#### Books

In his will, Briggs directed that all his books and bedding be sold with the proceeds divided amongst members of his family, except for a number of named books specifically bequeathed: "Thuarius his Historie in five volumes and Sir Wal[ter] Raleigh his Historie which I give to my ... friend Mr Henrye Gellybrand who gave them to me ... Ptolomye his Geographie and a part of Mercator his great Atlas and Petavius de emendatione temporu[m] in two volumes and ... my own Logarithmes bound and Vlackes Logarithmes all which I give to the Mathematicall Librarie here at the publique schooles.
