Jaundice occasionally occurs in the course of the disease. I have never happened to see this complication, and am inclined to think it is rare in this country. Liebermeister, however, met with it 6 times in 1420 cases, and Griesinger 10 times in 600 cases. Hoffmann found it in 10 of 250 fatal cases, and Murchison was able to collect 9 cases, all of which but one terminated in death. Several of Griesinger's cases, however, ended in recovery. In a few cases the jaundice may be attributed to catarrh of the biliary ducts, but this solution of the question will not explain those cases in which the feces remain colored throughout. In fatal cases marked degeneration of the liver has been found, which Liebermeister regards as of similar character to that which occurs in acute yellow atrophy. In two of Murchison's cases the liver was small and its secreting cells loaded with oil. In most cases it does not appear until late in the disease, but it has been observed as early as the fifth day.

Abscess of the liver and diphtheritic inflammation of the mucous membrane of the gall-bladder are among the rarer sequelæ of typhoid fever.

Peritonitis is the most serious of all the complications of typhoid fever. Its most common cause is perforation of the bowel, but it may also be due to the extension of inflammation to the peritoneal membrane without ulceration. Liebermeister believes that it is sometimes the result of the typhoid infiltration so frequent in various tissues of the body taking place in the serous membrane. In other cases it arises from the rupture of softened mesenteric glands, of softened infarctions in the spleen, or of the abscesses which are sometimes the consequence of the circumscribed inflammation by which perforation is occasionally prevented from proving immediately fatal. Less frequent causes of it are rupture of the gall-bladder, with the escape of gall-stones into the cavity of the abdomen, abscesses of the ovary, and abscesses in the walls of the urinary bladder. It is said by Murchison to have been in one case the result of a pseudo-abscess in the sheath of the rectus muscle bursting inward.

Swelling of the parotid gland occasionally occurs in typhoid fever, but is much less common than in typhus. It is most frequently met with in bad cases about the end of the third week or later, and generally involves one side only. The swelling is hard and firm in the beginning, and may terminate in resolution or suppuration. I have seen it three times only, twice in my own practice, and once in that of a medical friend. One of my cases was fatal, the other ended in recovery, as did, I believe, the third case. Murchison saw it in only 6 cases, 5 of which were fatal. According to Hoffmann,66 16 cases of suppurative parotitis were found at Basle among about 1600 typhoid fever patients, 7 of the 16 ending fatally. Parotitis without suppuration occurred three times. In 15 cases the attack was confined to one side, 9 times to the right and 6 to the left; in 4 it was double. Trousseau67 looks upon these swellings as a very grave accident, and says that he has scarcely ever seen a case recover in which it has occurred, either in the course of typhoid fever or any other disease. Chomel, on the other hand, is said to have regarded them as critical and auspicious.

Menstruation occasionally occurs during typhoid fever, and may be profuse. Bartels,68 who has investigated the histories of 172 patients in reference to this point, says that the catamenia always appear if the menstrual period falls within the first five days of the fever, and that they do so in two-thirds of the cases if they are expected between the sixth and fourteenth days. On the other hand, menstruation does not occur if the time for it falls in the third week. He says also that the catamenia generally appears about the time they are expected, or later, and very seldom earlier. Liebermeister, on the contrary, says that they often occur prematurely. Other uterine hemorrhages seldom occur, and never in those who have ceased to menstruate or in whom the function has not been established.

Suppuration of Bartholini's glands is said by Speilman to have taken place in one case.69 In the fourth week the patient complained of violent pains in the right nympha, which, upon examination, was found to be swollen. A tumor as large as a nut, which was red and painful on pressure, could also be felt in the vagina.
