The surface brightness distribution of hot intracluster gas in the 2A 0335+096 cluster of galaxies is presented. The intracluster gas is found to be nonisothermal. The surface brightness is deprojected to obtain density and temperature profiles of the intracluster gas. It is derived a central density of 0.023/cu cm and a central temperature of 1.8 x 10 to the 7th K. It is found that the hot gas is cooling and accreting onto the central dominant galaxy. Mass inflow rate between 14 and 200 solar masses/yr is derived for the gas inside a radius of 150 kpc from the center. Including the effects of heat conduction on the flow reduces the mass flow rate only beyond 25 kpc from the center. Assuming hydrostatic equilibrium, a total binding mass of 7.6 x 10 to the 13th solar masses is found within the maximum extent (720 kpc) of the source observed. The total X-ray gas observed has 38 percent of this mass.
