A capricious appetite is another of the peculiarities of pregnancy, a longing for unnatural food, so that some women will enjoy eating such things as chalk, slate pencils, and similar indigestible stuff; this I have always considered a form of hysteria, that is, a functional derangement of the nervous system, for which I gave ten grains of bromide of sodium three times a day, with the best results; others again became passionately fond of sour salads, or strong condiments like mustard, Worcestershire sauce, and salt fish, while others again long for fruits. Salivation of the mouth is another very unpleasant symptom which annoys some women when they are pregnant, for they will secrete such enormous quantities of saliva, that they cannot help drooling from the mouth when they speak. In salivation of pregnancy the gums do not become sore as in the salivation from mercury; in the former the irritation is confined to the salivary glands alone. The wonderful sympathy that exists between remotely situated organs of the body is here strikingly illustrated between the sexual organs and the salivary glands in both sexes. In mumps also, which is an inflammation of the salivary gland, it is not unusual for the testes in the male and the mammæ in the female to become swollen and painful, and as soon as this swelling takes place, the inflammation of the salivary gland disappears. The breasts become enlarged and otherwise altered in pregnancy, the enlargement is accompanied with more or less sharply shooting pain, they also become harder and are more movable than otherwise. The nipple becomes more prominent and painfully sensitive, the veins that run from the breast become distended so that they can be readily traced by the eye. The presence of milk in the mammæ is another sign, but that, too, is only presumptive, because the secretion of milk takes place in other conditions than that of pregnancy; even the newly-born infant has sometimes milk in its breasts, and milk has been recognized in the breasts of some males and not infrequently in those of young virgins. Pigmentation or the deposit of coloring matter in pregnancy has long been observed as a prominent symptom and when taken together with other signs it is worthy of careful consideration, but here, too, we encounter the obstacle to anything of a positive nature, for discoloration is also met with in females who are suffering from pelvic diseases and who are not pregnant. Areola is the technical name of that peculiar circle which immediately surrounds the nipple. In a healthy virgin this circle is characterized by a beautiful rose-tinted blush, but under the influence of disease, even in the virgin the circle becomes more or less discolored. When pregnancy has occurred the areola around the nipple becomes darker and darker; other parts of the body become similarly discolored, this occurs on the abdomen and perineum.
