Kine Henry V., v. 2, 148. 
Your wife is your ape, and that heavy burden, wedlock, 
your Jack an ape’s clog.

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 
good to feeble teeth and wagging, and strengtheth and 
fasteneth 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

while the virtue that is hid within is unknown. And this 
stone is kindled in water, and quenched in oil, and that is 
wonder. Bartholomew (Berthelet), bk. xvi. § 49.

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.
