What solution was given,by Good when the chiefs demanded more proofs?

Captain Good gives into his nervous habit of removing his false teeth with his tongue. The Kukuanas see this and are amazed at the sight. Good subtly removes them entirely from his mouth, giving the aggressors a toothless smile to prove that they are gone. He then puts them back in and smiles, convincing them that he can withdraw and grow his teeth at will. The Kukuanas are frightened by this strange man who grows hair on only one side of his face (he had not finished shaving), has a shining eye (the monocle he constantly wears), walks about only in a shirt to show off his white legs, and can remove and regrow his teeth. Quatermain seizes upon this bewilderment to claim that the three white men are indeed spirits from a distant star, and that Umbopa is their servant.
