* Dr. Davies observes, that these medals of Queen Elizabeth and Queen Mary 
were, undoubtedly the large Sovereigns of those queens, which were of the old standard 
of England, or of gold appointed to be of 23 car. 3I grs. fine. See Tables of specific 
Gravities, extracted from various Authors, with some Observations upon the same;
