has been due to the eccentricities of the artistic temperament or a 

 press of other engagements is not known, but it is believed that the 

 beauty of the result will compensate for the delay. The new medal

 the portrait of Hayden on the obverse being much more accurate than 

 could have been hoped for from the photographs available, while the 

 design of the reverse, replacing the unsatisfactory view of the Grand

 Mr. Fox has rendered effective assistance in the issue and distribu- 

 tion of the Proceedings.
