is seen in our extracts, which recall, too, in their insistence on bleeding the "head vein," Juvenal's remark on his friend about to marry: "O medici, mediam pertundite venam." Some space has already been devoted (p. 28) to the physiology of the human body, but this chapter would not be complete if we did not devote some space to the explanations given of the working of the heart, veins, and arteries, at a time when the circulation of the blood was unknown. It may not be amiss to remind the reader that arteries carry blood from the heart, to which it is returned by the veins, after passing through a fine network of tubes called the capillaries. Turning to what may be called the popular physiology of the time, we may note the change, since mediaeval times, in the allocation of properties to the organs of the body. In our days, the heart and brain set aside, we find no organ mentioned in connection with the various faculties of the body, while up to Shakespeare's time each organ had its passion. Some of these emotions have much changed their seats. True love, which now reigns over the heart, then took its rise in the liver. The friar in "Much Ado about Nothing" says of Claudio, "If ever love had interest in his liver"; and the Duke in "Twelfth Night," speaking of women's love, says: "Alas, their love may be call'd appetite, No motion of the liver, but the palate." The heart, on the other hand, was considered as the seat of wisdom. The spleen is now almost a synonym for bitterness of spirit, but it used to be regarded as the source of laughter. Isabella in "Measure for Measure," after the well-known quotation about man dressed in a little brief authority who plays such apish tricks as make the angels weep, says they would laugh instead if they had spleens: "Who, with our spleens, Would all themselves laugh mortal." The brain in mediaeval times was regarded only as the home of the "wits of feeling"--the senses. Some other points of interest in mediaeval medicine are the strange remedies prescribed, and the way in which they were hit upon. The Editor has not made many selections to illustrate this, nor has he sought out the most strange. And lastly, in this, as in most of the other chapters, much may be learnt of the customs of the time from the indications of the text.
