More forms were found, but could not be determined by me. This list will
give an idea of the variety of forms to be met with in the hunt for ague
plants; still, they are as well marked in their physical characters as a
potato is among the objects of nature. Although I know you are perfectly
familiar with algae, still, to make my report more complete, in case you
should see fit to have it pass out of your hands to others, allow me
to give a short account of the Order Three of Algae, namely, the
Chlorosporeae or Confervoid Algae, derived from the Micrographic
Dictionary, this being an accessible authority.

Algae form a class of the thallophytes or cellular plants in which the
physiological functions of the plant are delegated most completely to
the individual cell. That is to say, the marked difference of purpose
seen in the leaves, stamens, seeds, etc., of the phanerogams or
flowering plants is absent here, and the structures carrying on the
operations of nutrition and those of reproduction are so commingled,
conjoined, and in some cases identified, that a knowledge of the
microscopic anatomy is indispensable even to the roughest conception of
the natural history of these plants; besides, we find these plants
so simple that we can see through and through them while living in a
natural condition, and by means of the microscope penetrate to mysteries
of organism, either altogether inaccessible, or only to be attained by
disturbing and destructive dissection, in the so called higher forms of
vegetation. We say "so-called" advisedly, for in the Algae are included
