SIXTY YEARS OF BRITISH MYCOLOGY. 223 and what has been accomplished for the microscope and with the microscope during sixty years is a matter of history. As the accurate discrimination of the Cryptogamia depends so largely upon microscopical characters, it is but reasonable to predicate that the knowledge of the Cryptogamia would increase with the development of this agent. As the nineteenth century draws rapidly to its close we who have lived through the last three quarters of it look back with proud satisfaction at all which we have individually been able to do in aid of the onward progress of this department of Natural Science, and, at the same time, look forward with hope and confidence to a glorious future which shall utilize the discoveries of the past. British Mycologists, therefore, have every reason to be satisfied and proud of the progress of mycology in the British Isles during the sixty years reign of the Queen. THE ESSEX FIELD CLUB. VISIT TO THE COLNE ESTUARY, AND INSPEC- TION OF THE COLCHESTER OYSTER FISHERIES AND BREEDING GROUNDS. Thursday, September 9th, 1897. Conductors—The Worshipful the Mayor of Colchester, H. C.

They accordingly formed them- selves into a Committee, and the very successful meeting we have now to record was largely the fruits of their exertions. Many members of the Colchester Corporation took an active interest in the event ; the Colne Fishery Board very kindly lent their steam-dredging vessel, the "Pyefleet," for the occasion, and gave great facilities for the conduct of the meeting, and Messrs. W. and H. A. Cole drew up and illustrated a very handsome circular containing much information on the natural history of the oyster and the mode of culture pursued in the Colne. The threatening skies of the previous days kept some away, and the party was not quite so large as was anticipated, nevertheless about 100 members and friends assembled at Messrs. Forrestt and Sons' ship-yard,
