some of which were, undoubtedly, taken from the Siberian

Emeralds of surpassing beauty are said to be found in the
rich collection at Constantinople ; one faultless gem, weighing
three hundred carats, is set in the handle of a poniard ; another,
whose genuineness has been questioned, weighs one hundred
