    Foreword THE techniques included in this Bulletin were compiled during the past six years by the Publications Committee* of the Conference of Bacteriologists of the National Agricultural Advisory Service in England and Wales. Bacteri- ologists from the National Institute for Research in Dairying, Shinfield, Reading gave valuable assistance. Some of the basic bacteriological techniques are modifications of those originally used during the Clean Milk Competitions of 1924—35, others are based on new methods introduced during 1942—46 in connection with the National Milk Testing and Advisory Scheme, while some are advisory or statutory tests developed by advisory bacteriologists during the past 20 years. They were originally issued as provisional techniques and after continuous use in National Agricultural Advisory Service and Milk Service laboratories for several years were eventually approved by the Publications Committee as standard methods. The various sections give the technical details necessary for carrying out a process by a standard method so as to enable consistent results to be obtained at different laboratories. It has not been considered possible, within the scope of this Bulletin, to enter into any discussion of the principles on which the techniques are based, or to make recommedations regarding the interpretation of results. Nevertheless, subjective notes on the advisory approach, as well as on sampling and investigational procedures, have been included. N. H.
