Many of the fame colours are dyed upon different fluff's with different materials ; as red-wood ufed in cloth, not in filks ; annotto in filks, not in cloth ; fo that they may be dyed at feveral prices. — 13'. Scowring, and wafhing of fluffs to be dyed, is to be done with appropriate materials ; as fometimes with ox-galls, fometimes with fullers earth, fometimes with foap : this latter being pernicious in fome cafes, where pot- afhes will flam or alter the colour. — 14 . Where great quan- tities of fluff's are to be dyed together, or where they are to be done with great fpeed, and where the pieces are very long, broad, thick, (3c. they are to be differently handled, both in refpect to the veficls and ingredients, — 15 . In fome colours and fluffs the tingent liquor muft be boiling ; in other cafes blood-warm, in fome it may be cold. — 16 . Some tingent li- quors are fitted for ufe by long keeping ; and in fome the virtue wears away by the fame. — 17°. Some colours, or fluffs, are beft dyed by reiterated dippings ever into the fame liquor at feveral intervals of time ; and fome by continuing longer, and others leiTer whiles therein. — 18". In fome cafes, the fnatter of the vefl'el wherein the liquors are heated, and the tinctures prepared, muft be • regarded ; as that the kettles be pewter for bowe-dye.— 19°. Little regard is had how much liquor is ufed in proportion to the dying drugs ; the liquor . being rather adjufted to the bulk of the fluff, as the vefiels are to the breadth of the fame ; the quantity of dying drugs being proportioned to the colour higher or lower, and to the fluffs both ; as likewife the falts are to the dying drugs. Concerning the weight which colours give to filks, for in them it is moft taken notice of, as being fold by weighty and being a commodity of great price ; it is obferved, that one pound of raw filk lofes four ounces by waffling out the gums, and natural fordes. — That the fame fcoured filk may be raifed to above thirty ounces from the remaining twelve, if it be dyed black, with certain materials. — That the rea'fon

■ why black colour may be dyed the heavieft is, that all pon- derous drugs may be dyed black, being all of colours lighter than it ; whereas, perhaps, there feem to be few or no ma- terials wherewith to encreafe the weight of filk, which will confift with fair light colours ; fuch as will having been ufed, as white arfenic to carnations. Of things ufeful in dying, efpecially black, nothing encreafes

1 weight fo much as galls ; by means whereof black filks re- cover the weight which they loft by wafhing out their gum :

! Nor is it counted extraordinary, that blacks (hould gain a- bout four or fix ounces in the dying upon each pound. — Next to galls, old fuftic encreafes the weight, about ft-g in 12.— Madder about one ounce.. — Weld half an ounce. — The blue fat, in deep blues of the fifth flail, adds no confiderable weight. — Neither do logwood, cochineel, or annotto: nor feven copperas of itfelf, where galls are not. — Slipp adds much to the weight, and gives a deeper black than coppe- ras, which affords a good excufe for the dyers that ufe it. —
