THE STRUCTDRE OF THE NUCLEUS. 



15. Mttliyl alcohol. — The first sei'ies of lesiilts for methyl alcohol, table 9, 

 were obtained without drying the air. Though the initial plane was not depressed 

 for the i-eivsou given in the preceding paragiaph, tests for its mean position are

given at the beginning of the table. These results differ consi(leraV)ly from table 

 10 in which the air admitted was first dried in the manner shown in § 8. A high 

 initial plane is again evidenced. Of. figure 8.
