\An account of a fort of V^^^r made of Linum Asheftiniim. 
foundin Wales in a Letter to the Publiflier, from Edv/ard 
LLoyd of Jefus Coll. Oxon. 
IN obedience to your commands I have here lent you 
all the account I am able to give at prefent of the 
Lapis Amianthus or Linum foffile Asbeftinum which you 
were informed (and that truly ) was to be found in the IJle 
ot Anglefey. wherein I fliall choo(e to refer it to your 
own judgment to determine whether this be the fame 
kind with the Asbejlos of the Ancients^ or in lome re- 
fpeds different from it. Nor fhall I mention any thing 
out of ^//^/^^^rj- relating to it ; well knowing that would 
prove but needlefs to you, as being not unacquainted 
with whatever has been faid ofit: But (liall oneiy give 
you lome bareinfermationsof it from my own Experi- 
ence. It is found in no fmall quantity in the Parifli of 
LLan-Fair yng Hornippy in the Northern part of Anglefey i 
where it runs ia veins through a Rock of Stone in hard- 
nefs and colour not unlike Fli^it. Thefe veins are gene- 
rally about I of an inch deep ; which is the length of the 
Amiantus^ andisleldome longer , but often fhorter. It 
is compoied of a lanuginom matter exadtly refembling 
that of pappous Flants ; but fo clofely compadt, 
that till you draw a Pin, or any (uch fliarp thing, 
crofsthe grain of it, it appears onely a fliining Stone ; 
there being not the leaft filament of //Wt6 be perceived 
in it. In its natural fcrmfomeof it looks whitijb, and 
fome Straw-colour d, but all fliining ; but if pounded in a 
Mortar, the brightnefs difappears , and the whole be- * 
comes whitijh. Note that above and beneath the veins 
there's a very thin feptum of terrene matter between the 
Amiantus , and the Stone whereto it adheres, I put a 
Imall quantity of the lint in the fre, which grew red 
hotj but though it remain cl there I of an hour, I could 
not perceive that it was any thing confumed. I twifted 
fome of it alio in form of a ^F^^/^, as you had done that
