The present work gives full details of the permeability and the surface area in refractory bricks among a series of studies necessary for the quantitative interpretation on metallurgical phenomena concerned with the pores. The former was investigated by the widely controlled pressure of various fluids and the latter by the Kr adsorption for the same brick specimens as used previously. The discussion has been ranged to the differences and the relations among the results previously obtained in the separate measurements. The main results are;<BR>(1) The pressure method results in the consistent permeability regardless of the kinds of the fluids.<BR>(2) Diffusion contributes to the gas flow through bricks due to the pores with the sizes less than 10 times the mean free path.<BR>(3) The porosimetry results in the surface area which is one and a half time as large as the Kr adsorption method in case of the bricks.
