Bf JOSEPH WEIGHT. 239 



engaged in the duties of his profession (a profession which at one 

 time took him to North America, at another to South America, 

 and to Siberia), he could not take any active part in the work 

 of the Club, which undoubtedly he would have done had he 

 lived among us. Yet he took a warm interest in its welfare, 

 and was always glad to hear of its progress. Our local ]^a- 

 tural History may have lost somewhat by his long absence, but 

 that of the world at large has the more benefited by his labours, 

 and he adds another blight name to the roll of those who have 

 so well upheld the JS'atural History fame of our district.
