5 So, too, if a man is trimming a tree, and kills your slave as he passes by with a bough which he lets fall, he is guilty of negligence, if it is near a public way, or a private path belonging to a neighbour, and he does not call out to give people warning; but if he calls out, and the slave takes no pains to get out of the way, he is not to blame. Nor would such a man be liable, if he was cutting a tree far away from a road, or in the middle of a field, even if he did not call out; for strangers had no business to be there.
6 Again, if a surgeon operates on your slave, and then neglects altogether to attend to his cure, so that the slave dies in consequence, he is liable for his carelessness.
7 Sometimes, too, unskilfulness is undistinguishable from carelessness—as where a surgeon kills your slave by operating upon him unskilfully, or by giving him wrong medicines;
8 and similarly, if your slave is run over by a team of mules, which the driver has not enough skill to hold, the latter is suable for carelessness; and the case is the same if he was simply not strong enough to hold them, provided they could have been held by a stronger man. The rule also applies to runaway horses, if the running away is due to the rider's deficiency either in skill or strength.
9 The meaning of the words of the statute 'whatever was of the highest value thereof within the year' is that if any one, for instance, kills a slave of yours, who at the moment of his death is lame, or maimed, or blind of one eye, but within the year was sound and worth a price, the person who kills him is answerable not merely for his value at the time of his death, but for his highest value within the year. It is owing to this that the action under this statute is deemed to be penal, because a defendant is sometimes bound to pay a sum not merely equivalent to the damage he has done, but far in excess of it; and consequently, the right of suing under the statute does not pass against the heir, though it would have done so if the damages awarded had never exceeded the actual loss sustained by the plaintiff.
10 By juristic construction of the statute, though not so enacted in its terms, it has been settled that one must not only take account, in the way we have described, of the value of the body of the slave or animal killed, but must also consider all other loss which indirectly falls upon the plaintiff through the killing. For instance, if your slave has been instituted somebody's heir, and, before he has by your order accepted, he is slain, the value of the inheritance you have missed must be taken into consideration; and so, too, if one of a pair of mules, or one of four chariot horses, or one of a company of slave players is killed, account is to be taken not only of what is killed, but also of the extent to which the others have been depreciated.
11 The owner whose slave is killed has the option of suing the wrongdoer for damages in a private action under the lex Aquilia, or of accusing him on a capital charge by indictment.
12 The second chapter of the lex Aquilia is now obsolete;
13 the third makes provision for all damage which is not covered by the first. Accordingly, if a slave or some quadruped which comes within its terms, is wounded, or if a quadruped which does not come within its terms, such as a dog or wild animal, is wounded or killed, an action is provided by this chapter; and if any other animal or inanimate thing is unlawfully damaged, a remedy is herein afforded; for all burning, breaking, and crushing is hereby made actionable, though, indeed, the single word 'breaking' covers all these offences, denoting as it does every kind of injury, so that not only crushing and burning, but any cutting, bruising, spilling, destroying, or deteriorating is hereby denominated. Finally, it has been decided that if one man mixes something with another's win or oil, so as to spoil its natural goodness, he is liable under this chapter of the statute.
14 It is obvious that, as a man is liable under the first chapter only where a slave or quadruped is killed by express design or through negligence on his part, so, too, he is answerable for all other damage under this chapter only where it results from some wilful act or carelessness of his. Under this chapter, however, it is not the highest value which the thing had within a year, but that which it had within the last thirty days, which is chargeable on the author of the mischief.
