unknown seas: anyone, I say, who is sensible of these difficulties will
be much more pleased at the discoveries and observations I have been able
to make than displeased with me that I did not make more.

Thus much I thought necessary to premise in my own vindication against
the objections that have been made to my former performances. But not to
