$^a$ The DLAs at $z$ = 2.81115 toward \object{Q0528--2505}, $z$~= 1.96221 toward \object{Q0551--3637}, and $z$~= 3.09240 toward \object{J2100--0641} exhibit fully saturated \none\ profiles, and $N$~abundances could not be extracted.  \\
$^b$ The triplets used to measure the \none\ absorption: \none\ $\lambda\lambda$ 1134.165, 1134.415, 1134.980 and \none\ $\lambda\lambda$ 1199.550, 1200.223, 1200.710.  \\
$^c$ Nitrogen abundance relative to solar where log~(N/H)$_\odot$~= $-$4.07 \citep{Ho01}. Errors were formed by adding in quadrature the logarithmic errors on $N$(\none), $N$(\hi), and an additional 0.05~dex allowing for uncertainties in the solar nitrogen abundance.  \\
$^d$ Nitrogen-to-silicon ratio.  \\
$^e$ All measurements in this table have been made by us. However, in several cases, [N/H] has been determined previously: 1~\citet{Le08}; 2~\citet{HP07}; 3~\citet{DZ06}; 4~\citet{DZ04}; 5~\citet{Lo02}; 6 \citet{Pe95}; 7 \citet{SP01}. Our results generally agree with previous results within the errors; for the DLA toward \object{Q2348-1444}, our value for log~$N$(\none) is consistent with the upper limit log~$N$(\none)~$<$ 13.48 reported by \citet{Pe95}.
