54 Infusoria: What are they ? It may be finally submitted that no complete Infusorial Fauna of any one district in the United Kingdom has, up to the present time, been placed on record, and that it lies in the power of the members of a Naturalists' Field Club so favourably located as the one I now address to not only secure for themselves and their fellow-members an in- exhaustible fund of instruction and recreation by a pains- taking investigation of the Infusoria distributed throughout the Forest districts or the wider field of the County at large, but by following out such a study, systematically and faith- fully, they may materially benefit and advance the cause of Science in connection with a field of research having, as so far explored, a literally limitless horizon, and where it may advisedly be said, "the harvest truly is plenteous, but the labourers are few."
