  We study the superconducting properties of the non-centrosymmetric compound
LaNiC$_2$ by measuring the London penetration depth $\Delta \lambda (T)$, the
specific heat $C(T,B)$ and the electrical resistivity $\rho (T,B)$. Both
$\Delta\lambda (T)$ and the electronic specific heat $C_e(T)$ exhibit
exponential behavior at low temperatures and can be described in terms of a
phenomenological two-gap BCS model. The residual Sommerfeld coefficient in the
superconducting state, $\gamma_0(B)$, shows a fast increase at low fields and
then an eventual saturation with increasing magnetic field. A pronounced upturn
curvature is observed in the upper critical field $B_{c2}(T)$ near $T_{c}$. All
the experimental observations support the existence of two-gap
superconductivity in LaNiC$_2$.
