EDITORIAL In March 1962, Professor C. J. Dreyer succeeded Professor Hurst as Chairman of the Executive Committee. We welcome him most cordially and assure him of our co- operation at all times. This issue of the Journal of the South African Logopedic Society consists of articles by overseas contributors. Ruth Clark worked in South Africa some years ago and we are privileged to publish her review of recent research on the parietal lobes, proprioceptive Sensibilities and tactilc and kinesthetic abilities in speech production — avenues of investigation which offer exciting possibilities for future work. Felix Trojan and Herta Weihs have provided us with some idea of the Conti- nental approach to speech and voice therapy. Their discussion of factors relevent to a correct diagnosis of a speech or voice disorder covers a wide field and is most interesting. 1 JOURNAL OF THE SOUTH AFRICAN LOGOPEDIC SOCIETY R ep ro du ce d by S ab in et G at ew ay u nd er li ce nc e gr an te d by th e P ub lis he r (d at ed 2 01 2)
