gator experienced in laboratory animal care. The plan 
outlined in Figure 2 is a summary of the administrative 
structure considered desirable by the site visitors, 
based on their visits to 58 institutions. Since this 
figure is a chart of specific duties, in smaller animal 
care organizations, the same duties may be partially 
combined and performed by fewer individuals. Obviously, 
this schematic arrangement may require adjustment for 
each institution; however, the basic pattern of the

should be kept small, if possible. The committee struc-

laboratory animal maintenance colonies and service 
areas should be physically centralized within a re-
