I.- That the new crime does not serve as an adequate means to commit the principal one;

II.- That the former is not a necessary or natural consequence of the latter, or of the agreed means;

III.- That they did not know beforehand that the new crime was going to be committed, and

IV.- That they were not present at the execution of the new crime, or that, having been present, they did everything on their part to prevent it.
