§ 9. From the Foxes, whether Crass or Brand Foxes, the Beer-bursch is not bound to take a beer challenge; yet can the Brand-fox nachstürzen (that is, command the person who is going to drink before him, to drink twice the quantity that he proposes). Amongst themselves the Foxes have equal rights.
10. No one must accept a challenge of less than half a choppin, or more than four choppins at once. The graduated quantities of the Comment, are a half, a whole, two, three, and four choppins.
11. The interval between the fore and after drinking of each agreed-upon quantity must be no more than five minutes (that is, the accepter must drink his quantity within five minutes after the challenger). And every earlier challenge must be drunk before the latter one.
12. If four choppins are agreed upon, so must the foreswearer or challenger, drink each choppin separately within five minutes of each other; and not till he has drunk these four choppins, must he take a challenge from another person. Also, the challenger must have first drunk his whole contracted quantity before his antagonist is bound to drink his.
13. He who has a challenge of four choppins on his hands, is not bound to take another challenge till that is drunk out.
14. If a challenge is made, and the challenged excuses himself on the plea that he has already four choppins to drink, the challenger is justified in obliging the challenged to show him each of those four allege choppins as he drinks them.
15. If a challenge is given, and the challenged nachstürz, the quantity, (that is, insists that it shall be doubled,) the challenger is obliged to drink the doubled quantity.
16. The challenged may not more than double the quantity proposed by the challenger.
17. The nachstürz become invalid the moment the prescribed quantity exceeds two choppins, except in a challenge à faire.
18. If one pauses during the drinking, leaves a Philistine in the glass, (that is, if he leaves the bottom of the glass still covered with beer,) it is to be considered that he has not drunken his quantity, and he must instantly drink another in the proper manner.
