have no mistress, are ashamed to appear virtuous, and must be somehow
masked or disguised, in order to countenance the way of the world.
As, all this is night-work, they have an established rule to avoid
quarrels, by never speaking to or noticing each other, when going in
quest of or to visit their ladies.

In short, the fore-part of every night in the year is a kind of
masquerade. Among people of any rank who do not keep calashes, one
couple never walks close behind another, but each at the distance
of at least twelve paces, to prevent the overhearing of any secret
whispers. Should a lady drop a fan or any thing else by accident, a
gentleman may take it up, but he must not give it to the lady, but to
the gentleman who accompanies her, lest she may happen to be the wife
or sister of him who takes it up; and as all the ladies are veiled,
these wise rules are devised to prevent any impertinent discoveries.
Any freedom in contravention of these laws of gallantry would be
looked upon as the highest affront, and would be thought to merit a
drawn sword through the midriff. Should any one see his most intimate
friend any where with a woman, he must never take notice of it, or
mention it afterwards. Every thing of this nature is conducted with
all imaginary gravity and decorum, by which the practice of gallantry
becomes decent and easy; yet there are some jealousies in this regular
commerce of love, which sometimes end fatally. A story of this kind
happened shortly before I went to Lima. A young lady, who thought
herself sole sovereign in the heart of her lover, saw him by chance
in the company of another, and, waiting no farther proof of his
infidelity, she instantly plunged a dagger in his bosom. She was soon
after brought to trial, and every one expected that she should pay
the forfeit with her life; but the judges, considering her rashness
as proceeding from excess of love, not malice, acquitted her. However
