ous shades of red on
wool with this class of dyes.

_Scarlet_.--The dye-bath is made with 3 lb. Titan Scarlet C B, and
10 lb. acetate of ammonia. This gives a good bright shade of scarlet,
which is fast to acids and soaping, although not fast to light.

_Scarlet_.--Dye in a bath made with 3 lb. Diamine Scarlet B and 10 lb.
Glauber's salt. This yields a light shade, not so fast to acids as the
last, but equally fast to soaping and light.

_Scarlet_.--Make the dye-bath with 3 lb. Benzopurpurine 4 B, and
10 lb. Glauber's salt. This also gives a good shade of Scarlet fast to
soaping. It is turned dark blue by acids, and is not fast to (p. 102)
light. It is very largely used on underwear goods, but is not so
satisfactory for this as the Titan Scarlet C B, or Benzo Fast
Scarlet B S.

_Scarlet_.--The dye-bath may be made with 3 lb. Brilliant Congo G,
10 lb. Glauber's salt and 2 lb. acetate of ammonia. This gives a
satisfactory shade of scarlet.

_Bright Scarlet_.--The dye-bath prepared with 2 lb. Geranine G, 5 lb.
sulphate of soda, 5 lb. acetate of ammonia. Work at the boil for one
hour, then wash and dry.

_Dark Crimson_.--Prepare a dye-bath with 1-1/2 lb. Chrysophenine,
1-1/2 lb. Hessian Violet, 25 lb. salt. Heat to 150 deg. F., enter the
goods, heat to boil and dye boiling for one hour, take out, rinse and
wash.

_Scarlet_.--A brilliant shade of scarlet can be dyed in a bath of
3 lb. Benzo Fast Red, 1 lb. Chrysophenine, 10 lb. Glauber's salt and
2 lb. acetic acid.

_Fast Red_.--Dye the wool in a bath boiling, containing 1 lb. Diamine
Fast Red F, 10 lb. Glauber's salt, and 2 lb. acetic acid, until the
bath is exhausted, then add 3 lb. fluoride of Chrome and work half an
hour longer at the boil.

_Bordeaux_.--Dye with 3 lb. Diamine Bordeaux, and 10 lb. Glauber's
salt.

_Pink_.--Dye with 2 lb. Diamine Rose B D, 10 lb. Glauber's salt and
1 lb. acetic acid.

The basic red dyes are not very numerous, and comprise Magenta,
Saffranine, Acridine Reds, Acridine Scarlets, Rhoduline Reds,
Rhodamine and Neutral Beds. For successful dyeing they require a
perfectly neutral bath. This bath should contain 10 per cent. of
Glauber's salt, and is started cold and not too strong; when all the
material has been entered the steam may be turned on and the
temperature slowly raised, the material being turned over and over.
The operation is continued only until the bath has been exhausted of
colour, when it is stopped, and the
