KING HENRY V., v. 2, 148. 



YOUR wife is your ape, and that heavy burden, wedlock, 

 your Jack an ape's clog. 



<Dekker, "Patient Grissell," line 814. 



HE would sit upon's tail before [my enemies], and frown 

 like John-a-Napes when the Pope is named.

 Jet. 



MERCHANT OF VENICE, iii. I, 42. 



JET is a boisterous \_Bartbolmew rudis~\ stone, and never- 

 theless it is precious. Most plenty and best be in Britain. 

 And is double, that is to say, yellow and black. The black 

 is plain and light, and burneth soon in fire, and driveth 

 away adders with smell thereof, when it is kindled. This 

 giveth monition of them that have fiends within them ; 

 and is holden contrary to fiends ; and giveth knowledge 

 of maidenhead, for if a maid drink of the water thereof, 

 non urinabit, and if she be no maid and drinketh thereof, 

 urinabit anon and also against her will ; and so by this 

 stone a maiden is anon proved. Also the power thereof is 

 ood to feeble teeth and wagging, and strengtheth and 



teneth them. Also it is said that this stone helpeth for 

 fantasies, and against vexations of fiends by night ; also it 

 helpeth against witch-craft, and fordoeth [hinders] hard en- 

 chantments. And so, if so boisterous a stone doth so great 

 wonders, none should be despised for foul colour without, 

 while the virtue that is hid within is unknown. And this 

 stone is kindled in water, and quenched in oil, and that is 

 w nder. Bartholomew (Berthelet\ bk. xvi. 49. 



EVEN to this day there is some plenty to be had of this 

 commodity in Derbyshire and about Berwick, whereof rings, 

 salts, small cups and sundry trifling toys are made. The 

 German writers confound it with amber as if it were a 

 kind thereof [because of its electrical property]. Charles IV.
