  In this paper, it is shown that for an $n$-dimensional spherical unit speed
curve $\gamma: I\to S^n$, a given point $P \in S^n$ and a point $s_0$ of the
open interval $I$, the spherical orthotomic curve-germ $ort_{\gamma, P}: (I,
s_0)\to S^n$ of $\gamma$ relative to $P$ is $\mathcal{L}$-equivalent to the
spherical pedal curve-germ $ped_{\gamma, P}: (I, s_0)\to S^n$ of $\gamma$
relative to $P$ (resp., the spherical dual curve-germ ${\bf u}_n: (I, s_0)\to
S^n$ of $\gamma$) if and only if $P\ne \pm{\bf u}_n(s_0)$ (resp., if $P=
\pm{\bf u}_n(s_0)$).
