DUTRA--EXPERIMENTAL BERYLLIUM GRANULOMAS 89 Relative to the physical properties of the two samples of beryllium oxide, the reaction to sample A was considerably severer and more sustained than that to sample B; studies of solubility and electron microscopy have revealed that the rate at which beryllium oxide goes into solution is greater with samples that have been calcined at relatively low temperatures than with samples calcined at higher temperatures8; furthermore, the former seem to have a much greater surface: weight ratio than the latter.8 h ' SUMMARY Beryllium granulomas have occurred in the skin and subcutaneous tissues of pigs after implantation of phosphor powders which contain beryllium oxide. > Nonspecific granulomas of foreign body type occurred in the tissues into which metallic beryllium or beryllium oxide alone had been implanted.
