r ileus, as perpetual vomiting and fever
attend this. Fourthly, it is distinguished from cholera, because that is
accompanied with both vomiting and diarrhoea. And lastly, from the colica
epileptica, or hysteric colic, as that is liable to alternate with
convulsion, and sometimes with insanity; and returns by periods.

M. M. Spirit of wine and warm water, one spoonful of each. Opium one grain.
Spice. Volatile alcali. Warm fomentation externally. Rhubarb.

8. _Colica saturnina._ Colic from lead. The pain is felt about the navel,
is rather of an aching than acute kind at first, which increases after
meals, and gradually becomes more permanent and more acute. It terminates
in paralysis, frequently of the muscles of the arm, so that the hand hangs
down, when the arm is extended horizontally. It is not attended with fever,
or increase of heat. The seat of the disease is not well ascertained, it
probably affects some part of the liver, as a pale bluish countenance and
deficiency of bile sometimes attends or succeeds it, with consequent
anasarca; but it seems to be caused immediately by a torpor of the
intestine, whether this be a primary or secondary affection, as appears
from the constipation of the bowels, which attends it; and is always
produced in consequence of the great stimulus of lead previously used
either internally for a length of time, or externally on a large surface.

A delicate young girl, daughter of a dairy farmer, who kept his milk in
leaden cisterns, used to wipe off the cream from the edges of the lead with
her finger; and frequently, as she was fond of cream, licked it from her
finger. She was seized with the saturnine colic, and semi-paralytic wrists,
and sunk from general debility.

A feeble woman about 40 years of age sprained her ancle, and bruised her
leg and thigh; and applied by ill advice a solution of lead over the whole
limb, as a fomentation and poultice for about a fortnight. She was then
seized with the colica saturnina, lost the use of her wrists, and gradually
sunk under a general debility.

M. M. First opium one or two grains, then a cathartic of senna, jalap, and
oil, as soon as the pain is relieved. Oleum ricini. Alum. Oil of almonds. A
blister on the navel. Warm bath. The stimulus of the opium, by restoring to
the bowel its natural irritability in this case of painful torpor, assists
the action of the cathartic.

9. _Tympanitis._ Tympany consists in an elastic tumor of the abdomen,
