I. 0*486 grm. by the usual method of analysis gave 1*012 

 grm. chloride of silver, containing 0'249 chlorine. 



II. 0*6715 grm. by the usual method of analysis gave 1*3915 

 grm. chloride of silver, containing 0*34-4 chlorine. 



These analyses give as the per-centage of chlorine —

Chlorine . . . 51*40 51 '28 



These analyses lead us to the formula 



Calculated in 100 parts.

Chlor-Cerotic J&ther. 



The last substance has the properties of an acid, and gives 

 with soda a salt almost insoluble in water. I prepared this 

 salt but did not analyse it, as the substance was lost in attempt- 

 ing to dry it on a water-bath, in which case it is decomposed. 

 The compound aether, however, of the acid may be obtained 

 in a similar way to that in which is obtained the compound 

 aether of the cerotic acid itself. The numbers which this 

 aether gave on analysis, taken with those of the chlor-cerotic 

 acid ; and of the cerotic acid, are conclusive as to the formulae 

 of these bodies. The appearance of this aether is similar to 

 that of the acid from which it is derived. 



0*454 grm. gave 0*6815 carbonic acid and 0*214 water, 

 which analysis gives in 100 parts — 



Carbon 40*94 



Hydrogen 5*24 



Oxygen and chlorine . 53*82 



100*00 



0*650 grm. of the substance gave 1*332 grm. of chloride of 

 silver, which contains 0*3294 grm. of chlorine, and corresponds 



to chlorine 50*68 parts per cent.
