278 QUARTERLY CHRONICLE, 
of either of the organic kingdoms. They cannot be classed 
with the sponges Rhizopoda, Grengarine, or ciliated Infusoria, 
or with the Alge and Fungi. There is nothing even by 
which we can find a connection between the Labyrinthule and 
the Algw, or other allied Flagellata; for the framework of 
Labyrinthula, as its development shows, is to be considered 
as an exudation of cells—as a peculiar fibrous, jelly-like 
formation. Supported by this we are led to the Palmellace, 
Conjugate, and F lagellatee, where we can see such forma- 
tions, but where the giving out of the jelly-like substance is 
confined to certain portions of the surface of the cells, whereby 
single or star-like points are formed, to which the separated 
cells remain sticking. We find numerous examples of this 
in the Anthophysa, Doxococus, Colacium, and the like. 
These complex organisms, the production of the separation of 
many cells, could be compared with the network of Labyrin- 
thule, although the cells in this case remain fixed, and never 
move on the framework. 
It would be possible to compare the Labyrinthule to some 
kinds of compound diatoms which are covered with a gela- 
tinous substance: for example, Bacillaria paradoxa; but then 
the cells of the diatom, and the fusiform bodies of the 
Labyrinthula differ so widely in structure and development, 
that no comparison is admissible. 
3. “ On Clathrulina, @ new Actinophrys genus.” by Prof. 
L. Cienkowski—This is a very beautiful stalked form. Its 
development and structure are described and illustrated in a 
neatly drawn plate. 
4." On the Origin and Development of Bacterium termo 
Duj,” by Joh. Liiders, of Kiel. 
5. Remarks on the preceding Paper,” by Professor Dr. 
Hensen, of Kiel. 
The first of these communications is, it appears, by a lady. 
She has before this, in Von Mohl’s ‘ Botanische Zeitung,’ 
1866, p. 33, endeavoured to show that certain Fungi and the 
Vibriones have a most intimate relationship. This opinion 
has been strongly opposed by Professor Hallier in a paper 
published in the ‘ Archiv’ (1866), p. 67, which we noticed in 
this Chronicle. 
Frau Liiders in this paper endeavours to show that many 
vibrio-forms may be produced by growing various moulds. 
Ske gives figures of vibrio-forms from Botrytis acinorum, 
grown in flesh-water, from Mucor mucedo grown in pure 
spring-water, from Penicillium glaucum, grown in pure water 
and other liquids. The history of the Vibriones, Bacteria 
and the yarious forms of the lower fungi, varying, as they do,
