Tliis species, wliicli Mr. Greville regrets is not British, is in- 

 valuable as a glue and varnish to the Chinese. Tliough a small 

 plant, the quantity annually imported at Canton, from the prov- 

 inces of Fokion and Tche-kiang, is stated by Mr. Turner to be 

 about 27,000 lbs. It is sold at Canton for 6d. or 8d. j)er pound, 

 and is used for the purposes to which we apply glue and gum 

 arable. The Chinese employ it chiefly in the ' manufacture of 

 lanterns, to strengthen or varnish paper, and sometimes to thicken 

 or give a gloss to silks or gauze. In addition to the above account 

 from Mr. Turner, Mr. Neil remarks that it seems probable that 

 this is the principal ingredient in the celebrated gummy matter 

 called cinchon, or haitsai, in China and Japan. Windows, made 

 merely of slips of bamboo crossed diagonally, have frequently 

 their lozenge-shaped interstices wholly filled with the transparent 

 gluten of the Haitsai. Grev., Alg. Brit. xix. ; Lind., Nat. Syst.

 strongest cement.

It has been extensively collected on the coast of Ireland, 

 washed, bleached, and employed for making blanc-mange, and 

 for other purposes, in lieu of isinglass. It was at one time sold by 

 peasants at $25 per pound, though now so common as to be re- 

 duced in price. Ci'ypt. Eng. It is converted into size for the use
