715. Joy causeth a cheerfulness and vigour in the 

 eyes, singing, leaping, dancing, and sometimes tears. 

 All these are the effects of the dilatation and coming 

 forth of the spirits into the outward parts ; which mak- 

 eth them more lively and stirring. We know it hath 

 been seen that excessive sudden joy hath caused pres 

 ent death, while the spirits did spread so much as they 

 could not retire again. As for tears, they are the ef 

 fects of compression of the moisture of the brain, upon 

 dilatation of the spirits. For compression of the spirits 

 worketh an expression of the moisture of the brain 

 by consent, as hath been said in grief. But then in 

 joy, it worketh it diversely ; viz. by propulsion of 

 the moisture, when the spirits dilate and occupy more

 the heart ; which, to refresh themselves, call in more 

 spirits from the outward parts. And if the paleness 

 be alone, without sending forth the colour again, it is 

 commonly joined with some fear ; but in many there is 

 no paleness at all, but contrariwise redness about the 

 cheeks and gills ; which is by the sending forth of the 

 spirits in an appetite to revenge. Trembling in anger 

 is likewise by a calling in of the spirits ; and is com

 caused, both by a dilatation of the spirits by over-heat 

 ing, and by a liquefaction or boiling of the humours 

 thereupon. Foaming at the mouth is from the same 

 cause, being an ebullition. Stamping, and bending
