Sponsor a Book update

The Library thanks Professor Paul Henderson for his donation to the Sponsor a Book Appeal, which has allowed us to restore Rene Just Hauy’s
Traité des caractères physiques des pierres précieuses, pour servir a leur détermination lorsqu’elles ont été taillées [sic].
The 1817 volume was carefully conserved by Aquarius Book Restorers, who replaced the perished calf spine and corners while preserving the original marble boards.
