    slight as to create only a kind of tremulous motion of the part affected, but at other times it is very intense. It may be also remarked, that the intensity of the contrac¬ tion varies in different parts of the body, as much as its dura¬ tion. Thus the spasmodic contraction of the stomach is of short duration, but that of the gullet frequently lasts for many weeks. This contraction of the middle of the stomach has been no¬ ticed by many anatomists. Mr William Cowper has described, (in his explanation of his 34th plate), what he has named “ two bunches in the lower part of the stomach, and Schneider and Blasius have made men¬ tion of cases, in which the stomach has been divided into three sacs. Riolan, Blasius, Morgagni, Larry, Walter, Ludwig, Hufeland, and Vander Kolk, have also described the contraction in the middle of the stomach. This contraction is either temporary or permanent; and, according to Morgagni, is con¬ nected with a derangement in the functions of digestion. It is most obvious in those instances where the stomach has at¬ tained an unusual size, and is probably only the result of that spasmodic counter action, which takes place at the moment of death, for, after the lapse of 24 hours, it goes off, unless it be the effect of disease; which holds true, also, with respect to the intestinal canal, the gall bladder, and bladder of urine. The contraction in the middle of the stomach does not invari¬ ably go off; for in this, as in other instances, the temporary stricture sometimes lays the foundation of a permanent one. Stricture sometimes takes place in the lower portion of the smaller intestine, but much more frequently in the lower por¬ tion of the larger intestine. In a few cases the bladder of urine is so contracted as to form several sacs. We frequently meet with different por¬ tions of the bladder contracted around small stones; and the constriction is so very great, that the passage between the open cavity of the bladder, and the cyst containing the stone, is re¬ markably small. I have seen it of so small a size, as only to be capable of containing a hog’s bristle. There is no peculiar portion of the bladder in which these
