8 the year, mysteriously disappears for the remainder; and that the strictest police supervision should entail on. all insects whose purposes or habits are unknown." When we look at the numerous woodland patches scattered throughout the County of Essex, we can entertain no doubt but that our district was originally covered with forest. It is recorded that in the reign of Henry III. a royal forest extended right across the county in a north-easterly direction from Stratford Bridge to Manningtree. In the reign of Charles I. the great Waltham Forest comprised Epping and the now almost extinct Hainhault Forests, thus forming a large woodland area bounded to the east by the River Roding, to the west by the River Lea, to the south by the great Chelmsford and Colchester road, and stretching northwards for sixteen miles as far as Roydon, almost on the boundary of the county. Thus, as might have been anticipated, our district is especially rich in woodland species. Epping Forest itself, so far as my own experience goes, certainly does not appear to be so productive from a collecting point of view as some of the woods of Kent and Surrey to the South of Lon- don ; but our county, taken as a whole, has furnished many rarities. We shall hope in the course of time to be in a posi- tion to furnish local catalogues of animals and plants, for the preparation of which we shall look to our ornithologists, botanists, entomologists, microscopists, &c. I do not propose on the present occasion to enter into much detail respecting the natural productions of our district, as I should thus only have to tax your patience with a long list of specific names ; but I will restrict myself to a few general remarks. Mr. Edward Newman has given the names of seven species of bats* as being found in the Forest; and with regard to birds, Mr. James English, one of our members, whose name as a collector was long associated with that of the late Henry Doubleday of Epping, has recorded about 120 species,* 20 of which are occasional visitors driven into the Forest by stress of weather or other causes.
