My first glance is always at a woman's sleeve.

In a man it is perhaps better first to take the knee of the trouser.

As you observe, this woman had plush upon her sleeves, which is a most useful material for showing traces.

The double line a little above the wrist, where the typewritist presses against the table, was beautifully defined.

The sewing-machine, of the hand type, leaves a similar mark, but only on the left arm, and on the side of it farthest from the thumb, instead of being right across the broadest part, as this was.
