The Vernacular names for LAC are Laksha, Sans. Lakh, Hind. Guz. 

 Komburruki, Tarn. Commoleka, Tel. Lakada, Cey. Khejijk, Burmah. 

 Balo, Java. Ambalau, Malaya. In a note on Roxburgh's paper, " On the 

 Lacsha, or Lac insect" (Asiatic Researches, Vol. ii. Lond. 1799), Sir. W. 

 Jones observes, " The Hindus have six names for LAC ; but they gene- 

 rally call it Lacsha, from the multitude of small insects, who, as they 

 believe, discharge it from their stomachs, and at length destroy the tree 

 on which they form their colonies. A fine Pippala, near Crishnayar, is 

 now almost wholly destroyed by them." 



Dr. Carter's papers on the Coccus Lacca are contained in Vol. vii. 

 Nos. 37 and 41 of " The Annals and Magazine of Natural History." 



In commerce LAC, gathered with the twigs on which it is formed, is 

 called STICK-LAC ; the resin removed, and its colouring matter washed 

 out, is SEED-LAC ; this melted in masses is LUMP-LAC ; or melted, strained, 

 and run into thin layers, SHELL-LAC. LACQUER is a varnish of LAC. The 

 Lac-work of Hydrabad, in the Deccan, is celebrated. See " Dyes." 

 Crawfurd states that there is a dye on Sumatra called Laka, the wood of 

 the tree named Tanarius major by Rumphius (Amb. lib. v. ch. 38, tab. 

 122), but I am unable to identify it with any species recognised by 

 botanists : Blume (Rumphia) gives two species of Myristica with the 

 vernacular name of Lakha.
