2. When the plaintiff sues for an injury to his relative rights, as for
beating his wife, his child,, or his servant, it is usual to lay the injury
with a per quod. In such case, after complaining of the injury, say to the
wife, the declaration proceeds, "insomuch that the said E F, (the wife,) by
means of the premises, then and there became and was sick, sore, lame, and
disordered, and so remained and continued for a long space of time, to wit,
hitherto, whereby he, the said A B, (the plaintiff,) lost", &c. 2 Chit. Pl.
