A Mattermotive Law of Induction and an associated Mattermotive Law of Induction pertinent to Pair Production are proposed and discussed. It is shown that the proposed induction process, which occurs in Triplet Production, also occurs in the Pair Production process. The possibility of Multiplet Production by induction is also discussed. The possibility that these Laws of Induction may be universal much like Newton's Law of Gravitation is proposed. 5787 pairs, 1935 triplets, 106 quartets, 10 quintets, and one sextet have been observed and studied. The frequencies of occurrence of multiplets together with energy distribution of the low energy partners are presented. In addition, the ration of pairs to triplets in the 2 to 90 Mev photon energy range is presented.
