Palladium-salt . — A dilute solution of the dichloride is not precipitated by chloride of 
palladium. On concentrating the mixture and allowing it to cool slowly, reddish-yellow 
prisms make their appearance : by rapid evaporation a brick-red crystalline powder is 
obtained. Alcohol added to the aqueous solution of the two salts throws down the 
double salt as a chocolate-coloured crystalline magma composed of small interlaced 
needles. I have not analysed this compound. 
Gold-salt . — Beautiful golden-yellow needles, difficultly soluble in cold, easily soluble 
in boiling water, and containing

as shown by the following analyses : — 
I. 0-6200 grm. of gold-salt gave 0-4159 grm. of carbonic acid and 0-2032 grm. of 
water. 
II. 0-3540 grm. of gold-salt gave 0-1490 grm. of gold.

Mercury-salt . — Delicate crystalline needles or laminae, sparingly soluble in water and in 
alcohol, obtained by mixing the chloride of the diphosphonium with mercuric chloride.
