tion of the lacrymal duels, as it mud frequently 

 recur, till the tender organ becomes ufed to variety 

 of odours, is one of the firfl pains that is repeatedly 

 attended to : and hence throughout our infancy, 

 and in many people throughout their lives, all dii- 

 agrceable fenfations are attended with fnivelliitg at 

 the nofe, a profufion of tears, and fome peculiar 

 di Portions of countenance : according to the laws 

 of early aflbciation before mentioned, which con- 

 flitutes the natural or univerfal language of grief. 



You may allure yourfelf of the truth of this ob- 

 fervation, if you will attend to what paffes, when 

 you read a diftrelsful tale alone ; before the tears

 the infant enjoys after its nativity, is excited by the 

 odour of its mother's milk. The organ of fmell 

 is irritated by this perfume, and the lacrymal fack 

 empties itfelf into the noftrils, as before explained, and 

 an increafe of tears is poured into the eyes. Any one 

 may obferve this, when very young infants are about 

 to fuck ; for at thofc early periods of life, the fenfation 

 afFecls the organ of fmell, much more powerfully, 

 than after the repeated habits of fmelling has inured 

 it to odours of common ftrength : and in our adult 

 years, the (Ironger finells, though they arc at the 

 lame time agreeable to us, as of volatile ipirits, 

 continue to produce an increased fecretion of tears. 



This pleating fenfation of fmell is followed by the 

 early affedion of the infant to the mother that luc-
