Abstract
Digital data of polarization vs. field on triglycine selenate at close ly spaced temperature intervals (DELTAT almost-equal-to 0.015) in the vicinity of the quasi-tricritical point of triglycine selenate have be en collected. These data fulfill very well the scaling equation of sta te e -/+ = -/+ p + + (1/5)p5 (where e- and e+ correspond to T < T(c) a nd T > T(c), respectively) where p = = (P(s)/P(so))/{1 - T/T(c)}1/4 an d e = (E/E(so))/{1 - T/T(c)}5/4 are the scaling variables, with tricri tical exponents beta = 1/4, delta = 5.
