We have used the archive of data collected from Cygnus X-3 with the Rossi X-ray Timing Explorer (RXTE) to search for periodic or quasi-periodic oscillations and to look at the spectrum of the timing noise in these data. The presence of high frequency timing noise would put a strong constraint on the size of the region in which the X-ray emission is produced and imply a limit on the scattering depth of the atmosphere of the companion star. The presence of a periodic signal would be definitive proof that the compact object is a neutron star. The absence of a periodic signal will have to be interpreted in terms of the inferred scattering depth of the companion's atmosphere. Discovery of quasi-periodic oscillations will help us understand the Cygnus X-3 system by analogy with other high energy astrophysical systems that produce quasi-periodic oscillation of various sorts through various mechanisms.
