Complete surface photometry has been obtained for 36 E-S0 galaxies, 33 being members of the Virgo E cluster, on the basis of plates mostly taken with the 1.20 m, f/6, telescope of the Observatoire de Haute-Provence. The data are compared with the results of previous surveys. The results are given as tabulations of the parameters describing ellipses fitted to the isophotes. The axis ratio c/a and major axis position angle P, are tabulated down to a level of B brightness μ0 = 25 to 26. The "radius" of isophotes r = (ac)1/2 is given down to μ0 = 27 to 28. A preliminary discussion of the data is presented. The μ0(r) relations for E galaxies are compared to the r1/4 interpolation formula, and it is shown that systematic deviations are observed and are similar for galaxies of similar luminosities.
