13 Apart from the obvious advantages of having in one build- ing our collections, library, and meeting-room, and of leading an independent instead of a parasitical existence, the forma- tion of a permanent museum would, I am convinced, promote our objects in many other ways. Our "Biological Registry Office" would become better known throughout the county, and useful specimens which by accident might fall into the hands of the non-scientific would naturally be sent to our museum. Then the large number of species which would have at first to be collected would lead our active workers to co-operate for a common object—the formation of a typical collection representing the natural history of the county. In this undertaking our would-be beginners might well take a part, and in so doing would commence to derive those educa- tional advantages arising from the study of field zoology and botany to which I have already referred. It will be far more satisfactory to have a general collection formed in all parts of the county by our own members for the express purpose of being deposited in our cabinets than to exhibit the "tag, rag, and bobtail" of old collections, or to expose to public view the faded and dilapidated specimens to be seen in many local museums, both at home and abroad, the authorities of which should regard their tattered posses- sions with much the same feelings as did Sir John Falstaff his ragged regiment. In addition to collections of species illus- trating the actual productions of our district, it would be most especially desirable in the case of insects to have preparations showing the life-history at every stage of transformation, and dissected specimens illustrating the structure and anatomy. In time we might thus come to possess a collection both of educational and technical value that would not be unworthy of a Field Club which already includes members of many of the most influential families in the county, and which might ultimately become of scientific use to specialists outside our own ranks—"a consummation devoutly to be wished." The geological features of the County of Essex have been
