THE PRESIDENTIAL ADDRESS. 97 I should like here to point out that the zeal of our colleagues might often be much better directed, if they could easily ascertain what is already known of the natural productions of the county, and I trust that every capable working member in each department will aid in putting this kind of information before our Club. Even small beginnings in this direction, if they be but exhaustive, would be of great benefit, as showing, at least, how much remains to be done. When once a list of the known species of any group or branch is brought up to date, however imperfect it may be as regards the actual numbers, it affords a starting point for further research; there is great pleasure in being able to add to its completeness, and an incentive to renewed work is thereby given to the collector and student. There may be some members who for various reasons cannot use the gun, the net, the vasculum or the geologic hammer in the field, and may be debarred from an attendance at our meetings (non omnia possumus omnes) and to these especially I commend these last remarks. Such members can dig into books, and wade through newspapers, serials, and museum catalogues. If they will only rediscover for us and note down the facts which were once recorded by the old writers, the curious student, by the dry systematist, or even by the practical man, without knowing or anticipating their future importance or local interest—such workers will be doing their part towards furthering the objects of the Club in gaining a full knowledge of the natural and artificial features of our county. Our publications are but a means to an end in which there is no finality, and much has been written from Aristotle, the great father of all natural knowledge, to the immortal Linnaeus, and onwards, which as yet has by no means received its full attention. It has been truly and happily said, I believe by one of our members, that "it is one of the paradoxes of modern days that we get better acquainted with antiquity as we reach farther from it. The printing press has made all discoveries cumulative. Especially in this the case with regard to recent attainments in prehistoric lore" ("Leisure Hour," 1868, p. 517). I do not wish that our publications should be a mere dry accumu- lation of already recorded facts, inasmuch as the investigation of the natural history, topography, and pre-historic remains of Essex affords a fine field for the exercise of the observing and reflective faculties; still it must be a great advantage to have collected together what
