wall, so evenly sometimes that a reticulated effect is presented by 
the interspaces. But the puzzling and remarkable point was that, 
immersed in the centre of nearly every one of these so hermetically- 
closed cells, there presented itself some kind of foreign body, gene- 
rally resembling a young and small Pandorina, or some such mul- 
berry-shaped cluster of cells, but other things were present in some 
— sometimes a minute diatom, sometimes one or two joints of Didy- 
moprium Borreri, sometimes what appeared to represent a fragment 
of some nostochaceous filament. These in densely filled cells are, 
of course, sometimes hard to be made out, requiring strong light 
and careful focussing. If any of these bodies were more than 
usually long, or exceeded materially the ordinary diameter of the 
containing cell, this latter became more or less elongate aud dis- 
torted, and in such usually the foreign body was more readily per- 
ceived. It becomes a query what this organism can be? The 
green colouring granules are, to all appearance, chlorophyll. It is, 
perhaps, somewhat like a quiescent or rigid and thicker walled 
state of Monas grandis (Ehr.), but it is more probable to be some 
quiescent state of some rhizopodous creature, notwithstanding its 
green and very protococcoid appearance. None of the cells ever 
showed any appearance of self-division. Sometimes similar looking 
cells are mingled with these, probably a further stage, in which an 
inner wall appears to be formed, which latter is much thickened, 
and presents an undulate outline, the extremities or apices of the 
prominences being in contact with the much thinner spherical outer 
wall, the contents acquiring a lightish brown or somewhat orange 
colour, enclosing a large conspicuous, excentric, red (nuclear ?) 
granule. Though Mr. Archer strongly suspected that this was an 
advanced state of the former, he could not yet be certain. He had 
several times lately met with this production in our moor pools in 
various parts, no doubt one and the same thing, but the present 
examples were probably the most striking he had encountered as 
regards the foreign bodies enclosed within the thin-walled cells ; 
and he ventured to think, enigmatical as it was, but yet by no means 
attractive as a “popular” display, that this production deserved 
the Club’s attention.
