| Abstract Note | The idea of the organization of a Symposium on Spiral Structure came at a special meeting of Commission 33 on Spiral Structure during the 12th General Assembly of the IAU in Prague, 1967. So much interest was shown during this meeting that one of us proposed a special Symposium on the 'Spiral Structure of Our Galaxy' for 1969. The response was immediate and it was finally agreed upon holding the Symposium in Basel, a center of galactic research in the center of Europe. During the next months a special 'List of Problems', related to this Symposium, was sent to many prospective participants by the president of Commission 33. This stimulated an increase of interest in problems of galactic spiral structure and a con?? centrated effort on some problems. The organizing Committee of the Symposium was composed of Drs. L. Woltjer (president), W. Becker, A. Blaauw, B. J. Bok, G. Contopoulos, F. J. Kerr, C. C. Lin, S. W. McCuskey and S. B. Pikel'ner. Most of the work for the organization of the Symposium was carried by Dr. L. W oltjer. The Local Committee, composed of Drs. W. Becker, U. W. Steinlin, R. P. Fenkart, and G. A. Tammann, made every effort to secure the success of the Symposium. Most of the credit goes to Dr. Steinlin. The Symposium was supported financially by the IAU and by the Swiss National Science Foundation. The meetings took place at the University of Basel, which provided also secretarial help and many other facilities |

| Title | Tables of Ordinary and Extraordinary Refractive Indices, Group Refractive Indices and h???o,x(f)-Curves for Standard Ionospheric Layer Models |

| Abstract Note | The N(h)-Working Party, a Group in Commission III of URS! (URS! Information Bulletin No. 112, p. 12) suggested these calculations of ordinary and extraordinary refractive indices n , vertical group refractive indices c/U , and virtual o,x o,x 1 heights h (f), for an Epstein, cosine and parabolic layer model. c ist the free 0 X 1 space velocity of light . U and U denote vertical ordinary and extraordinary 0 X group velocities. The data are intended to facilitate real height (h) computations from 1 1 observed, h (f)-traces. Especially the h (f)-data are intended also to allow o,x o,x for tests of existing reduction methods. For ionization minimum investigations an additional set of tables is presented. These tables represent the virtual paths 1 6 h (f) of sounding pulses which penetrate an ionospheric layer of parabolic o,x 1 shape; they can be used together with the abovementioned standard h (f)-curves o,x 1 to give ordinary and extraordinary h (f)-traces for any combination of a lower O, X parabolic layer and an upper Epstein, cosine or parabolic electron density distribution. Ordinary group refractive index tables have already been published by D. H. SHINN [ 1] 1 and by Vv. BECKER [ 2] ??? Their value s of cp , the angle of inclination of the earth s magnetic field, are slightly different from those used here. These tables may be used 1 as additional sets for interpolation purposes. D.
