Ce gation: The biological test program is planned to be a cooperative aativity involving ronvresentatives of the Atomic nergy Commiasion amd the National Hilitary Isteblichment. The individual studies will be performed under contract with the ASG. It is contemplated that all the biolo-ical research groupd will obtain their animals from the animal colony, and will share the facilities of the biological lsborntory. Asa corollary, they should also share in tha cost af the biologie al teat vrogrem.
