THE ESSEX FIELD CLUB. 95 road, and the party then adjourned to the Ilford schools, where the usual high tea had been arranged in the infants' schoolroom by Mrs. George Ingram, of Ilford. An Ordinary Meeting of the Club (the 139th) was subsequently held in the reading-room adjoining, the new President, Mr. F. Chancellor, in the chair. The following were elected members of the Club : Messrs. Percy G. Powell and R. J. Sheldon. The President announced that the Council had elected Prof. Charles Stewart, M.A., Hunterian Curator at the Royal College of Surgeons, and President of the Linnean Society, as an honorary member, in the place of the late Sir Richard Owen. The President also nominated the following members of the Council to act as his Vice-Presidents during his year of office : Mr. E. N. Buxton, D.L., J.P., &c.; the Right Hon. Lord Rayleigh, F.R.S. ; Mr. Walter Crouch, F.Z.S., and Mr. J. C. Shenstone. A lecture was then given by Colonel C. Swinhoe, MA., F.L.S., F.Z.S., F.E.S., &c, of Oxford, "On Mimicry in Lepidoptera and the Uniformity of Pattern in Protected Species," which was well illustrated by a fine series of slides of mimetic butterflies, shown by the oxy-hydrogen lantern. The lecture was of an exceed- ingly interesting character, touching as it did on phases of biological research and evolution which have only been worked at of late years. The details were naturally of a very technical character, and it would be useless in the absence of figures to attempt any reproduction of Col. Swinhoe's remarks. A vote of thanks was moved by Professor Meldola, in a speech which touched upon many of the points in the lecture, upon which he had himself worked, and this was seconded by Mr. Crouch. Col. Swinhoe briefly replied, and promised to give another lecture to the Club at an early date. Thanks were also voted on the motion of Mr, Crouch to Mr. Ashmole, who had so kindly arranged for the free use of the rooms ; and Mr. Hollington, for permission to visit the camp at Uphall, and the meeting soon afterwards broke up. Field Meeting to Chingford, Bury Wood, Sewardstone, etc. Saturday, May 13th, 1893 (Old May-day). The usual spring forest ramble of the Club was taken on this day, under the leadership of Mr. Walter Crouch, F.Z.S., and Mr. William Cole, F.E.S., and was well attended by a goodly number of members. The programme, which was illustrated by a pretty drawing showing "Seward- stone Meads in May-time," by Mr. Henry A. Cole, announced that the route had been carefully chosen as mostly new ground to the Club ; and in the glorious spring afternoon (it was old May-day) it was especially interesting from the abundance of early flowers and insects. The sky was clear, the air warm, and all damp had disappeared from the forest glades. Insects and caterpillars were abundant, and nets, boxes, and vascula were soon plentifully filled. All along the route the lark and cuckoo's song were heard, whilst the wild flowers added their silent beauty to hedge, ditch, and wayside. But the bloom of the hawthorn had already passed its best, and was fading away.
