The following argument is couched in syllogistic form:
If money in the form of silver coin is silver, the man who bequeathed all his silver to a legatee, includes all money in the form of coined silver: but he bequeathed all his silver: therefore he included in the bequest all money in the form of coined silver.But for the orator it will be sufficient to say,
Since he bequeathed all his silver, he included in his bequest all his silver money.
