_Perfect Tense._--In Albités' "Companion" to _How to speak French_, one
of the first exercises is to turn into French the following phrase, "I
have seen him yesterday." I should be much obliged to MR. J. S. WARDEN
(to whom all readers of "N. & Q." stand so greatly indebted for his
excellent article on "Will and Shall"), if he would state the rule for
the use of the perfect tense in English in respect to specified time,
and the _rationale_ involved in such rule.
