We observed that the hapatic liquid crystal lipoid droplets (LCLD) of newborn ducks and newborn pigeons existed mainly in hepatic cells of hepatic cord and less in blood sinus, respectively with Braggdvalues of 36. 8 Å and 38. 4 Å obtained by small-angle X-ray scattering (SAXS). X-ray difraction (XRD) patterns made known that the fresh livers of newborn ducks and pigeons, dealt with freezing and thawing at room terperature, corresponded respectively to their own LCLD lipid crystals. The XRD data comparison indicated that the hepatic LCLD crystal of newborn pigeons was distinctively different from the hepatic LCLD crystal of newborn ducks and chickembroyos. They belonged in two different kinds of crystal phases. But any one of them was phase-mixture and contained a little of the other, each other.
