This is the [?] method given and supposed, by the authors ([?] + [Marcus]), to be the quickest, most direct method as well as [?] accurate. 
The solution containig the salts of the two metals is made nearly neutral and it is about 15 [?] of a solution of equal parts concentrated hydrochloric acid and ether are added. This solution should not [now] exceed 20 - 30 cc. Hydrochloric acid gas is now passed through to saturation and 5 cc of ether added to secure perfect [?]bility of the two Solutions. Hydrochloric acid gas is again passed through to saturation. (The dish containing the solution is keep cool by a stream of running [?]). The precipitate, of aluminium chloride crystals, is tranferred to an asbestos [?] + washed with a solution of concentrated hydrochloric acid and ether saturated with hydrochloric acid gas at 15°C.
