Worse than those who want to collect gorillas for their private zoos are those who just want to collect bits of gorillas. For many years there was a brisk trade in skulls and hands that were sold to tourists and expatriates who mistakenly thought they would look finer on their mantelpieces than they did on the original gorilla. This, thank goodness, is also now declining, since a taste for bone-headed brutality is now held to be less of a social grace than formerly.
