[GAIUS libro septimo ad edictum prouinciale. ] §9.2.8.prIdem iuris est, si medicamento perperam usus fuerit.
[GAIUS, from the seventh book on the Provincial Edict.] The same rule of law applies if one has used a medicine incorrectly.
sed et qui bene secuerit et dereliquit curationem, securus non erit, sed culpae reus intellegitur.
But also one who has operated well and then abandoned the treatment will not be free from liability, but is understood to be guilty of negligence.
mulionem quoque, si per imperitiam impetum mularum retinere non potuerit, si eae alienum hominem obtriuerint, uolgo dicitur culpae nomine teneri.
It is also commonly said that a muleteer is held on the ground of negligence if, through unskillfulness, he could not hold back the onset of the mules, and they crushed another's slave.
idem dicitur et si propter infirmitatem sustinere mularum impetum non potuerit: nec uidetur iniquum, si infirmitas culpae adnumeretur, cum affectare quisque non debeat, in quo uel intellegit uel intellegere debet infirmitatem suam alii periculosam futuram.
The same is said even if, because of weakness, he could not withstand the onset of the mules; nor does it seem unfair if weakness is numbered as negligence, since no one ought to attempt that in which he either understands or ought to understand that his own weakness will be dangerous to another.
idem iuris est in persona eius, qui impetum equi, quo uehebatur, propter imperitiam uel infirmitatem retinere non poterit.
The same rule of law applies in the case of a person who, because of unskillfulness or weakness, cannot hold back the onset of the horse on which he was riding.
