Hence there is some reason to induce us to think, that the lacteals frequently 

 convey liquors, which are not white ; and that chyle may not improperly be di- 

 vided into 3 sorts at least, viz. white, pellucid, and intermediate to these; con- 

 trary to the opinion of those anatomists, who thought it to be always white, as 

 that word is contradistinguished from pellucid; although by chyle they under- 

 stood, as I likewise do, the effects of drink, as well as meat, concocted.

An Account of a sort of Paper made of Linum Asbestinum found in Wales, 

 in a Letter to the Editor, from Edward Lloyd of Jesus Coll. Oxon. N° 1 66, 

 p. 823. 



The lapis amianthus or linum fossile asbestinum, abounds in the parish of 

 Llan-Fair yng Hornwy, in the northern parts of Anglesey, where it runs in 

 veins through a rock of stone, in hardness and colour not unlike flint. These 

 veins are generally about \ of an inch deep; which is almost the extreme length 

 of the amianthus. It is composed of a lanuginous matter exactly resembling 

 that of pappous or downy plants; but so compact, that till you draw a pin, or 

 some such sharp thing, across its grain, it appears only a shining stone; for not 

 the least filament of lint is to be perceived in it. In its natural form some of 

 it looks whitish, and some straw-coloured, but all shining : but when pounded 

 in a mortar, the brightness disappears, and the whole becomes whitish. Above 

 and beneath the veins there is a very thin septum of terrene matter, between 

 the amianthus and the stone, to which it adheres. On putting a small quantity 

 of the lint in the fire, it became red hot; but though it remained there ^ of an 

 hour, I could not perceive that it was at all consumed. Some of it being 

 twisted in form of a wick, and dipped in oil, it gave as good a flame as other
