certain salts of po y the action of bromid of elayl upon acetate 
of potash, the author succeeded in preparing acetate of elayl in considera- 
ble quantity. The id and acetate are to be dissolved in equal quan- 
warmed, when y 
less liquid, almost free from odor. e pure mercur-ethyl CaHsHg boils 
between 158° and 160° C, It takes fire easily and burns with a ]uminous, 
9°97, its calculated density for 2 vols. would be 8°68. 
e author also obtain @ same compound by the action of zinc- 
lead. It appears to be incapable of forming salts without a partial de- 
composition, but the author obtained a crystalline chlorid and sulphate.
