tendency to becoming repeatedly encysted or coated with a thick 

 hyaline many-layered covering, the long and densely arborescent 

 body-mass becoming now and again protruded through an 

 irregular, seemingly torn-like, aperture ; 3rd, that immersed in the 

 body-mass occur often numerous irregularly figured deep crimson- 

 coloured pigment-granules — giving to these organisms when viewed 

 under moderate powers a decidedly red colour. Cienkowski's forms, 

 too, did not show incepted, food. — these did, of varied kinds,and con- 

 siderable quantity. Nothing could be more beautiful or striking 

 in the way of beings of this type than the noble specimen now 

 under view ; streaming out from the opening in the coat or cyst 

 emanated a large trunk-like projection of the body-mass densely 

 charged with orbicular bluish-coloured granules, and the accom- 

 panying variously figured reddish ones, this trunk-like portion 

 becoming by degrees ramified in a highly compound and extensive 

 manner into numerous and wide-spreading branches ; these branches 

 giving off" the linear and numerous filamentary tracks, the whole 

 reticulated in the most intricate and varied manner, and the ulti- 

 mate tracks showing the spindles (the orbicular bluish bodies 

 adverted to, now spindle-shaped, seemingly, by pressure) slowly 

 executing their strange progression up and down the tracks, often 

 in long files or rows, at other times crowded or isolated. Another 

 diff"erence — one of habit merely — (in addition to the bluish, not 

 orange or colourless, spindles) is, that whereas one of Cienkowski's 

 species would take many hours (as many as 24) to spread out and 

 show their arborescent appearance on a slide, as many minutes 

 would suffice for such a grand oak-tree as that now under view to 

 grow up, as it were, before one's eyes. As to the supposed mode of 

 progression of these spindles, and other points in connection with 

 this remarkable form and with those of Cienkowski, as regards that 

 author's conclusions, Mr. Archer ventured upon some observations 

 at the meeting. To discuss these would take too long in brief 

 minutes like the present, and must be deferred to a more fitting 

 opportunity ; but even should this curious organism be found on 

 the Continent ere that opportunity could be had by Mr. Archer, 

 still it would be something to have secured in our pages a record 

 of priority of its detection. He would not venture here, then, 

 to give any further dcscriptio7i for the present, but should any- 

 thing further of interest connected with it reveal itself, he would 

 take an opportunity to bring it once more before the Club. It 

 must be at least regarded as interesting to meet with, in the fresh 

 water, a form at least so close to the marine organisms forming, 

 according to the views of so acute and distinguished an observer 

 as Cienkowski, a new type of sarcodic beings. It is true that some 

 might hold that the non-nucleated spindles would keep the present 

 organism out of the Labyvinthulea, but even were it so, nothing 

 could more closely or more surprisingly simulate his forms than 

 that now exhibited. Let not those who may peruse this crude note 

 think we have here to do simply with a Gromia ; if not a Labyrin-
