keep labor costs down and to attract supe- 
rior research-oriented personnel. 
8. Overall economy in housing, equipment, 
and operation, by careful analysis of all 
costs. Emphasis has been placed on achiev- 
ing maximum research results per dollar 
of expenditures. 
The cage design for all animals, including the 
5' X 5' X QVi' chimpanzee cages, is derived 
from the labor saving cage systems of the poul- 
try industry. All cages are suspended on walls 
of the animal room; a 150 lb. baboon cage can 
be easily removed by one technician using 
LEMSIP's cage lifter; the heavy large chim- 
panzee cages are easily moved on either over- 
head trolley tracks or by fork lift cage lifters. 
LEMSIP's dry system of waste collection con- 
sists of plastic sheeting placed under the cages 
and collected every 24 hours for smokeless in- 
cineration. 
All animal housing and laboratories consist 
of modular transportable units designed by the 
LEMSIP staff ; the units are far less expensive 
then conventional buildings and allow flexibility 
of housing design. 
The modular housing units as well as the cag- 
ing and other equipment have been purchased 
for LEMSIP by participating institutions (Fig- 
ure 2). Several of them have adopted LEMSIP 
caging for their own intramural animal hous- 
ing, so that the animals can be easily housed

when brought from LEMSIP to the investiga- 
tor's institutions when required by research 
protocols. LEMSIP activities are supervised by 
the Utilization Committee consisting of repre- 
sentatives of users of the Laboratory. 
A basic objective of our Laboratory consists 
of helping investigators establish their own re- 
search programs at LEMSIP or in their own in- 
stitutions, or in both. In such a way, the profes- 
sional know-how of our staff, the animals, and 
the available facilities are used to support the 
research of many workers, who in turn provide 
their own professional abilities to solve the 
problems of research and animal care that are 
outside of our own area of competence. The col- 
laboration is not limited to the help of scientists 
from various institutions in problems arising in 
our own laboratory ; we are also able to arrange 
exchange of information on capabilities and 
needs, as well as collaboration between workers 
from different institutions whose specialties 
complement one another's areas of research. 
For instance, help of an obstetrical team from 
New York has made possible investigation of 
viral transfer from mother to fetus carried out 
by a New England team in our laboratory. 
Each of the consultants is motivated by his 
interest in the primate laboratory that supports 
his own research programs, and by the benefits 
which he, in turn, derived from the consulta- 
tions provided by others. Thus, the primate lab- 
oratory gains the time, effort, and talents of 
people who might otherwise not be available for 
consultations were it not for their scientific mo- 
tivation. 
Many research projects require only periodic 
supply of a large number of fresh normal sam- 
ples, as, for example, studies of blood groups, 
serum specificities, biochemistry of hemoglobins 
and viral flora. In order to justify better the 
maintenance of relatively large numbers of ani- 
mals for any one of such purposes, additional 
investigations are carried out on the same ani- 
mals, according to research plans which do not 
interfere with the normal condition of the si- 
multaneously investigated parameters. More- 
over, a large number of animals can accommo- 
date more research projects per animal by al- 
lowing for rest or incubation period on one kind 
of experiment while using the same animals in
