with this apparatus. In the following run, which lasted for 8 hours, considerableproduct collected, and the yield seemed to be in proportion tothe natural gas used. The next runs were made after sweepingthe apparatus with chlorine. After natural gas and chlorinewere both added, the reaction proceeded smoothly and it wasfinally stopped by admitting chlorine alone. The productamounted to 14 cc. from about 10 liters of natural gas; this waspurified and fractionated, and was found to consist of carbontetrachloride and a small amount of chloroform and hexachlore-thane. From the next experiments, an outlet siphon for the hydro-chloric acid produced and an inlet tube for natural gas wereprovided in the receiver. The apparatus was completely filledwith chlorine, but no heat was used in the circuit. About 4 litersof natural gas were used in each run, and considerable productwas obtained; the product was not separated owing to the factthat it was in part distributed throughout the apparatus. It

Attempts were made toascertain whether the ultra-violet rays have any influence onthe reaction between chlorine and methane. Beginning withdaylight, the ultra-violet source was then started and observa-tions were made on the speed of the reaction. As in the precedingexperiments, the issuing natural gas was saturated with waterby passage through a water bottle. Ho
