The mealy tartareous lichenoides (18) with browri 
dilhes, forms an article of trade with the people of 
Weft Gothland. They manufacture a beautiful red 
dye from it, which they fell under the name oi hyt- 
telet (19). Dr. Hill fays we have this mofs abun- 
dantly in Leicefterfhire and Warwickftiire. 
The Welch make a red dye, with urine, from an- 
other mofs of this order, which Dillenius defcribes 
(20) by the name of The large leprous lichenoides 
with yellow plates. Thefe are not the only fpecies, 
which are endowed with a tinging quality : other 
kinds have been obferved to give a red or purple 
colour to paper in which they have occafionally been 
inclofed. Doubtlefs feveral would, upon fufficient trials, 
be found to anfwer equally well with the orchel. 
With regard to thefe cruftaceous modes in gene- 
ral, it is highly worthy our regard, that in the ceco- 
nomy of nature they anfwer lingular and important 
ufes. To an unobferving eye, no clafs of vegetables 
may appear more inlignificant, or lefs adapted to ad- 
vantageous purpofes in the creation, than thefe. This 
vulgar eftimation of things is frequently erroneous ; 
and it is certainly fo in the inftance before us. Thefe 
minute and feemingly infignificant modes ferve, un- 
der fome circumftances, to valuable purpoles. No 
fooner is a rock left bare by the fea, but thefe lichens 
lay the foundation for its future fertility. Their feeds,
