"They use in their diseases various kinds of medicines, so different from any in vogue with us that we are astonished that any escaped. I often saw, for instance, that when a person was sick with a fever, which was increasing upon him, they bathed him from head to foot with cold water, and making a great fire around him, they made him turn round in a circle for about an hour or two, until they fatigued him and left him to sleep. Many were cured in this way. They also observe a strict diet, eating nothing for three or four days. They practise blood-letting; not on the arm, unless in the arm-pit, but generally taking it from the thighs and haunches. Their blood or phlegm is much disordered on account of their food, which consists mainly of the roots of herbs, of fruit, and fish. They have no wheat or other grain, but instead make use of the root of a tree [shrub] from which they manufacture flour, which is very good and called _huca_ [yucca]; the flour from another root is called _kazabi_, and from another _igname_. "They eat little meat except human flesh, and you will notice that in this particular they are more savage than beasts, because all their enemies who are killed or taken prisoners, whether male or female, are devoured with so much fierceness that it seems disgusting to relate, much more to see it done, as I, with my own eyes, have many times witnessed this proof of their inhumanity. Indeed, they marvelled much to hear us say that we did not eat our enemies. "And your Excellency may rest assured that their other barbarous customs are so numerous that it is impossible herein to describe them all. As in these voyages I have witnessed so many things at variance with our own customs, I prepared myself to write a collection, which I call _The Four Voyages_, in which I have related the major part of the things I saw as clearly as my feeble capacity would permit. This work is not yet published, though many advise me to publish it. In it everything will appear minutely, therefore I shall not enlarge any more in this letter, because in the course of it we shall see many things which are peculiar. Let this suffice for matters in general.
