ANNUAL REPORT. 305 Both the President and Prof. Meldola, in proposing a hearty vote of thanks to the lecturer, congratulated him on the valuable results of his patient labours. Prof. Meldola made some extended remarks on the study of the life- histories of insects, which is a field so little explored, but one capable of affording most noteworthy advances in natural history. He also alluded to the curious physical conditions under which aquatic insects lived, such as the assistance to or control over their movements given by the surface-film and to the tremendous internecine warfares in which the insect inhabitants of every pond engaged. He looked upon Mr. Enock's lecture as a really remarkable contribution of Entomological Science. In returning thanks, Mr. Enock gave some hints on methods of working in such observations, and made some amusing remarks illustrative of the long-continued patience often required to achieve such results as those described in his lecture. ANNUAL REPORT OF THE COUNCIL FOR THE YEAR ENDED DECEMBER 31st, 1899. [Read and adopted at the 20th Annual Meeting, postponed (on March 31st) to November 14th, 1900.] The report which the Council has the honour to present to the members may be put into a few paragraphs, as apart from business connected with the Essex Museum of Natural History, the work during 1899 was of a routine character. Finance—The accounts for the year 1899, which are at length laid before you, were audited in May by Messrs. f. D. Cooper and W. Crouch, to whom the Council is much indebted for their services. On comparing these accounts with those for 1898 it will be seen that the debit balance shown on the General Account has been reduced from £43 8s. to £26 9s. 1d. Postage was reduced from £18 0s. 7d. to £15 0s. 3d. It will also be observed that, in accordance with the agreement with the Corporation of West Ham, a sum of £50 (for the year 1899) was transferred to the Museum Maintenance Account. It will further be noted that owing to the satisfactory sales of publications, the long-standing deficiency on that account has been reduced from £25 to £18—in round numbers. The other accounts call for no especial mention until the summary is reached, when it will be seen that the Life Composition Fund was, on December 31st, represented by £57 4s. 8d. in cash, as against £28 13s. 2d. in 1898 ; and that the total deficiency on all accounts had been reduced by a sum of £23 4s. 2d., leaving it at just over £50, an amount which, if the present policy of the Council is adhered to, will soon be eliminated from the accounts. Membership—During the past year 1899 the Club has lost one member by death, thirteen by resignation, and two by removal ; and it has elected twenty-three new members, leaving a nett gain of seven members This brings the total membership, inclusive of Honorary Members and Life- Compounders, up to 296.
