acquired winking ,of the eyes or impediments of fpeech by imita- 

 ting their companions without being confcioiis of it. 



5. Befides the three fpecies of imitations above defcribecl there 

 pnay be lbme aflbciate motions, which may imitate each other in 

 the kind as well as in the quantity of their action ', but it is 

 difficult to diftinguiih them from the aiTociations of motions treat- 

 ed of in Section XXXV. Where the actions of ether perfons 

 are imitated there can be no doubt, or where we imitate a pre- 

 conceived idea by exenion of our locomotive mufcles, as in 

 painting a dragon ; all thefe imitations may aptly be referred to 

 the fources above described of thepropenGty to activity, and the 

 facility of repetition ; at the fame time I do not affirm, that all 

 thofe other apparent fenfitive and irritative imitations may not be 

 refolvable into a/Jbciations of a peculiar kind, in wjiich certain 

 diftant parts of fimilar irritability or fenfibility, and which have 

 habitually acted together, may affect each other exactly with the 

 fame kinds oi motion ; as many parts are known to fympathife 

 in the quantity of their motions. And that therefore they may 

 be ultimately refolvable into aiTociations of ac?non, as defcribe4 

 in Sea, XXXV,
