DAL 



DAN 



tigatedthe subject with the utmost care, 

 and shews, upon seemingly incontestable 

 evidence, that the word is applied always 

 to human spirits. From the arguments 

 adduced by the same author, it should 

 appear that all persons, spoken of as 

 possessed with devils in the New Testa- 

 ment, were eitber deranged or epileptic, 

 and in the same condition with madmen 

 and epileptics of modern days. 



DAFFODIL, the same with the narcis- 

 sus of botanists. 



DAGYSA, in natural history, a genus 

 of the Vermes Mollusca. Generic cha- 

 racter : body loose, nayant, angular, tu- 

 bular, and open at each extremity. One 

 species, viz. D. notata, found in the Spa-

DANCE, or DAXCING. The causes 

 which produce the active operation of 

 dancing are as completely inherent in 

 the human system, as any of those which 

 are generally called involuntary affec- 

 tions of the nerves. A review of "the his- 

 tory of mankind will serve to prove, that 

 the passions are expressed by the same 

 disposition of the muscles in every quar- 

 ter of the globe, and that joy has produc- 

 ed an inclination to dance throughout the 

 individuals of nations, who know not of 

 each other's existence. In the very early 

 ages of the wor^d, before civilization had 

 polished the ideas, sudden joy may be 

 supposed to have been almost the only 

 stimulus to dancing, and this supposition 

 is corroborated by present observation ; 

 the moderns have, indeed, so far refined 

 their feelings, that their disposition to 

 leap or skip with joy is confined to the 

 minuet step in walking, which may be 

 frequently discovered when the features 

 express pleasure. On the contrary, the 

 rude child of nature, endued with nerves 

 of exquisite sensibility, having obtained 

 some desired object, received that inex- 

 plicable shock, which the Divinity hath 

 decreed man shall not fully comprehend ; 

 immediately the subtle pleasure extend- 

 ed to every fibre of his frame, and the 

 convulsive motion became a dance ; as 

 joy is communicable, his family were in- 

 spired, his neighbours caught the infec- 

 tion, and the manner of this first dance
