fit for perceiving fuch odours, and is preferred from beino- in- 

 jured by thofe that are more ftrong or corrofive. Many other 

 receptacles of peculiar fluids difgorge their contents, when the 

 ends of their duels are ftimulated ; as the gall bladder, when the 

 contents of the duodenum ftimulale the extremity of the com- 

 mon bile duel: : and the falivary glands, when the termination 

 of their duels in the mouth are excited by the ftimulus of the 

 food we mailicate. Atque veficulx feminales iuum exprim'unt 

 fiuidum glande penis fricata. 



The coldnefs and drynefs of the atmofphere, compared with 

 the warmth and moifture, which the new-born infant had juft 

 before experienced, difagreeably affecl: the aperture of this lacry- 

 mal fack : the tears, that are contained in this fack, are poured 

 into the noftrils, and a further fupply is fecreted by the lacry- 

 mal glands, and diffufed upon the eye-bails ; as is very vifible in 

 the eyes and noftrils of children foon after their nativity. The 

 fame happens to us at our maturer age, for in fevere fro 

 weather, fnivelling and tears are produced by the coldnefs and 

 drynefs of the air. 



But the lacrymal glands, which feparate the tears from the' 

 blood, are fituated on the upper external part of the globes of 

 each eye ; and, when a greater quantity of tears are v i, we 



contract the forehead, and bring down the eye-brows, and ufe 

 many other diftortions of the face, to comprefs thefe glands. 



Now as the fuffocating fenfation, that produces refpiration, is 

 removed almoft as foon as perceived, and does not recur again : 

 this difagreeable irritation of the lacrymal duels, as it muft fre- 

 quently 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 through- 

 out their lives, all difagreeable fenfations are attended with fniv- 

 elling at the nofe, a profufion of tears, and fome peculiar diftor- 

 tions of countenance : according to the laws of early affociation 

 before mentioned, which conilitur.es the natural or univerfal 

 language of grief. 



You may affure yourfelf of the truth of this obfervation, if 

 you will attend to what paftes, when you read a diftrefsful tale 

 alone ; before the tears overflow your eyes, you will invariably 

 feel a titiilation at that extremity of the lacrymal duel:, which 

 terminates in the noftril, then the compreftion of the eyes fuc- 

 ceeds, and the profufion of tears. 



Linnaeus aflerts, that the female bear (beds tears in grief; tl 

 fame has been fai<Tof the hind, and fome other animals.
