*  With  litmus  and  lacmoid  the  solutions  were  all  rendered  blue,  and  changed  only  slightly 
on  adding  the  alkaline  solution.  One  drop  of  the  solutions  was  equivalent  to  about  one-twen- 
tieth of  1  c.c.  Eight-tenths  of  1  c.c.  of  ^  acid  under  absolute  alcohol  may  appear  small  to 
some,  but  when  calculated  to  the  basis  of  a  centinormal  solution  it  means  8  c.c.
