January 3rd, and has been presented to the Natural History 
Museum, South Kensington. Mr. W. Steuart Menzies 
states that in Moray, he is “now trying to acclimatise 
Norwegian Rype or Willow-Grouse, which, if successful, 
may possibly cross with our ‘red grouse.”’: Quite so: and, 
if he is successful'in the attempt, he may destroy the charac-
