A NOTE ON THE MARINE ALGAE, ETC. 263 A lecture was then delivered by Mr. Frederick Enock, F.E.S. (Lecturer on Economic Entomology to the Organising Committee of the Essex County Council and Essex Field Club on Technical Instruction) on "The Life-History of the Hessian Fly." The lecture was fully illustrated by some very beautiful slides, prepared from Mr. Enock's original drawings, and exhibited by the oxy- hydrogen lantern. In proposing a vote of thanks to the lecturer, Prof. Meldola alluded to the great value and interest of the original investigations carried on by Mr. Enock on the structure and transformations of this injurious insect, and to the excellent paper on the subject in the "Transactions of the Entomological Society of London." Mr. Meldola stated that it was to be hoped that Mr. Enock would be able to stir up some interest in the important subject of Economic Entomology in Essex now that the Organising Joint Committee had appointed him lecturer on the subject under the scheme of technical instruction now being initiated in the county. The Rev. W. L. Wilson heartily seconded the vote of thanks, which was carried by acclamation. At the conversazione, Mr. W. T. Christian exhibited some fine fossils from various formations, and many interesting objects under his microscope. Tea and coffee were served as usual at the close of the meeting. It was announced that the long-delayed "Part 2 of Vol, iv." of the "Journal of Proceedings of the Essex Field Club" was in the press, and would shortly be ready for publication. It would contain extended reports of all meetings of the Club, from February 23rd, 1884, to January 29th, 1887, after which date reports appeared in the Essex Naturalist. The ''Journal" would be published by subscription, the price to members being probably about 5s. It was also announced that the task of compiling the projected "Bibliography of Essex" (an important work which would be published by subscription as Vol. iii. of the "Special Memoirs" of the Club) was being actively carried on by a representative executive Committee. Those willing to aid the Committee by searching through series of periodicals, etc., should apply to the Secretaries (Mr. E. A. Fitch, "Brick House," Maldon, and Mr. Miller Christy, "Pryors," Broom- field, Chelmsford). Rules, specimen entries, slips, etc., would be sent to workers. A NOTE ON THE MARINE ALGAE AND FLOWERING PLANTS OBSERVED BE- TWEEN HARWICH AND DOVERCOURT. By E. M. HOLMES, F.L.S. ON landing at Harwich from the steamer, after accompanying the members on the excursion on the Orwell and Stour on July 25th, 1891 (see page 247), I found that I had about an hour's spare time before the train would start for London. A ramble along the shore was accordingly undertaken, and the following algae were noticed, the shore on the Dovercourt side of the little breakwater being the richest part.
