In centrifuged eggs, the injection is made where the natural oil droplets arc no longer found, although protoplasm and cortical alveoli are still promt in the egg cortex. In spite of the absence of the natural oil droplets around the injected oil, it can migrate toward the vegetal pole all by itself. ' >n the other hand, by strong centrifugation, the protoplasm of the unfertili/ed egg can be shifted in the animal region and the oil is massed at the vegetal pole bv .orienting the egg by a capillary tube-. As the result, a blastodisc is formed at the.
