In a grant I have also now before me of Queen Elizabeth--

"Decimas, calchanti, liquor, mineral, metal," &c.

are given to the grantee for a term of twenty-one years: probably your

readers can also enlighten my ignorance of the term _calchanti_; the other

words are obvious. If any authorities are to be met with, probably in the

answers to these queries your correspondents will have the goodness to cite

them.
