tirely ungummed, when it is turned, and the portions of the 

 skeins on the rods scoured. It is then placed in a second 

 bath containing three ounces of soap to the pound of silk, 

 and turned every quarter of an hour several times. The sec- 

 ond bath, with the addition of ten per cent, of soap, may be 

 used as the first bath for the next lot. The silk, by this treat- 

 ment, retains more of its gloss and smoothness, and does not 

 become woolly, as is frequently the case on boiling. To dye 

 it brown, soap it and ground it without washing in the clear 

 liquid obtained by boiling four to five ounces of turmeric, 

 and allowing it to settle. Then wash twice, place from ten 

 to twelve hours in an alum-bath, wash twice again, and dye at 

 113 with fustic, archil, brazil-wood, logwood, and some soap, 

 according to the tint desired. After dyeing, it is cleansed 

 with fuller's earth, Avell rinsed, and cleared with a little oil 

 dissolved in a solution of potash. 24 (7, 1873, 99. 



COLOEIXG KID GLOVES. 



According to Reimann's Journal of Dyeing^ the gloves are 

 to be smoothly fitted on a wooden form, and the coloring so- 

 lution is to be brushed on ; the different colors being pro- 

 duced as follows: Black: The glove is washed or brushed 

 with alcohol, dried, and then brushed with a decoction of log- 

 wood, and after ten minutes the logwood liquid again applied ; 

 after ten minutes more, dipped into a solution of green vit- 

 riol, and then brushed off with warm water. If the color is 

 not as dark as desired, some decoction of fustic or quercitron 

 may be added to the logwood liquid. Nitrate of iron may 

 also be substituted with advantage for the green vitriol. 

 When the glove begins to dry, it is rubbed with some fine 

 olive-oil and French chalk, and then placed between flannel ; 

 and then pressed, again well rubbed with olive-oil and the 

 chalk, and drawn upon the wooden form. None of the color- 

 ing solution must reach the interior during the operation. 

 Brovm: A decoction of fustic, brazil-wood, and logwood, with 

 some alum, is brushed on. The shade desired must regulate 

 the proportions of these ingredients. To darken the color, a 

 small quantity of green vitriol may be used. Morocco-red: 

 A decoction of cochineal with the addition of a little chloride 

 of tin and oxalic acid. The shade may be readily deepened 

 by the addition of a little logwood. Gray: A decoction of
