dc.description.abstract	The authors present here new results on the periodic modulations in the optical light curves of EX Hydrae observed during 1982 - 84. The period analysis has been done using synchronous summation and discrete Fourier transform methods. The authors report new periodicities at 34.7 min and 26.7 min apart from confirming the detection of 46.3 min modulation recently reported. They also include their data to derive the rate of decrease of the 67 min period.	en
