It was agroed that an outline for the oonduot of future spinning teats and for a sorlos of testa on the laboratory carding meohlne should be drawn up and circulated for orltlolam. An effort will be Bade to eooure Information fros Ingland re tarding manufacturing preotioes in that oountry The national Rosearoh Counoll staff reported the results of prollalnary spinning teats on washed asbestos fibre* Washing reaoTod a large amount of duat and produoed a fibre which could be spun without henry losses, tho not result being similar to that with unwaahod fibre* Zt was considered worth while to oarry out preliminary tosts on the Impregnation of washed and unwasnod.fibro*, me ooamlttoe discussed the quostion of magnotlo iron in aebeatoe, one of oonsldorablo importance when aibostos la to bo used for olootrioal insulating purpot es. In studying this quostion tho national Bosoaroh Counoll Is oooporatlng with the Aaerloan Sooiety for Testing Materials. V m* sffeot of various milling aachinos on fibre rat reported by the laboratory staff, which has been studying this question by mlorotoopie methods* Various changes In oooBerolal praotloe were suggestod.
