Til. Enns with Oxyd of Zinc, as an absorbent of Chlorine in the 
nalysis of substances rich in H ydrogen. 
In these experiments the oxyd of zinc was employed in the 
me manner as above described for the analysis of chloroform. 
The chlorid of amyl, which was the subject of analysis, was 
SS n the usual manner. Its boiling-point was 102°, 8 
corr 
The following results of two analyses with oxyd of zinc indi- 
cate that this oxyd combined with and retained some of the car- 
bonic acid. This result was not anticipated, as in the analysis of 
chloroform the determination of carbon was uniformly slightly 
ay eae 
The results of these two analyses are as follows 
2 gram of chlorid of amyl gave 03513 3 of carbonic 
seid: 0 0° 1854 of water, and 0°2528 of chlorid of silver.
