In yangming disease with tidal fever and slightly hard stool, Major Qi-Ordering Decoction may be given; if the stool is not hard, it is not given. If there has been no stool for six or seven days and dry dung is feared, the way to find out is to give a little Minor Qi-Ordering Decoction. If after it enters the abdomen gas passes down, there is dry dung and it may be attacked. If no gas passes, only the first part is hard and the rest will be loose; it must not be attacked, for attacking brings fullness and inability to eat. If the patient wants water, giving it causes retching; if fever comes afterwards, the stool will be hard again and scanty, and Minor Qi-Ordering Decoction harmonises it. When no gas passes, it must by no means be attacked.
燥屎之辨，全在「轉失氣」三字：一探再探，然後敢攻。
病人不大便五六日，繞臍痛，煩燥，發作有時者，此有燥屎，故使不大便也。
病人不大便五六日，绕脐痛，烦燥，发作有时者，此有燥屎，故使不大便也。

When the patient has had no stool for five or six days, with pain around the navel and irritation coming at fixed times, there is dry dung, and that is why there is no stool.
繞臍痛、發作有時，是燥屎自顯之候，不待問也。
陽明病，讝語，有潮熱，反不能食者，胃中必有燥屎五六枚也。若能食者，但鞕爾，宜大承氣湯下之。

In yangming disease with delirious speech and tidal fever, if the patient cannot eat, there must be five or six pieces of dry dung in the stomach. If he can eat, it is hardness only, and Major Qi-Ordering Decoction should be given to purge it.
能食與不能食，判鞕與燥屎：一攻一緩，在此一問。
大下後，六七日不大便，煩不解，腹滿痛者，此有燥屎也。所以然者，本有宿食故也，宜大承氣湯。

After a great purgation, with no stool for six or seven days, unrelieved irritation, and full, painful abdomen, there is dry dung. The reason is previous retained food, and Major Qi-Ordering Decoction is suitable.
宿食不盡，則下後仍有燥屎；攻之不可一而止。
