STUDIES ON THE FORMATION OF PEARLS. I. -ON THE RELATIONSHIPS OF PROTEINS AND CaCO3 CRYSTALS IN THE LAYER OF BAROQUE PEARLS-

“…Protein content in volume was calculated from specific gravities (7). The results obtained are shown in Table 1.…”

“…Moreover the latter was divided into the large· crystal layers (2-5) and no crystal layers (8)(9). (2)(3)(4) are the thick crystal layers which contain a radial protein structure, (5) is a random crystal layer, and (6)(7) are independent giant crystals.…”
