The basic paper has no* been finalised but publication will not take place until later in the year when all the references have been added and when the paper has been accepted by a reputable eedlcal journal. The paper Is not incompatible with that produced by Or.Allardice a couple of years ago and indeed he contributed in the early stages towards the forwlatlon of this paper. When published the AIA paper will be a very Important reference document for the asbestos Industry and, indeed, for regulatory authorities in many countries. I am therefore sending you a copy of the final draft which can be used for internal purposes a* required. However, as publication has not yet taken place I shall be grateful if you do not use it for external purposes or give any publicity to it. ' T ! f . *, H.O.S.
