Test #2 
On September 17, 1962, a second group of cocoons from Y-l was 
isolated in the care of two adult nurses. They ecolosed and matured 
there. 
On March 11, 1963, 17 workers were transferred with clean for¬ 
ceps, as before, back to the main colony. At the most, two of these 
workers (the two nurses) would previously have been exposed to the 
main group. In these tests, there was some low-order alarm as indi¬ 
cated, quickly passing to entire compatibility.
