olives, readily mix with this fluid even when cold. Eupion, when cold, 

 readily dissolves chlorine, and bromine still more so ; but heat sepa- 

 rates these bodies without altering it. Iodine dissolves in it even in 

 the cold with its violet colour, and much more readily when hot, and 

 on cooling it crystallizes in part. Phosphorus, selenium, and sul- 

 phur dissolve readily in eupion when heated, but not when cold ; on 

 cooling, the two former precipitate totally, and the latter partially. 

 Naphthaline, camphor, stearine, cetine, cholesterine, paraffin, and bal- 

 sam of copaiba dissolve in it in the cold, and much more so when 

 hot. Tallow dissolves in it at 80"^ Fahr., but at 68° the solution be- 

 comes clotted, probably the stearine separates, and the elaine remains 

 in solution. Bees' wax dissolves in eupion when heated, but the 

 greater part separates on cooling. Colophony is partially soluble in 

 the cold, but perfectly at a boiling heat. Benzoin, gum anime, copal, 

 and gum lac, dissolve only partially at a boiling heat, and they preci- 

 pitate either totally or partially on cooling. Caoutciiouc swells in 

 eupion in an extraordinary manner, yet does not dissolve in it in 

 the heat of a stove, but readily at a boiling temperature. The solu- 

 tion does not lirv by exposure to the air. Heated upon a plate of glass 

 in a stove, it soon becomes adhesive, may be drawn into threads, and 

 eventually dries. The caoutchouc remains as a brittle varnish, which 

 muv be scraped off in small scales like dried gum or varnish. 



The following substances have no action upon eupion : Concen- 

 trated nitric acid, concentrated sulphuric acid, muriatic, acetic, oxalic, 

 tartaric, succinic, and citric acids ; potassium, hydrate of potash, 

 hydrate of lime, solutions of potash, lime, barytes, strontian, and am- 

 monia; the carbonated alkalies, deutoxide of lead, peroxide of mer- 

 cury, peroxide of manganese, oxide of copper, bichromate of potash. 



Eupion is an excellent substance for keeping potassium in, proba- 

 bly also for separating stearine from elaine ; and is a most remark- 

 able substance for giving light by combustion, giving no soot even 

 when mixed with paraffin. — Ann. de Cliim. et de Fhijs. 1. p. G9.
