Hab. Same as Cladophytum comatum, but rarely growing in such 
dense tufts. 
The three genera of Entophyta of which I have now spoken, are all 
so constantly found in the Julus marginatus, that I look upon it as 
a natural condition, and should I hereafter meet with an individual 
without them, I will consider it a rare exception, because, in one 
hundred and sixteen individuals which I have examined during the 
past thirteen months, in all seasons, and af all ages and sizes of froth 
one up to three inches of the animal, | have invariably found them. 
It cannot be supposed that these are developed and grow after death, 
because I found them always immediately upon killing the animal. 
Whilst the legs of fragments of the animals were yet moving upon 
my table, or one-half of the body even walking, I have frequently 
been examining the plants growing upon part of the intestinal canal 
of the same individual. And upon the entozoa, these entophyta will 
be frequently found growing, whilst the former are actively moving 
about. I found among others an Ascaris three lines long, which had 
no less than twenty-three individuals of Enterobrus, averaging a line 
in length, besides a quantity of the other two genera growing upon 
it, and yet it moved about in so lively a manner that it did not ap- 
pear the least incommoded by its load of vegetation. This specimen 
I have preserved in a glass cell in Goadby’ s solution, and exhibit it 
to the Academy. 
The animals were uniformly enjoying good health, 7. e. all the or- 
ganic and animal functions were natural; they eat, grew, reached 
their definite size, reproduced, and, in fact, presented all those actions 
characteristic of the normal state of existence of the animal. 
The genus Julus is an extensive one, and its species are found in 
all the great parts of the globe, and as their habits are the same, the 
conditions for the production of the entophyta wil! be the same ; and 
I think I do not go too far when I say, they will be constantly (cand 
throughout the genus in any part of the world, so that naturalists 
and others may, upon examination, readily verify or contradict the 
statements which I have this evening presented. 
From these facts we perceive that we may have entophyta in 
luxurious growth within living animals, without affecting their health, 
which is further supported by my having detected my codermatoid 
filaments in the caecum of six young and healthy rats, examined im- 
mediately after death, although they existed in no other part of the 
body. These filaments were minute, simple and inarticulate, measur ing 
from 1-5000th to 1-1428th in. in length, by 1-16,000th ‘of an al 
in breadth. With them were also found two species of Vibrio. 
Even those moving filamentary bodies belonging to the genus 
Vibrio, 1 am inclined do think, are of the character of algous vegeta- 
tion. Their movement is no objection to this opinion, for much higher 
confervee, as the Oscillatorie, are endowed with inherent power of 
movement not very unlike that of the Vibrio, and indeed the move- 
ment of the latter appears to belong only to one stage of its existence. 
Thus, in the toad (Bufo americanus), in the stomach and small in- 
testine, there exist simple, delicate, filamentary bodies, which are of
