?ji ^ King-fun ; Chloride of Mercury ; Calomel. My 

 specimen of the substance called King-fun, consists of small, 

 brilliant, colourless, transparent crystals, mostly thin and plate- 

 like, or even pectinated; some are needle-shaped. Chemical 

 examination proves it to consist of two distinct substances, 

 namely, Chloride of Mercury and Sulphate of Liine. The 



i Dr. McCartee says that at Ningpo what is sold as L&h-fan " seems to 

 be Sulphate of Copper." Letter to D. H., 5 Dec., 1867.
