particular on which she lavishes a mother ' s care and can usually be seen nursing with great tenderness . Liza is a perfect lady always . Even when there are no interested Muscovites peering into her cage , she refuses to eat or drink unless she is protected by her bib and is provded with proper plates , spoons and glasses . Photo shows , Frine the orang outang , takes on a soulful aspect as she nurses her favourite doll . 20 November 1935
