the atmosphere by means of the gentlest zephyr, or even the eva- 
poration continually taking place from the earth’s surface ; and from 
the numerous facts already presented of the presence of cryptogamic 
vegetation in many cutaneous diseases and upon other diseased sur- 
faces, I was led to reflect upon the possibility of plants of this de- 
scription existmg in healthy animals, as a natural condition ; or, at 
least, apparently so, as in the case of entozoa. Upon considering 
that the conditions essential to vegetable growth were the same as 
those indispensable to animal life, I felt convineed that entophyta 
- would be found in healthy living animals, as well, and probably as fre- 
quently, as entozoa. The constant presence of mycodermatoid fila- 
ments growing upon the human teeth, the teeth of the ox, sheep, 
pig, &e., favoured this idea, and accordingly I mstituted a course of 
investigations, which led to the discovery of several well-characterized 
forms of vegetable growth, of which, at present, I will give but a short 
description, for the purpose of establishing priority, and propose 
giving a more detailed account of them, with figures, on some future 
occasion. 
Enterobrus, a new genus of Confervacee. Simple, attached, iso- 
lated filaments consisting of a long cylindrical cell, (containing pro- 
toplasma, granules, and large translucent globules enveloped in a 
primordial utricle,) with a distinct coriaceous peduncle or stipe of 
attachment, and at length producing at the free extremity one or two, 
rarely three, shorter cylindrical cells (filled with the same matter as 
the parent cell). 
Enterobrus elegans. Filaments olive-browa, brownish yellowish, 
or colourless, at first forming a single spiral turn, and then passing in 
a straight or gently curved line to the free extremity. Pedunele, or 
stipe of attachment, adhering very firmly, coriaceous, uniformly 
brownish, narrower than the frond-cell, papillary, columnar, elon- 
gated conical or pyramidal, expanded at base and at point of attach- 
ment to frond-cell, marked with longitudinal lines, and frequently 
with transverse annular constrictions, with no definite interior strue- 
ture. Length from 1-3750th to 1-400th of an inch ; breadth 1-3200th 
to 1-1666th. Frond-cell much elongated, frequently reaching the 
length of 2 or 3 lines, uniformly cylindrical, excepting at free extre- 
mity, where it is usually clavate; breadth in full-grown individuals 
pretty uniformly 1-935th of an ich. Contents consisting of a 
colourless protoplasma, with more or less numerous, fine, translucent, 
yellowish or colourless granules, measuring about 1-15,000th of an 
inch, and numerous large, colourless, transparent globules or vesicles 
filled with fluid, averaging the 1-2870th of an inch in diameter. End- 
cells only existing in full-grown individuals, one, usually two, rarely 
three in number ; the first one cylindrical, 1-86th of an inch in length 
by 1-1000th m breadth, filled with more granules and less globules 
than the parent cell ; end-cell clavate, 1-135th of an inch long by 
1-750th broad, at the clavate end 1-638th, filled with granular matter 
and a few globules. 
Length of full-grown individual 2 to 3, sometimes 4 lines.
