Report of the Council for the Year 1891. 



The Council of the Hertfordshire Natural Histoiy Society, in 

 presenting the 17th Annual Report, has pleasure in stating that 

 the Society continues vigorous and prosperous, the number of 

 evening meetings held during the year 1891 having been quite up 

 to the average of former years, and on the whole very well at- 

 tended. The field meetings, however, owing to unfavourable 

 weather, have not been quite so numerously attended as usual. 



Diu'ing the year twenty-two ordinary members have been elected, 

 four have resigned, and the Council regrets to have to record the 

 loss of one member by death — Sir James Longden. The number of 

 members at the end of the years 1890 and 1891 was as follows : —
