384- Mr. B. C. Broclie on the Chemical Nature 



over the substance kept melted in a flnsk by means of a water- 

 bath. The gas was dried. The action is slow, and the ex- 

 periment takes several days. When no more action was per- 

 ceived, the substance was boiled with water, dried in a water- 

 bath, and analysed. 



I. 0-394 grm. of the substance gave 0'5435 C0 2 , and 

 169 HO. 



II. 0*4404 grm. of the substance gave 0*6120 C0 2 and 

 0-186 HO, giving in 100 parts-

III. 0*667 grm. of the substance gave 1*489 grm. of chlo-

It is very difficult to tell with certainty when the action of 

 the chlorine on the substance ceases, and I have therefore 

 written the fractional equivalents, which agree rather more 



rci 



closely with the analyses than the whole numbers, C. 4 ^ u, 13 2 . 



The analysis determines with certainty that the substance 

 no longer belongs to the alcohol type; for the addition of two 

 equivalents of hydrogen to the formula would require above 

 0*3 per cent, more hydrogen than the quantity found, a kind 

 of error which is highly improbable.
