reserued for some noble prince or worthie man, thereby to make himselfe
rich, and the world happie: desiring you to accept in good part this briefe

And a precise order to pricke the sea card, together with certaine
infallible rules for the shortning of any discouery, to know at the first

[Sidenote: Pereas qui vmbras times.] And therefore to giue me leaue without
offence, alwayes to liue and die in this mind, That he is not worthy to
