4. Nature and en of the “ cae Cells” of Radios 
ans and Colenterates.—A paper under this title was read by Mr. 
Patrick Geddes hafore the Royal Soeiety of Edinburgh | in January 
last, and an abstract of it is given in Nature of January 26, from 
which we take the ee notes. The “ Yellow Cells” referred 
to, first so named by Huxley, occur abundantly in most Radiola- 
rians. mets have a well-defined nucleus and multiply rapidly by 
ision. Heeckel made them pr obabls secreting erik or digestive 
Anemones. The author in 1878 Panes aid precee ed the g

and found it to be one-half oxygen, and fur rthe er detected starch in 
the green cells. At Naples, in October, 1881, he confirmed t 
conclusions of Cienkowski as to the pe cells of Radicedae 
and found starch invariably present. e same results were ob- 
tained with Velella, sea-anemones and jelly-fishes. On ag 
to oo a Velella gave out bubbles of gas which proved to 
be about one quarter oxygen, and similarly rae cereus gave 
gas mies was 32 to 38 per cent oxygen; and among other sea- 
anemones those specimens in which tee ‘yellow ‘ella existed gave 
a like result. A white Gorgonia contained the yellow cells and
