7. Dysentery.
8. Colic.
9. Cholera morbus.
10. Diarrhœa.
In deriving all the above forms of disease from miasmata, I do not mean to insinuate, that sporadic cases of each of them are not produced by other causes.
In designating them by a single name, I commit no breach upon the ancient nomenclature of medicine. The gout affects not only the blood-vessels and bowels, but every other part of the body, and yet no writer has, upon that account, distinguished it by a plural epithet.
The four last of the forms of disease, that have been mentioned, have been very properly called intestinal states of fever. They nearly accord, in their greater or less degrees of violence and danger, with the first four states of fever which occupy the blood-vessels, and in the order in which both of them have been named. I shall illustrate this remark by barely mentioning the resemblance of the yellow fever to the dysentery, in being attended with costiveness in its first stage, from a suspended or defective secretion or excretion of bile, and in terminating very generally in death, when not met by the early use of depleting remedies.
The variety in the forms and grades of the summer and autumnal disease, in different seasons, and their occasional changes into each other in the same seasons, are to be sought for in the variety of the sensible and insensible qualities of the atmosphere, of the course of the winds, and of the aliments of different years.
