Oil of almonds, with as much camphor
as can be dissolved in it, applied as a liniment rubbed on the region of
the bladder and perinaeum, and repeated every four hours, was used in this
disease with success by Mr. Latham. Med. Comment. 1791, p. 213.

7. _Accumulatio alvina._ An accumulation of feces in the rectum, occasioned
by the torpor, or insensibility, of that bowel. But as liquids pass by
these accumulations, it differs from the constipatio alvi, which is owing
to too great absorption of the alimentary canal.

Old milk, and especially when boiled, is liable to induce this kind of
costiveness in some grown persons; which is probably owing to their not
possessing sufficient gastric acid to curdle and digest it; for as both
these processes require gastric acid, it follows, that a greater quantity
of it is necessary, than in the digestion of other aliments, which do not
previously require being curdled. This ill digested milk not sufficiently
stimulating the rectum, remains till it becomes a too solid mass. On this
account milk seldom agrees with those, who are subject to piles, by
inducing costiveness and large stools.

M. M. Extract the hardened scybala by means of a marrow-spoon; or by a
piece of wire, or of whale-bone bent into a bow, and introduced. Injections

months. Aloes. An endeavour to establish a habit of evacuation at a certain
hour daily. See Class I. 1. 3. 5.

ORDO III.

_Retrograde Sensitive Motions._

GENUS I.

_Of Excretory Ducts._

The retrograde action of the oesophagus in ruminating animals, when they
bring up the food from their first stomach for the purpose of a second
mastication of it, may probably be caused by agreeable sensation; similar
to that which induces them to swallow it both before and after this second
mastication; and then this retrograde action, properly belongs to this
place, and is erroneously put at the head of the order of irritative
retrograde motions. Class I. 3. 1. 1.

SPECIES.

1. _Ureterum motus retrogressus._ When a stone has advanced into the ureter
from the pelvis of the kidney, it is sometimes liable to be returned by the
retrograde motion of that canal, and the patient obtains fallacious ease,
till the stone is again pushed into the ureter.

2. _Urethrae motus retrogres
