The introduction of isospin by H]~IS~N~nG (1) to characterize the symmetry of the neutron and proton aIld the subsequent developments (2-8) associated with SU2, SUn, U3, SU3 and the quark models, have left the theory of elementary particles with the still-unsolved problem as to the origin of these internal symmetries as well as their broken character. Unlike the case with ordinary spin, isospin and its associated (( strong )) charges have not as yet emerged in any generally-accepted way as a consequence of a deeper analysis of the symmetry properties of space and space-time as described by the rotation group and the Lorentz-Poincard group (7). While it is certainly consistent with what is known to take the view that the space-time symmetries and the hadronie internal symmetries co-exist but are quite independent, it is also possible to take the opposite view and to see where it leads. This latter approach is followed here. ~Wnat I shall do is to give an empirical equation relating the spin of the hadrons to their isospin, strangeness and charm. I shall then present tables of the hadrons to show that the equation applies to all the observed hadrons for which the quantum numbers are known (s). For greater completeness, the F-mesons and the T(9440) have also been included in the tabulations although the quantum numbers are apparently still not completely settled (s). Also, although the intent ion of the analysis was to work with the observed hadrons, it turns out that the equation also applies to the quarks, and they are included in the tables. Since the photon formally fits in the same table with massive vector mesons it too has been included for suggestiveness. The approach to obtaining the spin equations below is quite heuristic. I t is the hope that a more theoretical basis will be found, perhaps in some nonclassical departures
