| S/W (L) copy to Dr. HS{Lord Ernest Hives - Chair} X4117 L/D (517) See me H6/H19.11.31. HS{Lord Ernest Hives - Chair} GAJ-57. - Miss Latilla. Will you kindly refer to Memorandum No. 1830 and to the allegation that BP.Plus spirit forms a blackish deposit liable to cause the air valve to stick. We should be glad to know whether you have found any cases of this or whether you have experienced anything of the kind on any occasion when you have tested or used BP.Plus. As you know, we occasionally get requests about the use of this spirit and we have been under the impression that there was nothing against it except perhaps it poisonous nature. H.{Arthur M.
