"The surface of both the visceral and parietal peritoneum was studded over with hundreds of small, firm, whitish nodules, generally not larger than a pea, and often not larger than a pin's head. In some places they had coalesced and made firm patches an inch in extent. This same material was found in the contracted omentum in considerable quantity. In a few places, particularly on the uterus, a blackish pigmented deposit appeared.

"The ovaries were not adherent, but both were enlarged to the size of a hen's egg. The outer surface of each was rough and corrugated. The new growth was deposited on the exterior and penetrated each a quarter to half an inch. It was of uniform white color and of firm consistence.

"The stomach wall was thickened nearly throughout its extent, but particularly in the anterior part, where it amounted to thrice the normal thickness. This consisted wholly of hypertrophy of the muscular coat and increase of fibrous tissue in the peritoneal layer. This new growth was traced, in the interlacing bands, from the surface into the muscular coat. In the outer layer of the stomach were found three small white nodules. The mucous membrane of the organ was healthy or a little pale.

"The retro-peritoneal glands along the aorta were enlarged, soft, and of a reddish-gray color. A nodule was found in the wall of the duodenum outside the mucous membrane, and one in the Fallopian tube."

Every organ in the abdomen and chest was examined, but nothing important found except what is here recorded. Welch concludes his record with the following diagnosis: "Primary scirrhous carcinoma of the ovaries. Secondary deposits in the peritoneum, in the outer layer of the right Fallopian tube, of the stomach and duodenum, and in the retro-peritoneal glands. Chronic peritonitis, intestinal obstruction."

This case presents to the reader so accurately the usual course of cancerous peritonitis, and the inspection its lesions, that a treatise on the subject is hardly called for. It often happens that cancerous antecedents in the patient or his relatives will lend an aid to the diagnosis, which this case did not present. To distinguish this disease from tubercular peritonitis no question can arise except in its dropsical form, and then the lungs in every case of the latter that I have met with have the physical signs of tubercles, though not always the rational indications. The pulse is much more accelerated in the tuberculous variety. I omitted to state that the temperature of this patient was often taken, and till the closing scene was never found more than one or two degrees above the healthy standard, and the morning and evening heat did not materially vary; the opposite of both, then, would be expected in a tuberculous case. The existence of meteorism is much more common in the tubercular disease; indeed, in the cancerous case recited there was none of it. The duration of the two is different—that of the cancerous kind is recorded in months, while the tuberculous variety may continue two years. The cancerous is more likely to be attended by alarming accidents, like the complete obstruction of the bowels, large hemorrhages, and a sudden lighting up of acute peritonitis. Finally, in the light of the case here recorded, it seems probable that the examination of the abdominal fluid will become of great importance. I have never carefully examined the fluid of tubercular dropsy, but it does not seem probable that it will have the syrupy appearance, the large amount of albumen, the abundance of fibrin-fibres, and the granular large cells with nuclei only perceptibly less in size than the cells themselves, that were repeatedly found in this case—found by two observers, and at every tapping after the first.

TREATMENT cannot be curative; it therefore consists of such administrations as will relieve pain, give sleep, improve the appetite, increase the flow of urine if it be scanty, and relieve the bowels if there is a tendency to constipation. It is as much the duty of the physician to put off the fatal day, when he can, in incurable affections as it is to cure those that will yield to his prescription and advice. In the case just narrated opium or an opiate alone produced such unpleasant after-effects that she was unwilling to take it, but when the extract of belladonna was given with it she slept pleasantly, and could take her food the next day.

Infantile Peritonitis, or Peritonitis of Childhood.

Bauer, in Ziemssen's Cyclopædia of Practice of Medicine, and Wardell, in Reynolds's System of Medicine, have each devoted a chapter to this form of disease. They refer to the fact that the foetus may have peritonitis before birth or be born with it, or may have it when a few days old. They say that this form of the disease occurs most frequently in lying-in asylums or foundling hospitals, and that it has been supposed to depend on a syphilitic taint. They say, too, that it follows erysipelas, scarlet fever, measles, etc. I do not perceive that the description of either of these authors makes any marked distinction between this and the same disease in adults, except what may arise from the inability of the infant to describe its sensations, and the more rapid course of the disease to a fatal result—in some cases twenty-four hours. Having myself had no obstetrical practice, or next to none, I have nothing to add to their statements, and can from my own knowledge abate nothing. I therefore refer the reader to these chapters, and to the references given by the first of these authors, for a fuller knowledge of the matter.

Regarding the comparative exemption of children, after the first few weeks of life, from spontaneous peritonitis, referred to by one of these authors, I can fully confirm his statement. Though I have assisted in the treatment of many children suffering from peritonitis, I have difficulty in recalling to mind a single case in which the disease was not caused by perforation of the intestine or vermiform appendix of the cæcum, and in much the greatest frequency perforation of the appendix.
