_Dark Maroon._--Dye with 6 lb. Primuline, 3 lb. Titan ingrain blue and 20 lb. salt, then diazotise and develop with beta-naphthol. _Dark Crimson._--Dye with 5-3/4 lb. Primuline, 1/4 lb. Titan ingrain blue and 20 lb. salt, then diazotise and develop with beta-naphthol. _Dark Blue._--Dye with 3 lb. Zambesi blue B X, 2 lb. soda and 20 lb. Glauber's salt, then diazotise and develop with amidonaphthol ether. _Dark Brown._--Dye with 8 lb. Zambesi brown 2 G, 2 lb. soda and 20 lb. Glauber's salt, then diazotise and develop with toluylene diamine. _Blue Black._--Dye with 4 lb. Zambesi blue B X, 2 lb. Zambesi black D, 2 lb. soda and 20 lb. salt, then diazotise and develop with 3/4 lb. toluylene diamine and 1/2 lb. beta-naphthol. _Red._--Dye with 4-1/2 lb. Primuline, 1/2 lb. Diamine fast yellow A and 20 lb. salt, then diazotise and develop with beta-naphthol. _Dark Brown._--Dye with 4 lb. Primuline, 1 lb. Diamine azo blue R R, and 20 lb. salt, then diazotise and develop with beta-napthol. _Deep Chestnut Brown._--Dye with 5 lb. Diamine cutch, 1 lb. soda and 20 lb. Glauber's salt, then diazotise and develop by passing for twenty minutes in a boiling bath of soda. _Dark Brown._--Dye with 4 lb. Diamine cutch, 1 lb. Diamine black B H, 2 lb. soda and 20 lb. Glauber's salt, then diazotise and develop with phenol. _Black Brown._--Dye with 1 lb. Diamine brown M, 1-1/2 lb. Primuline, 1 oz. Diamine black B H, 2 lb. soda and 20 lb. Glauber's salt, then diazotise and develop with phenylene diamine. _Blue._--Dye with 2 lb. Diaminogene blue B B, 1/2 lb. soda and 20 lb. Glauber's salt, then diazotise and develop with beta-naphthol. A dark blue is got by using 8 lb. of Diaminogene blue B B in the same way. _Dark Blue._--Prepare the dye-bath with 1-1/2 lb. Diaminogene blue B B, 1-1/10 lb. Diamine azo blue R R, 2 lb. soda and 20 lb. Glauber's salt. Dye at the boil for one hour, rinse slightly in cold water, then enter into a fresh cold bath prepared with 4 lb nitrite of soda previously dissolved in water, and 12-1/2 lb. hydrochloric acid. For subsequent lots in the same bath one-third of these additions is sufficient. After diazotising rinse the goods in a bath weakly acidulated with hydrochloric or sulphuric acid, and then immediately develop with beta-naphthol.
