into the latter. Thus, for dying cotton black, the mordant 

 commonly used is a boiled decoction of fustic, which of 

 itself gives a yellow color ; but, after having received this, 

 will receive a permanent black dye, The bark of the quer- 

 citron will answer instead of fustic. 



A good black for woolens is only to be obtained by first 

 dying them a deep blue, fixing that color with its proper 

 mordant; and then they are to be put in the black dye ? 

 with its mordant. 



The different hues of gray are merely mixtures of white 

 wool with suitable proportions of wool dyed black, in th 

 manner just mentioned. 



Green is a mixture of blue and yellow dyes ; and may be 

 a lighter green, by more of the yellow first given it, with 

 its mordant, and afterwards less of the blue, with its mor- 

 dant; or, vice versa, for a deeper green. 



The same may be observed of other hues, which are 

 produced by a mixture of two, or more, of the primitive 

 colors. The deepness, or the lightness, of any particular 

 primitive color, or of mixtures of either, is obtained by a 

 proper apportionment of the dying ingredients, with their 

 proper mordants 5 that is, where the color is intended to be 

 deep, more of the ingredients are to be used ; and less, 

 where it is to be light. 



After premising thus much, we will give a list of differ- 

 ent colors produced by different vegetable substances, with 

 the mordant proper for each, as far as we have been ena- 

 bled to obtain a knowledge of the same i
