variety on our fea-coafts, of which the moll curious that have 
reached my knowledge, for lhape and colour, are, 
N°. xxxix. Fucoides purpureum eleganter plumofum " . 
N°. xl. Fucoides rubens varie diffeSlum °. Of both which plants 
the capillary ramifications are wonderfully diftinbt, orderly, and of a 
moft beautiful lake- colour, even to the very extremities, when this 
fucus is in feafon ; but when they are either immature, or on the 
decay, their extreme fhoots are pale ftraw-coloured.

N c ’. xlv. Fucus membranaceus purpureus latifolius pinnatus \ 
N\ xlvi. Fucus membraitaceus rubens angufiifolius marginibus 
ligulis armatis “, a plant of great beauty as to colour, but in lhape 
exceeding all I have yet feen. 
N°. xlvii. Fucus membranaceus Ceranoides ; the Scotch call it 
Dils ; the Irifh, who chew it, Dulefh ; found by the fame w . 
N e ’. xlviii. The largeft and nobleft plant of this membranaceous 
kind is the bloody fea-dock, Lapathum marinum fanguineum , or 
Alga folio membranaceo purpureo Lapathi fanguinei figura & mag- 
nitudine \ When it is fomewhat faded, the leaf is red variegated 
with ftraw-colour, not unlike that of a ftriped tulip ; when it is in 
full feafon, of a rich perfeft blood-colour, and fo fmooth and thin 
withall, that, when well difplayed on paper, feeling can hardly 
diftinguilh it from the natural furface of the paper ; and it flicks 
fo tenacioufly, that the paper may be folded or rolled, nay even 
plaited into the mount of a fan (as has been experienced by fome 
curious ladies of this county) without any danger of the plant’s 
ftarting. Thefe membranaceous plants in general, though they 
retain their high colourings for years, (which fhews how finely their 
colours are prepared and diftributed) are indeed lo extreamly thin, 
that a gentleman of my acquaintance, with no great impropriety, 
called N°. xlii. (viz. Fuc. membran. pur pur.) the fenfitive Fucus ; 
t{ for if brought near the fire juft to warm, and not heat it too much, 
its edges warp up, and in this ftate, if a finger is moved towards 
them, they fbrink from it, and recover their lituation again when
