الوصف: Bulk and grain density, porosity, and magnetic susceptibility of 67 individuals of Ko\v{s}ice H chondrite fall were measured. The mean bulk and grain densities were determined to be 3.43 g/cm$^\text{3}$ with standard deviation (s.d.) of 0.11 g/cm$^\text{3}$ and 3.79 g/cm$^\text{3}$ with s.d. 0.07 g/cm$^\text{3}$, respectively. Porosity is in the range from 4.2 to 16.1%. The logarithm of the apparent magnetic susceptibility (in 10$^\text{-9}$ m$^\text{3}$/kg) shows narrow distribution from 5.17 to 5.49 with mean value at 5.35 with s.d. 0.08. These results indicate that all studied Ko\v{s}ice meteorites are of the same composition down to ~g scale without presence of foreign (non-H) clasts and are similar to other H chondrites. Ko\v{s}ice is thus a homogeneous meteorite fall derived from a homogeneous meteoroid.
