A Bye-meeting was held at Hertford on the 26th of April, and 

 •was devoted to microscopical study and the exhibition of natural- 

 history collections. 



It will thus be seen that the number of papers read during the 

 year is considerably larger than in any previous year, and that a 

 very wide range of subjects has been discussed. 



The reports on the rainfall and on phenological phenomena for 

 1880, the former now drawn up by the Eev. C. W. Harvey, have 

 been published in your ' Transactions,' and to those for 1881, shortly 

 to be presented, will be added a report on injurious insects observed 

 in Hertfordshire, which Miss Ormerod has undertaken in future 

 to present annually to the Society. 



Following a suggestion in the previous report, several members 

 have offered to undertake the duty of recorders in various branches 

 of Natural History. This subdivision of labour will eventually, it 

 is hoped, be productive of good results, especially in the intended 

 compilation of a Cryptogamic Flora of the County, for which re- 

 corders for the Mosses and the Characece are much needed. 



The Council may also suggest the compilation of monographs of 

 the rivers of Hertfordshire, on the model of Mr. Littleboy's " Bul- 

 bome and Gade," as a method of working for the Society which 

 may be undertaken by members who do not make a study of any 

 special branch of Natural History. 



An unusually large number of Field Meetings has been held 

 during the year, in fact about twice the average number of former 

 years. The following are the dates of these meetings and the 

 localities visited : — 



May 7. — The Bourne Valley, Boxmoor. 



12. — Broxbourne and Brickendon. 



19. — Buntingford. 



28. — Stanmore Common. 



June 2. — Panshanger, Hertford. 



8.— Munden Park, Watford. 



18. — Hoddesdon. 



25. — Totternhoe, Kensworth, and Luton. 



July 9. — Hunton Bridge and Watford. 

 21. — Epping Forest.
