| Abstract: | The merits and demerits of Elias' method were analysed. The method was modified by measuring directly projection length of the capillary, and calculating inclination length with Pythageras' law and estimating the density of the capillary by the total length of the capillaries. The specimen of the brain and midbrain of rats and the spinal cords of babies and children and pigs were measured by the modified method and compared with those measured by Elias' method. The results showed that the modified method was more practical and reliable than Elias' method. |
