《明史·志·卷六十八》
马亏欠不过交纳白银二两，已经生育的已经上报官府，而又死掉的，不过交纳白银三两，产出不死就要挨饿。
马亏欠不过纳银二两，既孳生者已闻官，而复倒毙，不过纳银三两，孳生不死则饥饿。
If a horse goes missing, the owner only has to make a payment of 2 taels of silver. If the foal has already been reported to the authorities but dies, only 3 taels of silver have to be paid. Foals that have been born but do not die are left to starve to death.
