To the bii-ds in the jSleteorolog-ical Society's list three species 

 have been added since our last report was cbawn up, in fact in the 

 present year (1882), so that the number of insects and birds, etc., 

 to be observed is now 29. Of the 26 species in the former list 

 adopted by our Society, 23 have been observed during the year, a 

 larger number than in any previous year. In the following table 

 the earliest of these dates is in each case alone given. For details 

 of observations of the insects reference must be made to the report 

 by Miss Ormerod,*' and of the birds to that by Mr. Littleboy.f 



Observations of frog-spawn only remain to be recorded. This 

 was seen at Redbourn Bury, St. Albans, and at Hertfoid, on the 

 12th of March, at Hoddesdon on the 18th, and at Fanhams Hall, 

 Ware, on the 19th.

Phenological observations have now been carried on in Hertford- 

 shire for six years, and nearly half the species in the Meteorological 

 Society's list have been observed every year of the six. A table 

 showing the mean date of the earliest observations in each year for 

 the first three years was given with the report for 1878,| and a 

 table for the six years, 1876-81, accompanies the present report 

 (pp. 76, 77). As in the previous table the phenomena are entered 

 in the order of the mean date of their occurrence, the number of 

 years from which this mean date is derived being entered in a 

 column preceding that of the dates. It will be seen that 44 of the 

 phenomena selected for observation have been observed six years, 

 17 five years, 18 four years, 4 three years, 11 two years, and 3 one 

 year, and that only 3 have not been observed at all.
