   note: the vegetable food, after the first mastication, enters
         the first stomach r. it afterwards passes into the
         second n, where it is moistened, and formed into
         pellets which the animal has the power of bringing back
         to the mouth to be chewed again, after which it is
         swallowed into the third stomach m, whence it passes
         to the fourth s, where it is finally digested.
