2. New Salts and Reactions of Cesium and Rubidium.—Some 
time ago Goprrrroy described the igo hp in 
ezsium solutions by antimonous chloride. To this he now 
assigns the formula (CsCl) ,SbCl;.) He has continned his inves- 
tigation and now announces that not on antimonous ahtovids, 
but the chlorides of many other metals give, with cesium m salts, 
greeter precipitates, ceed soluble in "hydrochloric acid. 
mentions of these: iron-cesium chloride Fe,Cl,(CsCl), ; 
bis ismuth-cesium chloride, BiCl,(CsCl),; zinc-cesium * chloride, 
ZnCl, (CsCl), ; cadmium-cesium chloride, CdCl,(CsCl), ; mer- 
tt opelor chloride, HgCl,(CsCl),; copper-cesium chloride 
rhe, »(CsCl),; manganese-ceesium chloride MnCl, CsCl), 3 ; and 
ickel-cresium chloride, NiCl,(CsCl),. These salts fall readily as 
Sieeciiitation when the metallic chloride, dissolved in concentrated 
hydrochloric acid, is mixed with a similar solution of caesium 
soluble 
dilute hydrochloric ot oe tN giee out easily on evaporation. 
An investigation was then made the behavior of the other 
alkali-metals and of ammonium with the metallic chlorides above 
loride can used for its winaaesioe: pri 
eight isomeric amy! alcohols, of which fou e primary, three are 
secondary and one is tertiary. These are connetneed as follows :—
