The subject of this discussion is not one which readily lends itself to division into separate compartments but, for the purpose of presenting our respective papers, Mr. White and I have agreed to divide the subject between us on the basis that he will deal with the legal aspects of international co-operation as between the participants in the project and third parties, while I propose to discuss some of the legal aspects arising out of the relationship between the companies engaged in such projects. As I have implied, such a division of the subject must of necessity be an arbitrary one, and it is evident that there will be many areas where the two sides overlap, so that they cannot in practice be treated in isolation, and Mr. White and I have felt free to include in our respective papers, matters arising from our own experiences which in some cases may be more appropriate to the other's half of the programme.
