Treatise on Poisons by Sir Robert Christison

10. _Inflammation of the Peritonæum_, or lining membrane of the belly,

will not require many remarks. When acute, it is rarely attended in its early stage by vomiting; rarely also by irregular action of the intestines, and never by diarrhœa; and it is at once distinguished in the dead body by unequivocal marks of peritonæal inflammation, which are very seldom caused by irritant poisons.[174]
