If, on theother hand, a mixture of the composition is cooled,at 157° the pink mixed crystals suddenly change into a redchemical compound having the same composition, representedby D on the diagram. This is exactly comparable with thesolidification of a compound from a liquid solution, and, as in thecompounds of ferric chloride and water of Fig. 17, or those ofgold and aluminium of Fig. 20, the curve sinks on each side ofthis point, and forms eutectic mixtures of ;2AgI with HgLat 118° and with Agl at 185\ Below these temperatures thenall solid mixtures are transformed into conglomerates of doublesalt either with Hgl,^ or with Agl.
