LACCIC ACID crystallizes, has a wine-yellow color, a sour taste, is soluble in ’alcohol, and ether. It was extracted from sticklac by Dr. John. „
LACCINE is the portion of shellac which is insoluble in boiling alcohol. It i s ^Junstbrittle, translucid, consisting of agglomerated pellicles, more like a resin than any 1 5
else. It is insoluble in ether and oils. It has not been applied to any use. ve
LACE MANUFACTURE. The pillow-made, or bone-lace, which formerly = ,
occupation to multitudes of women in their own houses, has, in the progress 01 g rS tchanical invention, been nearly superseded by the bobbin-net lace, manufactured at 1 ^by hand-machines, as stockings are knit upon frames, but recently by the po' ve j . tl , ewater or steam. This elegant texture possesses all the strength and regularity 0old Buckingham lace, and is far superior in these respects to the point-net and watPwhich had preceded, and in some measure paved the way for it. Bobbin-net ®said to surpass every other branch of human industry in the complex ingenuity^. QUSmachinery; one of Fisher’s spotting frames being as much beyond the most cchronometer, in multiplicity of mechanical device, as that is beyond a common roa-jack. (,ular
