He declares the loss of hair and the diarrhœa of phthisis to be fatal signs, and his description of hydrothorax, or dropsy of the chest, has been highly praised by the greatest authorities. He says that phthisis is most common between the ages of eighteen and thirty-six (see _Hippoc. de Morbis_, ii. 45; _Coacæ Prænat., et alibi_). For pleurisy his treatment is practically the same as that followed at the present day. He advised the administration of flour and milk in diarrhœa—an exceedingly useful remedy—and treated the pains of colic by warm injections, warm baths, fomentations, soporifics and purgatives, as the case might require. He was wise enough to know that stone of the bladder was a product of a morbid condition of the urine, and said that when it had fairly formed nothing but an operation for its removal was of any value. He recognised the disease known as hydatids of the liver, and directed that abscesses of that organ should be opened by the cautery. His account of the causes and treatment of dropsy is fairly accurate according to our present knowledge. He approved of paracentesis abdominis (tapping) in cases of ascites, and describes the operation. He recognised the incurability of true cancer. Many of his treatises on the disorders of women prove that they were well understood in his day, and on the whole were properly treated. Difficult labour was managed not so differently from our modern methods as might be supposed. His account of hip-joint disease is remarkably accurate. Gout was well understood by our author, and probably his treatment by purgation and careful dieting was on the whole as successful as our own.
