Quantitative estimation of RNA and nitrogen for fore-, mid-, hind-brain and spinal cord of the differentiating central nervous system of chick has been made. It is found that the amount of RNA and that of nitrogen do not remain constant in the various phases of ontogeny. 2. Quantity of RNA and of nitrogen are high in most of the tissues upto 12 days of incubation. 3. Increase in the concentration of RNA usually proceeds that of nitrogen. 4. The observations heve been discussed with respect to differentiation of the central nervous system.

已对鸡中枢神经系统分化过程中的前脑、中脑、后脑和脊髓的RNA和氮进行了定量估算。结果发现，在个体发育的各个阶段，RNA和氮的含量并非保持恒定。2. 在孵化至12天的大多数组织中，RNA和氮的含量都很高。3. RNA浓度的增加通常先于氮浓度的增加。4. 已就这些观察结果对中枢神经系统分化的意义进行了讨论。
