acquired the Chorea St. Viti in fo univerfal a manner, that her 

 fpeech became affected as well as her limbs ; and there was evi- 

 dently a difunion of the common trains of ideas ; as the itch 

 was (till among the younger children of the family, (he was ad- 

 vifed to take her filler as a bedfellow, and thus received the itch 

 again ; and the dance of St. Vitus gradually ceafed. See Clafs 

 II. 1. 5. 6. 



M. M. Give the patient the itch again. Calomel a grain 

 every night, or fublimate a quarter of a grain twice a day for a 

 fortnight. Steel. Bark. Warm bath. Cold bath. Opium. 

 Venefection once at the beginning of the difeafe. Electricity. 

 Perpetual flow and repeated efforts to move each limb in the 

 defigned direction, as in the titubatio linguae above defcribed. 



3. Rifus. Laughter is a perpetual interruption of voluntary 

 exertion by the interpofition of pleafurable fenfation ; which not 

 being checked by any important confequences rifes into pain, 

 and requires to be relieved or moderated by the frequent repe- 

 tition of voluntary exertion. See Seel. XXXIV. 1 4. and 

 Clafs III. 1. 1. 4. and IV. 1. 3. 3. 



4. ^Tremor ex ird. The trembling of the limbs from anger. 

 The interruption of the voluntary arlbciations of motions by an- 

 ger, originates from too great a part of the fen forial power being 

 exerted on the organs of fenfe ; whence the mufcles, which ought 

 to fupport the body upright, are deprived of their due quantity, 

 and tremble from debility. See Clafs III. 2. 1. 1. 



5 . Rubor ex ird. Rednefs from anger. Anger is an excefs 

 of averfion, that is of voluntarity not yet employed. It is excit- 

 ed by the pain of offended pride ; when it is employed it be- 

 comes outrage, cruelty, infanity. The cutaneous capillaries, 

 efpecially thofe of the face, are more mobile, that is, more eafi- 

 ly excited into increafed action, or more eafily become torpid, 

 from lefs variation of fenforial power, than any other parts of 

 the fyftem, which is owing to their being perpetually fubject to 

 the vicifTnudes of heat and cold, and of extenfion and corruga- 

 tion. Hence, when an excefs of voluntarity exifts without be- 

 ing immediately expended in the actions of the large mufcles, 

 the capillary arteries and glands acquire more energetic action, 

 and a fluihed (kin is produced, wirh increafed fecretion of per- 

 fpirable matter, and confequent heat, owing to the paufe or in- 

 terruption of voluntaiy a^Hon ; and thus the actions of thefe 

 cutaneous veiTels become aflcciated between the irafcent ideas 

 and irafcent mufcular actions, which are thus for a time inter- 

 rupted. 



C. Ruhor crhninatl. The blu filing of accufed people, wheth- 

 er guilty or not, appears to be owing to circumflances fimilar to
