Abstract
Heavy-metal salts, mostly in 0.5 [image] concentrations, were used for tissue fixation and for albumin and gelatin precipitation. Tissues from dog, cat, and rabbit were stained in acid and basic stains. The atomic weight of the cation of the salt influenced its precipitating power. Tissue-hardening or high precipitating efficacy of a given salt did not always give good tissue preservation.
