My post two years ago on the possible existence of the thylacine, or Tasmanian tiger in the Indonesian half of New Guinea appears to have been extremely popular, and is still attracting comments. So I think it is about time I updated it with evidence from a correspondent called Franz. He has asked me not to publish his last name, but he lives in Vienna, Austria, and has visited the country often for reasons unconnected with his career as a graphic designer. He usually travels with a doctor friend.
