I have some additional information about the word Przewalski; I had no idea it could be the name of a man as well, so I learnt something new today, John. When I was a student at the vet. school, we had to learn about horse races (not racing), and we were told that the Norwegian national horse, the fjord horse, was genetically close to the Przewalski horse ( Equus ferus przewalskii), a rare and endangered wild horse native to Mongolia. The fjord horse has some characteristic colouring: a dark stripe in the center of the mane and dark ‘grips’ on the legs, just like the wild horse, otherwise they are all dun coloured. I would never have remembered these details if it hadn’t been for that difficult name which was so difficult to pronounce.
