Laboratory. RE CASTROL OIL SUPPLIED BY MESSRS. INSTONES. RECEIVED The small sample of oil in the bottle No.1941 was found to be similar to Wakefield's ordinary Castrol as judged by the Castor oil present, the acidity, specific gravity and opem flash point. A complete viscosity test could not be done accurately owing to the small quantity of oil available. Hl. HE | ||
