As a 'light-note,' here is a recent picture of Matilda who is
Dr. Stone's chief office assistant.  One can see that Matilda
is proudly wearing her "Spy" cap, which came from
the International Spy Museum, located in Washington, DC.
Matilda is usually present when work on PSSPQ testing is
taking place.  She is currently 12 and a half years of age and
follows [and assists] Dr. Stone just about wherever he goes.
Life without Matilda is dreaded, she is like no other
dog that the Stone family has ever had.
