Bonnacon and monkeys, (Whole folio) Above, a bonnacon, or aurochs, defends itself against pursuers by emitting a stream of excrement. Below, a tailless monkey carries its twin offspring to escape the hunters. When it tires, it drops the favourite infant from its arms, whilst the less-favoured one continues to cling to its back.
