Travel will be with TWAfrom London Heathrow to Kennedy, New York,and will include coach transfer to Atlantic Cityand accommodation on a room-only basis inselected hotels close to the Convention Centre.Additional requirements such as transfer toHeathrow and personal onward itineraries afterthe meeting can be catered for, as well as carhire, assistance with visa3 etc.The pressure on hotel space in Atlantic City isenormous, as any visitor to previous PittsburghConferences will testify. Our rooms are alreadyreserved, so booking with the RSC Group isyour guarantee of good accommodation and atrou ble-free meeting.For further details, please quote ReaderService Number 001 or telephone KarenMizel on 01-437 8656 extension 250.BUREAU OF ANALYSED SAMPLES LTD.announce the availability of two newEURONORM CERTIFIEDREFERENCE MATERIALSECRM 287-1 High Boron Stainless Steel(chip or disc material)ECRM 587-1 18.7% B Ferro-Boron(finely divided material)for further details and/or a copy of thelatest BAS Catalogue or OverseasReference Materials List, write, telex ortelephone to:BAS Ltd., Newham Hall, Newby,Middlesbrough, Cleveland, TS8 9EATelex: 587765 BASRIDTelephone: (0642) 317216001 for further information.
