Mr. William Sutherland on the 



calculation described as the fifth to all Schiff's data, we obtain 

 ample material for generalization, which can be supplemented 

 by values calculated by the other methods. 



In the following Table the units are again the megamega- 

 dyne, grin., and cm. For brevity the radicals methyl, ethyl, 

 and propyl, &c, will be denoted by the first two ietters of 

 their names, while the acid radicals --formic, propionic, &c. — 

 will be denoted by Fot, Prt, and so on, so that PrPrt stands 

 for propyl propionate. The numbers entered under the 

 heading S will be explained when we are discussing the law 

 of WL
