tered, and again boiled 1 hour ; the colour thus obtained was 

 a bright full red brown. In the same manner a similar shade 

 of red brown, or others yellower, may be dyed in the same 

 dyeing liquor, adding the alum after the red part of the colour 

 has become fixed. After the above a yellow brown approach- 

 ing to a snufF colour was dyed ; — for lOOlbs. of worsted goods 

 added 2lbs. of camwood, lOlbs. of mull madder, 9lbs. of rasped 

 fustic, 3lbs. of red argol, 14 measured ounces of sulphate of 

 indigo, and 2lbs. of sulphuric acid, — boiled 1 hour. Took up, 

 added ^Ibs. of alum, lib. of sulphate of coppei-, 2lbs of rasped 

 fustic, and 4 measured ounces of sulphate of indigo ; entered 

 and boiled 1 hour. A small portion of sulphate of copper in- 

 creases the brilliancy and adds much to the intensity of the 

 yellow browns. 



The mode of dyeing olive and brown now described, has 

 only been introduced to the dyeing establishments of this coun- 

 try since the last 20 years : it is called by dyers the sour way. 

 The same colours, possessing however little bx'illiancy, were 

 dyed with camwood, fustic, and logwood ; the mordant em- 

 ployed was sulphate of iron. 



For 59lbs. of a coarse woollen cloth called Calmuck, a full 

 olive brown. Dyed in an iron pan containing 400 gallons of 

 water; added 20lbs. of rasped fustic, 8lbs. of rasped camwood, 

 Gibs, of chippetl logwood ; boiled 1 ^ hour : took up, emptied 

 the dyeing vessel half-way, filled with fresh water, and added 

 2lbs. of sulphate of iron, entered the cloths turning quickly 

 10 minutes, raised gradually to ebullition, and boiled 10 mi- 

 nutes. 



In the same manner may be dyed all the shades of copper, 

 brown, and olive.
