recrementitious

"It is to be remarked that natural perception belongs to other parts of the body besides fibres; to wit, to the parenchymata, bones, marrow, fat, blood, recrementitious juices, humours of the eye, and such like, all which are irritable, and increase the irritable constitution of the parts, but these parts hardly admit of the existence of animal perception."

And, if there be, whether they be barely fuliginous and recrementitious exhalations, or, at least in part, Metallin Flowers?
