different kinds of studies. Furthermore, the 
larger professional and technical staff, justified 
by more research studies, helps to solve the 
problem of maintaining a full 24-hour, seven- 
day week of maintenance and observation. 
An investigator who wishes to avail himself 
of LEMSIP's assistance has to submit a proto- 
col for evaluation by the LEMSIP Utilization 
Committee. Prior to submission of a protocol 
the project is, in general, discussed by the in- 
vestigator with LEMSIP staff members who 
may advise on details of feasibility. During the 
past six years no protocol formally submitted to 
the Utilization Committee after such confer- 
ences has been turned down. Most of the proto- 
cols were modified following advice of the Uti- 
lization Committee in the preliminary talks. In 
general, the modifications included selection of 
more appropriate primate species, avoidance of 
the use of endangered species, and changes in 
methodology to make the program compatible 
with techniques utilized in primate animal ex- 
perimentation. Protocols have also been gener- 
ally modified to improve cost effectiveness and 
to permit animal sharing by other programs. 
For the purpose of animal sharing, the ani- 
mal is, in general, assigned to a principal pro- 
gram which also carries all or the major part of 
the cost of animal purchase or maintenance. 
When the Utilization Committee determines 
that other programs can benefit from the use of 
that animal, the owner's permission is re- 
quested, and if obtained, the animal may be si- 
multaneously assigned to another program. 
The course of experimentation is then closely 
monitored by the Utilization Committee to 
avoid any possible conflict between programs 
assigned to the same animal. Due to the under- 
standing and cooperativeness of the community 
and of close supervision of the programs by the 
Utilization Committee, such conflicts have been 
avoided. Depending on program work loads, the 
secondary programs may contribute toward the 
cost of animal maintenance. Fees for services 
rendered to user investigators (research re- 
source in Figure 3) provide one third of LEM- 
SIP's operating income.
