tube, causing it to resemble the windpipe. ‘In the month 
of December,” Sir J. G. Dalyell states, “a group was reco- 
vered from the sea, resembling a copious handfull of white, 
crisp, baked horse-hair, which rose two inches high, and 
occupied a vessel of four inches diameter. Closer inspec- 
tion discovered this to be a vast congeries ;—one of not 
fewer than 500 snowy tubes, crowned by scarlet animated 
blossoms of various hues. In the aggregate it may be 
compared to a beautiful tuft of pinks decorating a flower- 
garden.” It is not often obtained in the west of Scotland. 
It seems more common in the north of Ireland. Mr. R. 
Paterson, of Belfast, says, “Having dredged a specimen, 
and having placed a detached tube of it in a jar of sea-water, 
this severed one, by its change of place, caught myeye. It 
was not merely that it was sinking in the jar, but that it 
was coiling itself up, uncoiling, stretching, twisting, knotting 
itself in a way that resembled the Gordius aquaticus ;” thus 
showing that the stem is not only flexible, but, under cer- 
tain circumstances, is truly and entirely under the control 
of the zoophyte.
