       I have a two dimensional list (i.e. {{1, 23}, {2, 24}, {3, 25}, 
{4, 26}}), and I want to remove all the first values in each pair of 
numbers.  For instance, for the first pair, I want it to read {23}, and 
for the second, {24} instead of {2, 24}. 
        Any help would be greatly appreciated.

In[1]:=
Last/@{{1, 23}, {2, 24}, {3, 25},
{4, 26}}
Out[1]=
{23, 24, 25, 26}
