William devotes six chapters to the diseases of the eyes and the eyelids. Then there are two chapters on affections of the ears. Foreign bodies and an accumulation of ear wax are removed by means of instruments. A polyp is either cut off or its pedicle bound with a ligature, and it is allowed to shrivel. The next chapter is on the nose. Nasal polyps were to be grasped with a sharp tenaculum, _cum tenacillis acutis_, and either wholly or partially extracted. Ranula was treated by being lifted well forward by means of a sharp iron hook and then split with a razor. It is evident that the tendency of these to fill up again was recognized, and accordingly it was recommended that vitriol powder, or alum with salt, be placed in the cavity for a time after evacuation in order to produce adhesive inflammation. In the same chapter on the mouth one finds that William did not hesitate to perform what cannot but be considered rather extensive operations within the oral cavity. For instance, he tells of removing a large epulis and gives an account in detail of the case. To quote his own words: "I cured a certain woman from Piacenza who was suffering from fleshy tumor on the gums of the upper jaw, the tumor having grown to such a size above the teeth and the gums that it was as large or perhaps larger than a hen's egg. I removed it at four operations by means of heated iron instruments. At the last operation I removed the teeth that were loose with certain parts of the jawbone." In the next chapter there is an account of the treatment of a remarkable case of abscess of the uvula. In the following chapter the swelling of cervical glands is taken up. In his experience expectant treatment of these was best. He advises internal medication with the building up of the general health, or suggests allowing the inflamed glands to empty themselves after pustulation. After much meddlesome surgery we are almost back to his methods again. He did not hesitate to treat goitre surgically, though he considered there were certain internal remedies that would benefit it. In obstinate cases he suggests the complete extirpation of cystic goitre, but if the sac is allowed to remain it should be thoroughly rubbed over on the inside with green ointment. He warns about the necessity for avoiding the veins and arteries in this operation, and says that "in this affection many large veins make their appearance and they find their way everywhere through the fleshy mass."
