We report new evidence obtained between 500 {mu}K and 150 mK for the importance of interactions between tunneling two level systems in structural glasses. After the application of a large dc electric field we observed logarithmic relaxations in {epsilon}{prime}({omega}) and {epsilon}{double_prime}({omega}) for up to 10{sup 4}s. The frequency dependence of the relaxation in {epsilon}{prime}({omega}) observed at higher temperatures vanishes for temperatures well below the minimum of {epsilon}{prime}({omega},{ital T}) and we find {epsilon}{double_prime}({omega}){proportional_to}{ital T} below the high temperature plateau, both qualitatively in agreement with models involving interactions. {copyright} {ital 1996 The American Physical Society.}
