 badge  upon  the  right  shoulder  by  twelve  boys  belonging  to  
 Christ’s Hospital,  for whose  education funds were  furnished by  
 Henry Stone, one  of  the Governors,  and  for which at his death  
 provision was made under his will.

 This and the following medal were executed by John Boettier ;  
 the  dies  are  in  the  British  Museum.  They  were  probably  
 intended  as prizes to pupils of  the Eoyal  Mathematical  School  
 in Christ s Hospital.  As none  have been  found with  rings for  
 suspension,  they could not have been intended to be worn. 
 The  diagrams  on  this  medal  are  to  be  found  in  a  work  
 entitled  “ Modern  Fortification  or Elements of Military Architecture, 
   by Sir Jonas Moore, Master-Surveyor of His Majesty’s  
 Ordnance,  London,  1689.”  The  upper  diagram  represents  
 Moore’s  improved  system  of  constructing  a  fortification  on  a  
 pentagon, founded on the system of Count de Pagan, the eminent  
 French  engineer  and  astronomer :  the  lower one  to  a  similar  
 construction  of  a  fortification  on  a  square.  Sir Jonas  Moore  
 was  one  of  the  Governors  of  Christ’s  Hospital,  and  it  was  
 specially  through  his  instrumentality  that  the  royal  charter  
 for  the  foundation  of  the  Mathematical  School  was  granted.  
 Moore  took  great  interest  in  the  working  of  the  School,  and  
 superintended  personally  the  instruction  given  to  the  pupils.  
 It is,  therefore,  very probable  that  these  medals were  executed  
 under his own direction.

 This diagram  does  not  seem  to  occur  in  Sir Jonas Moore’s  
 work.  I t appears to  give  the rule for  determining the point of  
 the  ravelin  in  a  fortification,  i.e.,  a  triangular  work  of  less  
 elevation  than  the  main  defences,  situated  with  its  salient  
 angle to the front before  the  curtain,  which with  the  shoulders  
 of  the adjoining bastions it  serves to  protect.
