Ill regard to the present object, being an Oscillatoria,
Captain C a u m ic h a e i , has observed to me, that he could not
perceive it either radiate or oscillate; yet he is of opinion that
it belongs to the Oscillatorice verm of A g a r d h ’s Systema
Algarum. While I am unable to disprove this, I cannot unhesitatingly
agree to it, greatly as I rely dii Captain C a r m i c
h a e l ’s opinions. The jointed filament, I conceive, might
serve as the intestinal canal, while the two wings might form
the body, of a minute animal,—a supposition which the transverse
rug* of the wings rather contribute to confirm ; but farther
I cannot go, arid have willingly given it a place in this
work, in the hope that more attention may he ultimately conferred
upon this interesting subject.
