20 NATURAL HISTORY. 



the object moveth, or the medium moveth. And we 

 see that long turning round breedeth the same im 

 agination. The cause of the imagination that things 

 come upon them is, for that the spirits visual them 

 selves draw back ; which maketh the object seem to 

 come on ; and besides, when they see things turn 

 round and move, fear maketh them think they come 

 upon them. The cause that they cannot see things 

 afar off, is the weakness of the spirits ; for in every 

 megrim or vertigo there is an obtenebration joined 

 with a semblance of turning round ; which we see 

 also in the lighter sort of swoonings. The cause of 

 seeing things out of their place, is the refraction of the 

 spirits visual ; for the vapour is an unequal medium ; 

 and it is as the sight of things out of place in water. 

 The cause of seeing things double, is the swift, and 

 unquiet motion of the spirits (being oppressed) to and

 visual, and the motion of tire object, make the same 

 appearances : and for the swift motion of the object, 

 we see that if you fillip a lute-string, it sheweth double 

 or treble.

 than with great. And again, wine sugared inebri- 

 ateth less than wine pure. The cause of the for 

 mer is, for that the wine descendeth not so fast to 

 the bottom of the stomach, but maketh longer stay 

 in the upper part of the stomach, and sendeth va 

 pours faster to the head ; and therefore inebriateth 

 sooner. And for the same reason, sops in wine (quan 

 tity for quantity) inebriate more than wine of itself. 

 The cause of the latter is, for that the sugar doth 

 inspissate the spirits of the wine, and maketh them
