By the fame Principles of producing any vifible 
Objed with a fmall Number of Colours, he arrived 
at the Skill of producing in the Loom all that the Art 
of Painting requires. An Art likewife often attempt- 
ed, but as often abandoned, and declared impoffible 
till now, as well as the other of Printing in Colours. 
And ’cis probable, many Improvements may from, 
hence be made in feveral Trades, efpecially in comb- 
ing of Wool, where the Mixing of feveral Colours 
may be of great Ufe } but he hath not yet had Time 
to apply it to any thing elfe befides Painting, Print- 
ing, and Weaving. 
The Colours ufed in Weaving being only fuper- 
ficial, and fo differing from both the impalpable and 
the .material Colours, and not being to be fo clofely 
joined or incorporated together as thofe, will not of 
themfelves produce a White or Blacky but only a 
Light Cinnamon /Wherefore, in Weavinghe hath been 
obliged to make ufe of 'white and Threads, befides 
red, yellow, and blue y and tho’ he found he was able 
to imitate any Pidure with thefe five Colours, yet for 
Cheapnefs and Expedition, and to add a Brightnefs 
where it was required, he found it more convenient to 
make ufe of feveral intermediate Degrees of Colours. 
There are two Ways in Ufe at Brujfels , and at the 
Goblins in Paris , for making Lapeftry after the 
common Manner : One they call the fiat Way , and 
the other the upright » In the fiat Way they have 
the Warp ftretched in a Frame length-wife of the 
Piece: It is made of white Worfted, and the Pattern 
lies dofe under it ; fo that the Workman can fee the 
Figures through the Warp: He is provided with Bob- 
bins-
