In the case of: these organic liquids, which absorb the 

 emanation so strongly, the better method to use is Method 2, 

 previously described. Possibly, on account of: the use of 

 rubber tubing instead of stopcocks, the results are not quite 

 so accurate as those in the case of water; the error, if anything, 

 would make the results a little too high. The solubilities are 

 given in Table IV., and refer to 14° C.

These figures suggest the probability that there are some 

 organic liquids which absorb the emanation even more
