I have, throughout, paid attention to plates, both colcured and plain, in the respective works within my research, many of which may be consulted in the Society's library; as I conceive good representations of the objects, as to their forms and appearances in their various stages of growth, must convey much more satisfactory information in this point of view, than any description whatsoever.
