Design and Accuracy .—The accuracy limitations of the general laboratory research type of porosimeter are discussed and the principles of design indicated. McLeod‐Gauge Type of Porosimeter .—A new type of porosimeter is described with which the pore volume of any test piece may be directly determined within 0.01–0.02 cc. Results with Electrical Porcelain .—Tests of eight pieces of electrical porcelain indicated a porosity of 0±0.01 per cent. This result was confirmed by dye penetration tests. An Apparatus for Measuring the Porosity of Full Size Brick .—A simple and rapid apparatus for measuring the porosity of full size brick by the “General Method” (Jour. Amer. Ceram. Soc. , 5, 113–16 (1922)) is figured and described.
