gous 1 in some degree to the paralysis of the muscles of the arms 

 in colica saturnina. It would seem, that the muscles of the legs 

 in walking get a sympathy with the lower parts of the intestines, 

 and those of the arm in variety of employment obtain a sympa- 

 thy with the higher parts of them. See Cholera and Ileus. 



11. Zona ignea nephritica. Nephritic shingles. The exter- 

 nal skin about the loins and sides of the belly I suppose to have 

 greater mobility in respect to sensitive association, than the ex- 

 ternal membrane of the kidney; and that their motions are by 

 some unknown means thus associated. When the torpor or be- 

 ginning inflammation of this membrane ceases, the external skin 

 becomes inflamed in its stead, and a kind of herpes, called the 

 shingles, covers the loins and sides of the belly. See Class II.

12. Eruptio variolarwn. After the inflammation of the in- 

 oculated arm has spread for a quarter of a lunation, it affects the 

 stomach by reverse sympathy; that is, the actions of the stomach 

 are associated with those of the skin; and as much sensorial 

 power is now exerted on the inflamed skin, the other part of 

 this sensitive association is deprived of its natural share, and be- 

 comes torpid, or inverts its motions. After this torpor of the 

 stomach has continued a time, and much sensorial power is thus 

 accumulated; other parts of the skin, which are also associated 

 with it, as that of the face first, are thrown into partial in- 

 flammation; that is, the eruptions of the small-pox appear on 

 the face. 



For that the variolous matter affects the stomach previous to 

 its eruption on the skin, appears from the sickness at the com- 

 mencement of the fever; and because, when the morbid motions 

 affect the skin, those of the stomach cease; as in the gout and 

 erysipelas, mentioned below. The consent between the stomach 

 and the skin appears in variety of other diseases; and as they 

 both consist of surfaces, which absorb and secrete a quantity of 

 moisture, their motions must frequently be produced together, 

 or in succession; which is the foundation of all the sympathies 

 of animal motions, whether of the irritative, sensitive, or volun- 

 tary kinds. 



Now as the skin, which covers the face, is exposed to greater 

 variations of heat and cold than any other part of the body; it 

 probably possesses more mobility to sensitive associations, not 

 only than the stomach, but than any other part of the skin; and 

 is thence affected at the eruption of the small-pox with violent 

 action and consequent inflammation, by the association of its mo- 

 tions with those of the stomach, a day before the other parts of
